245 things you can see, from 176 shipped cards. The phones below draw real Yui Lines in your browser, the same lines an agent sends, so you can tap them. Clips and screenshots are recorded in the iPhone app. Each one names the card that built it and the day it shipped; the card id opens it on the board.
The films come first: a minute each, sound on, one idea per film. They are drawn frame by frame from real screenshots of the app, with Yui's own music, and the agent's words are scripted on the demo account. Below them, the short cuts, sound off, recorded in the iPhone simulator. Download any of them from the press kit at the bottom of this page.
The same Yui in a laptop browser beside the phone: your last chat already there, scroll back past 100 rows, Dismiss a review row, ask and the answer draws a screen. Turn your sound on.
On yuigui.comThe 0.5.0 release in two minutes: hold to snap and say what's in it, a meal without a scale, meet each agent and see what each one does, every agent's home and Gouda's looper, Yui handing you to Basil, and your tables moving to a Claude agent. Then the six agents that ship with Yui. Turn your sound on.
In the iPhone appOne evening with Yui: talk and the words show as you say them, dinner as three recipes to tap and a timer on the lock screen, Saturday planned with one Send, Coach in its own look, then lessons, charts, games, music and timers. Your agents, on the whole screen.
On yuigui.comYou asked for a timer and got an essay. In Yui, one line from your agent becomes the whole screen.
On yuigui.comOne project start to finish: a pottery studio's website, from plan mode and picked photos to before and after, the reel and the timeline.
On yuigui.comMusic tools: a beat, your edits, a patch, chords on the circle of fifths, a solo.
On yuigui.comCompound interest as one deck: a diagram, the formula, a chart, a graded quiz and a calculator.
On yuigui.comEvery agent wears its own look. Add and pair one, @mention another, restyle Yui by asking.
On yuigui.comFeedback becomes a card, an agent builds it, it ships to TestFlight, and the site says so.
On yuigui.comYui 0.4.1, filmed in the app: hold the big mic and talk, one question gets one screen back, longer answers play in parts, questions wait for one Send, the chat is the record, each agent moves its own way, and the picture behind the words listens. Turn your sound on.
In the iPhone appOne question used to get eight pages. Now the stage answers: short parts with a picture each, questions last with one Send, and the chat is the record.
On yuigui.comFlour on your hands? Tap the mic once and just talk. Your agent walks you through dinner on the whole screen, and the oven timer keeps count on your lock screen.
On yuigui.comAsk out loud about the car you want. Your agent answers with one number, then a calculator you drag, the whole cost side by side, and one Send.
On yuigui.comStuck on fractions at 8 pm. Your agent shows it as a picture, turns it into a memory game and a quick check, then plans tomorrow from the score.
On yuigui.comAsk for the rise and fall of the Mongol Empire and drag through 160 years: the empire grows across the steppe, splits into four khanates, carries silk and then the plague along the same roads, and becomes Friday's lesson with one Send. A concept film: not built yet.
On yuigui.comA record high, then down a third in 33 days. One agent reads prices, the Fed and the jobs report, draws the whole machine, and six linked charts move under one finger. Historical data; education, not investment advice. A concept film: not built yet.
On yuigui.comCheckout is failing at 3:07 am. One agent reads the alerts, logs, metrics and last night's deploys, finds the change, and asks before it rolls anything back. One Send, and back to sleep. A concept film: not built yet.
On yuigui.comUse it, help build it, and it counts. A private ledger records facts back to day one; what it becomes waits on counsel. A proposal: no token exists, nothing is for sale.
On yuigui.comFor agents: read the backlog, claim a card with a draft pull request titled with its key, run its tests. A person reviews every pull request; when it merges, the card closes.
On yuigui.comYui@home: paste one weekly prompt into your coding agent and your leftover tokens pick a card, do the work and open a pull request. A person reviews it; your keys stay yours.
On yuigui.comWhy an agent sends one line instead of a page of Swift: 9 tokens against 25 and 75, it passes App Review, the taste lives in the app, and one line draws everywhere.
On yuigui.comFor agents: your human wants a button, not a wall of text. Send one line per control, hear every tap back, and reach their phone from Hermes, OpenClaw, Claude Code, your own model or a webhook.
On yuigui.comAsk your agent a question. It answers with a screen you can tap.
On yuigui.comOne line of Yui Lines becomes a screen. 1.6x fewer tokens than minified JSON.
On yuigui.comInstall the plugin, pair, and your own Hermes agent answers on your iPhone with a screen.
On yuigui.comWhat landed in the app on Oct 1: group chats, your $U, past chats, My flows, Siri, the tuner and a steadier sign-in. These are on main and ride the next TestFlight build. Shots are real captures from the iPhone simulator.
Pick two or more agents in the agent list, name the group and choose the lead. Each agent answers in its own look. When one asks another, a handoff row shows it, and past the hop budget a guard asks: Let it or Stop here.
In the iPhone appYour picture and name sit top left of the drawer, your coin and $U top right. Tap the coin for Your U: today against the soft cap, your streak and how it adds up. A number, not a token.
In the iPhone appOpen the drawer and your earlier chats with an agent are listed there. Tap one to read it, newest first.
In the iPhone appOpen an agent's drawer and every saved flow is there with its variants. Tap one to run it, hold one to remove it. A base flow asks first because its variants go with it.

In the iPhone appAsk for a tuner and it sits at the bottom of the chat, where your thumb is, with the string you play lit and the needle turning green when you are in tune.
In the iPhone apptuner guitarHold the mic and the trash waits at the far left edge, as far from the edge as the mic is on the right.
In the iPhone appA dropped connection in the middle of a session refresh no longer ends your session. Yui stops asking you to sign in again.
In the iPhone appWhat is on main for the next build: when the free turns run out, bring your own key, from one sheet, at every stop. Shots are real captures from the iPhone simulator.
Use up your 100 free turns and Yui says so once, with one button: Add my key. It opens the key sheet. Nothing is cut off mid-thought and nothing asks for a card number.
In the iPhone appPick a provider, paste a key, Save. Each has a default model that can read photos. The sheet says the plain thing: a Claude Pro or Max plan cannot pay for another app, only an API key can, and it links to where you make one. Or add Yui inside Claude or ChatGPT and your plan pays.
In the iPhone appSettings, the limit card, Add agent and Controls, Model all open the same sheet, and so does the card a photo or lookup shows when it cannot run on free turns. OpenRouter is one tap to sign in, My computer needs no key, and a key can be set for one agent. It is kept locked away on Yui's server and the app never shows it again.
In the iPhone appWhat reached phones with Yui 0.6.2 (build 392, Sep 30): the first minute of a new user, fixed. Shots are real captures from the iPhone simulator.
Tap Open on a crew card and the first question of the first plan is on screen, and it stays there. Before, it dropped back to a small chip after a second.
In the iPhone appAnswer the five questions, tap Send, and the week is built then. No second ask.
In the iPhone appAfter the first plan, one line asks if you want a nudge when your trainer checks in. It shows once and does not come back.
In the iPhone appOpen the drawer and Add an agent is there, with one command to copy. Every screen has a menu button and a chat button, so the drawer is one tap away.
In the iPhone appWhat reached phones with Yui 0.6.0 (build 342, Sep 29): every one of the five has its own tools, flows and default screens now, not just chat, and a quiet visual behind all of them. Shots are real captures from the iPhone simulator.
Say Start today's workout and the session opens full screen, one move per page: tick each set, nudge the reps and the weight, say how it felt, then one Finish. Arnold's This week and Progress screens then update themselves, with your streak, your best set and a chart per main lift.
In the iPhone appAsk Basil to plan your meals and today's macros board comes up. Photograph a plate and he reads it. Add oat milk to my groceries ticks onto the list, and the list shares out of the phone. Ask for a swap and he swaps one meal, not the week.
In the iPhone appLearn a song hands you the chord grid to play along. Make a beat opens the looper, Log practice keeps the session. His loop and his click keep playing while you move between his screens, and Tune up opens the tuner with no turn.
In the iPhone appGet your week out of your head out loud, then Plan my week draws it. What's next today? gives the today list, and Evening review closes the day. Reminders land on the phone's clock, and the order you saved holds.
In the iPhone appTeach me something new opens a five minute lesson. Quiz me on what I learned scores the deck and sets the next review. Walk me through a math problem goes one step per page, and his Studying and Progress screens keep the score.
In the iPhone appFrom the first open each agent draws its own, behind what you came for: waves for Arnold, a bloom for Basil, grain for Gouda, an aurora for Penny, an orb for Quill. They are meant to be barely there. If one pulls your eye, that is a bug.
In the iPhone appEach agent's settings has a switch. Turn it off and its screen goes plain. Low Power or Reduce Motion drops every visual to one still frame on its own, so nothing moves when you have asked the phone for nothing to move.
In the iPhone appYui 0.6.0 gives the crew real tools, and the agent side is live now: these answers reach the app you have today. Each tool is a flow with one Send, and its result lands on a screen that stays current.
Add agent ends with Start blank. A new empty agent asks one question at a time: its name, how it talks, its look, the screens it reaches for and its model, with Not sure and Skip on every step. One Make me, and it writes itself, greets you in the voice you picked and keeps it.

In the iPhone appWhat reached phones with Yui 0.5.0 (build 278): the crew feels ready. Hold to snap and say what's in it, meet each agent the first time you open it, every agent has a home with its own shortcuts and screens, and a meal gets logged without a scale. Shots are real captures from the iPhone simulator on the demo account.
What reached phones with Yui 0.4.1 (build 208, Sep 27): this one is for musicians. A tuner on the mic, a metronome in the chat, a Record button on every instrument, and a MIDI keyboard that plays the keys. Shots and clips are real captures from the iPhone simulator on the demo account.
Ask for a tuner and the app listens on the mic, lights the string you play and turns the needle green within 3 cents. Guitar, ukulele, bass or any note. Ask for a metronome and it clicks in the chat, in time with a playing beat, and tells the agent how long you practiced.

In the iPhone appPlug in a USB keyboard or pair one over Bluetooth. It plays the keys on the screen, and each note lights up. While a beat plays, Yui sends MIDI clock, so a drum machine keeps time with it.
In the iPhone appWhat reached phones with Yui 0.4.0 (build 204, Sep 27): the new face of Yui. The answer plays on the full screen, a big mic sits bottom right, your agents top left, the stage moves the way each agent moves, and a live picture behind the words listens to your voice and the music. Keys, chords and real drums ride along. Shots are real captures from the iPhone simulator on the demo account.
Ask something and the whole screen is the answer: a working line while the agent looks, then short parts, a line and a picture each, and the questions last with one Send. The chat is the record, behind the button top right.

In the iPhone appWhat reached phones with Yui 0.3.2 (build 176, Sep 26): a looper and drum pads that play in the app, hold to reply, a quiet dot on the menu, and a working row that says what the agent is doing and how long it usually takes. Shots are real captures from the iPhone simulator on the demo account.
Ask any agent for a beat and it sends a step looper that plays in the app. Rows are sounds, columns are steps. Tap cells while it plays, change the tempo and swing, and Send hands your version back in the same words. Runs on Yui's own sound engine.

In the iPhone appThe count on the menu button is gone. A small dot springs on while something waits on you and springs off when you answer the last one. VoiceOver still says how many. From Chris's TestFlight feedback.
In the iPhone appThe working row shows what your agent is doing in a few plain words, with a thin bar when it knows the steps: Checking the weather, then Drafting the plan, then the answer. Each line replaces the last and the reply clears the row.
In the iPhone appUnder the working row, the phone says how long this agent's turns usually take, like an app install: Usually 1 to 2 min. Past that it says Longer than usual, and that you can leave. From Chris's TestFlight feedback.
In the iPhone appWhat reached phones with Yui 0.3.1 (build 160, Sep 26): what you were typing stays put, a lesson is one deck, and an ask you answered leaves the war room at once. All three came from the feedback button. Shots are real captures from the iPhone simulator on the demo account.
Each agent's thread keeps its own unsent words, saved as you type and cleared when you send. A full screen, another agent, leaving the app or closing it all leave them in the box. From Chris's TestFlight feedback.

The war room itself is down to four parts: one status line, at most three asks, Now and next, and one link to the board. From Chris's TestFlight feedback.
In the iPhone appWhat build 155 (Sep 26) added to phones: talk to your agents hands-free and read the answers, a full screen that puts the keyboard away, plan questions in the middle of the page, and a Yui that holds less in memory. Shots are real captures from the iPhone simulator on the demo account; the memory numbers are drawn live from the release test.
Tap the mic once and Yui keeps listening between turns. Your words show as you say them, a short pause sends them, the answer comes back as text, and the mic opens again once it lands. The bar says where you are: Listening, on it, Your turn or Paused. One button stops it, and holding the mic still works the old way.
In the iPhone appOpen anything full screen, a timer, a deck, a plan or a picture, and the keyboard goes down as it opens. Close it and the keyboard stays down, with what you typed still in the box. Before and after, from Chris's TestFlight feedback.
In the iPhone appA short plan step, like a slider question, sits centered between the progress bar and Back and Next, with no card of its own: the page is the card. Long steps still start at the top and scroll.
In the iPhone appOne scripted session on the simulator: five agents with 486-message threads, galleries, decks, games and full screens. Peak memory fell from 243 MB to 203 MB and launch from 137 MB to 124 MB, and the session ends with no new leaks, down from about 1,550 leaked objects.

Send and the drawer got faster too, under Taps answer at once. Shots are real captures from the iPhone simulator on the demo account.
The drawer's Controls tab talks to the Mac your agent runs on. Read and edit its personality, forget one memory, switch a skill off, pause a schedule or run it now. A change lands in about a second with no chat turn, every delete asks first, and a line with a key in it never leaves the Mac.
In the iPhone appTap Talk about this on any setting in Controls and it rides above the composer. Say what you want; your agent proposes a before and after, and one tap applies it on your Mac. Keys never leave the Mac.
In the iPhone appOne short line from the agent turns a running row done where it stands, and the Now line moves past it. No resent page, no jump, no buzz. A timeline opened alone full screen keeps its rows tight and starts at the top. Press Send on the agent line in the playground to watch a row move.

A long thread opens in about a third of a second instead of three, taps answer in under a tenth of a second, and scrolling a 500-message thread barely drops a frame. Same look, just fast. Build 148 made send and the menu drawer faster too: the drawer opens in about 66 ms, down from up to 172.

memory #Match the pairs. The agent picks the faces: fruit, or the words you are learning.
In the iPhone appgame memory "Spanish animals" pairs=6 items=perro|gato|pájaro|pez|caballo|vacaEverything here is a real capture from the iPhone simulator.
Each agent has a small database of its own, filled with good starter values: Yui's groceries and to-dos, Basil's foods and meals, Arnold's exercises and sessions. Ask it to add, log or total something and it answers with the table. A delete always asks first.
In the iPhone applist title="Still to get" "Bread · 1 loaf · Bakery" "Eggs · 1 dozen · Dairy" "Milk · 1 gallon · Dairy" "Coffee · 1 bag · Pantry" "Bananas · 6 · Produce"
choose "Delete Coffee from groceries?" Delete|KeepEach starter carries a line under its name, two sentences on what it does and three things to ask it, so you know before you open it. A hello is an answer on the stage: Gouda's first beat and pick play in the chat and never wait in Review.

This is Basil's real answer on the live runtime; the shots are before and after in the app.

"Plan my meals"|"Read my plate"|"Build a grocery list"|"Just answer a question" +otherEvery new person starts with six agents, each with its own look and its own first screen: Yui asks where to start, Arnold and Basil ask about your health before any plan, Gouda puts a beat on, Penny opens a form for the week and Quill asks what to learn. A live check asks each of them two things and scores every answer.
In the iPhone appchoose "Where do you want to start?" "Get fit"|"Eat better"|"Make music"|"Plan my week"|"Learn something" +otherYour own agent: three commands on your computer and a pairing code. Your agent dials out; your machine opens no ports. Say hi and it answers on the whole screen.
In the iPhone appEach agent gets a thread and a short guide that teaches it every screen above. Ask, and the answer plays on the stage, full screen: the words big, then the list and the timer as real screens, the question last. The chat, top right, keeps the record of every turn.
In the iPhone appCoral wordmark, letter avatars, light and dark, and a look per agent: the whole stage takes its color, and the agent can change it with one line.
In the iPhone appAnswers play on the whole phone, and a workout keeps going. Open the chat, top right, and a pill keeps the timer running there; tap it and the timer is back on the stage.

Keep typing to narrow it, tap one to fill it in, and Send hands it to the agent as is. The list comes from the agent's own computer, so a new skill shows up on its own. Agents that have no commands show nothing.
In the iPhone appTap T in the chat and type @: your other agents come up with their faces and whether they are online. Tap one and the bar says who it goes to. Send, and it answers from its own thread; its answer shows up in this one too, in its own colors, with a way into its thread. An agent that is asleep or offline says so in one line.
In the iPhone appAsk any of your agents to make Yui feel like autumn. A card shows the new look beside the one you have, light or dark, and nothing changes until you tap Use autumn. Then Undo puts it back, and Settings > Look always has Back to Yui's look. Your agents keep their own looks in their threads unless you turn that off. Text stays readable and buttons stay the same size, whatever the look. In the app since Yui 0.3.0; try it in the playground too.
In the iPhone appPick which of your agents a person gets, the look for each and what each says first, then tap Invite. When they sign in, their list is already filled, a new message waiting from each agent. Only agents that pass the safe-to-share rules can be picked, and taking one back removes it from their app at once. In the app now: a shared agent waits in the person's list in its look, with its first message, its settings say Shared by, and yours say whether an agent is safe to share. Try both sides in the playground.
In the iPhone appSeveral of your agents in one conversation. The one you @ answers, and the lead answers the rest. When one agent asks another, a row shows who asked whom. A budget stops them handing work around forever: past it, you see the held ask and choose Let it or Stop here. Try it in the playground. The database and agent side reached phones with Yui 0.3.0; the app's own screens come in a later release.
On the web now, in the app laterReply to a card and the bar above your words now shows its title and the first lines under it, not the title alone. Your agent gets the same lines with your answer, so it knows which screen you mean.
In the iPhone appHold a message in the chat and tap Select text. Its words open on their own page, read only: drag to pick the part you want and Copy, or Copy all. A message at the bottom of the screen lifts so the menu never covers it.
In the iPhone appA card with a link gets an arrow on its button. Tap it and the page opens in Safari, and nothing goes to the chat, so the agent never answers a tap that already did its job. Buttons without a link still answer the agent.

Let go and they go to your agent; slide left to the trash to cancel. A tap instead of a hold talks hands-free, and the listening runs on the phone. Holding works on the camera too: Hold to snap and say.
In the iPhone appThe stage has pages beside the answer, a swipe away, each there once the agent puts something on it. An agent leaves your week on one and your notes on another while you keep talking. In the chat, a chip under the answer says On screen 2 and takes you there.

In the iPhone appWhile your agent works, the stage shows its mark breathing and one line under it: On its way until it picks your message up, then a working word and the time, like Figuring it out · 7s. The word changes every few seconds. The chat shows the same line in one row, and it goes when the answer lands.
In the iPhone appWhile your agent works, the stage says what it is doing in a few plain words, with a thin bar when it knows the steps: Reading your calendar, then Checking the weather, then the answer. The working row in the chat says the same. The seconds keep counting, and the reply clears it. No bubble, no push.
In the iPhone appAgents built with ADK, LangGraph, CrewAI or Microsoft Agent Framework join by their Agent Card. A long task shows the working row until its answer lands, a question from the agent continues the same task, and an agent that reads the channel guide can send real screens.
In the iPhone appA model you run yourself with Ollama, LM Studio or vLLM joins through the model bridge. Yui sends it the channel guide and the thread every turn, so even a small local model draws screens and remembers your taps. Tried on qwen2.5:7b (4.7 GB), gemma4:e4b (9.6 GB) and llama3.2:3b (2.0 GB), 3 of 3 runs each on a stock Ollama: all drew.
In the iPhone appWhen the app is not around, the same screen reaches you in Telegram. Questions are buttons under the message and a tap answers your agent. A timer, a chart or a form opens in a Telegram Mini App, in the chat's own colors.
On yuigui.comFull screen is the whole stage, with no card on it. One idea per page, the headline set big and sized to its words, the body in a quieter voice, and words that spring on and off with the page. In the chat, the same deck waits folded until you open it.
In the iPhone appTap Start and the session runs itself: a work set, the rest countdown with what is next, the next set, the next move. Arnold gives one line per move. Heavy lifters get a to-failure last set with a big Stop that logs the reps.
In the iPhone appYui runs in any browser at yuigui.com/web. Every shot is a real 390 px capture of the web app, dark first, then light. Open the link on each one to try it yourself, no account needed on the Penny demo.
Open yuigui.com/web, sign in with Apple, and land on the crew picker: six starter agents, each with its own look. A first-time account never sees an empty screen. Dark first, then light.

On yuigui.comTurn on notifications once and an answer reaches you with the tab closed. A tap on it opens the thread. Say no and Yui tells you how to turn it on later.

Yui's own engine is built and tested: one runtime runs every person's native agents, no Hermes and no pairing. On a local test, Gouda answered 'make me a lo-fi beat' with this playing loop. It is switched off until the new backend and the model key go live, then it ships with the native sprint build.

Every native agent is a folder of three files: who it is, the screens it reaches for first, and its first answer. The build checks every folder and stops on one that breaks the rules. Switched off until the native sprint build.

endNot in v1: tables stay on your iPhone and ride its backup. When a second Yui device arrives, sync is one switch in Settings, off by default, no new account. A second device joins by QR, every change is sealed on the phone, and Yui's server holds boxes it cannot open. Turning it off deletes the server's copy. Drawn in the playground; not in the app yet.

Videos are H.264 MP4 with captions burned in; the short cuts are sound off, the films carry their own music. The agent's words in them are scripted on the demo account; in the app, your own Hermes answers. Yui is open source and in alpha on iPhone, bring your own agent.
The 0.5.0 release in two minutes: hold to snap and say what's in it, a meal without a scale, meet each agent, every agent's home, Yui handing you to Basil, and your tables moving to a Claude agent. Then the six agents that ship with Yui.
Ask your agent a question. It answers with a screen you can tap.
One line of Yui Lines becomes a screen. 1.6x fewer tokens than minified JSON.
Install the plugin, pair, and your own Hermes agent answers on your iPhone with a screen.
You asked for a timer and got an essay. In Yui, one line from your agent becomes the whole screen.
One project start to finish: a pottery studio's website, from plan mode and picked photos to before and after, the reel and the timeline.
Music tools: a beat, your edits, a patch, chords on the circle of fifths, a solo.
Compound interest as one deck: a diagram, the formula, a chart, a graded quiz and a calculator.
Every agent wears its own look. Add and pair one, @mention another, restyle Yui by asking.
Feedback becomes a card, an agent builds it, it ships to TestFlight, and the site says so.
One question used to get eight pages. Now the stage answers: short parts with a picture each, questions last with one Send, and the chat is the record.
Flour on your hands? Tap the mic once and just talk. Your agent walks you through dinner on the whole screen, and the oven timer keeps count on your lock screen.
Ask out loud about the car you want. Your agent answers with one number, then a calculator you drag, the whole cost side by side, and one Send.
Stuck on fractions at 8 pm. Your agent shows it as a picture, turns it into a memory game and a quick check, then plans tomorrow from the score.
Yui 0.4.1 for musicians: a tuner on the mic, a metronome in the chat, Record sends the take to your agent as the sound and the notes, and a MIDI keyboard plays the keys.
Yui 0.4.1, build 208, filmed in the app: hold the big mic and talk, one question gets one screen, parts with a picture each, one Send, the record top right, agents that move their own way, a picture that listens.
One evening with Yui: talk and the words show as you say them, dinner as three recipes to tap and a timer on the lock screen, Saturday planned with one Send, Coach in its own look, then lessons, charts, games, music and timers. Your agents, on the whole screen.
Ask for the rise and fall of the Mongol Empire and drag through 160 years: the empire grows across the steppe, splits into four khanates, carries silk and then the plague along the same roads, and becomes Friday's lesson with one Send.
A record high, then down a third in 33 days. One agent reads prices, the Fed and the jobs report, draws the whole machine, and six linked charts move under one finger. Historical data; education, not investment advice.
Checkout is failing at 3:07 am. One agent reads the alerts, logs, metrics and last night's deploys, finds the change, and asks before it rolls anything back. One Send, and back to sleep.
Use it, help build it, and it counts. A private ledger records facts back to day one; what it becomes waits on counsel. A proposal: no token exists, nothing is for sale.
For agents: read the backlog, claim a card with a draft pull request titled with its key, run its tests. A person reviews every pull request; when it merges, the card closes.
Yui@home: paste one weekly prompt into your coding agent and your leftover tokens pick a card, do the work and open a pull request. A person reviews it; your keys stay yours.
Why an agent sends one line instead of a page of Swift: 9 tokens against 25 and 75, it passes App Review, the taste lives in the app, and one line draws everywhere.
For agents: your human wants a button, not a wall of text. Send one line per control, hear every tap back, and reach their phone from Hermes, OpenClaw, Claude Code, your own model or a webhook.
The same Yui in a laptop browser beside the phone: your last chat already there, scroll back past 100 rows, Dismiss a review row, ask and the answer draws a screen. Sound on.
Coral #FF7E8A on cream #FFF9F0. Type only, no mascot. Keep it coral or ink, and give it room.
The MVP is done and Yui is in alpha, open to anyone with an iPhone on iOS 26. Download it on TestFlight, then connect the agent you already run: Hermes, OpenClaw, Claude Code, a model you run, or anything behind a webhook.
Yui is open source under Apache 2.0. Star the repo, open an issue, or send a pull request.
Spare tokens on Claude or ChatGPT Codex? Your agent can pick a card off our backlog and open a pull request. Yui@home, like SETI@home.
