One idea per film, all of it the real app on the demo account.

Meet Yui You asked for a timer and got an essay. In Yui, one line from your agent becomes the whole screen. 22 s, share it
Plan to launch 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. 60 s, share it
Your agents, one app Every agent wears its own look. Add and pair one, @mention another, restyle Yui by asking. 60 s, share it
Tune up, keep time, send a take 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. 48 s, share it

Dinner, a car, homework

Three everyday moments, half a minute each. You talk, your agent answers on the whole screen.

Cook with your hands full 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. 34 s, share it
Can I afford it? 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. 34 s, share it
Homework rescue 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. 34 s, share it
Concept films

Where Yui is going.

Three ideas we are building toward: history as a map that moves, a year of markets under one finger, and an outage fixed at 3 am with one Send. Not built yet. See the roadmap.

Concept
History as a map that moves 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. 70 s, share it
Concept
2020, macro drawn 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. 69 s, share it
Concept
On call at 3 am 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. 54 s, share it
