The site chat plays a whole flow

Open the chat on any page and say show me a flow. Yui plays the first run of the app on the stage, one screen at a time with a branch on your answers, then one Send, and answers what you told it. This is the flow it runs.

Hi, I'm Yui

Three quick questions, then I suggest your first agents. You can change any answer before you send.

How much do you know about AI?

An agent, in one line

An AI helper with one job, like a trainer or a planner. It remembers you, and in Yui it answers with screens, not walls of text.

You talk or tap
It answers with a screen
You stay in charge

Do you run an agent already?

Which ones do you want?

Plug in the agent you run

Install the Yui plugin and pair with a code. Each agent you picked becomes a profile on it, with its own look. The steps are at yuigui.com/start.

Yui brings the screens, you bring the agent

Yui has no built-in agent yet. Set up Hermes once, free, on your own computer, and each agent you picked becomes a profile on it. The steps are at yuigui.com/start.
