How it works

Post it. Swipe. Talk.

No followers to collect and no profile page to polish. You post something and find out who wants to answer.

  1. Post something

    A thought, a question, a "good morning", or up to three photos. It goes into the public feed.

  2. Swipe the feed

    Flip through what other people posted. Like it, react with a face, or tap Reply.

  3. Chat in private

    Replies open a private chat between the two of you. Your chats list shows who wrote and when.

Inside the app

Two tabs. That's the whole app.

Public is the feed. Private is your chats. Switch with the toggle at the top.

Every line of code: 100% written by AI

All of the code behind Hi Chat, in the app, on the server and on this website, was written by AI agents with Claude. The agents also simulate, test and analyze that code before anything goes live.

What this means for you

The code in Hi Chat is written 100% by AI. Not just parts of it: every screen in the app, everything on the server and all of this website. AI agents write the code, simulate how people will use it, test it and analyze it for bugs, speed and security.

And because AI keeps getting better, Hi Chat keeps getting better too. Every new generation of AI means cleaner code, faster fixes and new features sooner. Hi Chat grows with it.
