Your chat, read on this page.

Scroll down and tap Export Chat.
Choose Without Media, then save the file to Files or AirDrop it to your computer.

In the demo, tap Choose file, or drop the file onto the phone. A .zip works too.

What happens to your chat.

It's read in this tab. The demo is the app itself, running in your browser, with the same engine that reads chats on the iPhone.

It's never uploaded. The page loads only its own files from this site and sends your chat nowhere. Its Content-Security-Policy lets it connect to this site only, and your browser enforces that.

Nothing is stored. No sign-up, no cookies, no local storage, no analytics. Close the tab and it's gone.

Check it yourself: open your browser's developer tools and watch the Network tab while a chat is read.

The rest is in the app.

The demo shows the free part that runs on your device. The reads by AI live in the Tellsy app for iPhone and Android.

18+. Tellsy reads patterns in text, for fun and self-reflection. It can't read minds. The sample chat is made up.
