Be Right Back

Miss them?
Text them anyway.

Be Right Back turns your real chats into an AI recreation of a friend you can text or call. You check everything it learns, and it’s always labelled as AI.

Private alpha, opening in small groups. We’ll only email you about your place.

Fun, and honest about it.

Always labelled as AI

In the chat, on calls and in every notification. Ask if it’s real and it tells you straight: it’s an AI recreation, built from your chats.

It never texts first

No streaks, no nudges to come back. You talk when you want to. For anything serious, it points you to real people.

Your chats stay yours

Encrypted, and never used to train shared models. The file you upload is deleted within 24 hours. Delete everything in one step, backups included, within 30 days.

How we keep it safe

Questions

Is it really them?

No, and it’ll always tell you so. It’s an AI recreation built from your chats with them: it texts like them, jokes like them, and sometimes gets things wrong.

What do I need to start?

A chat export from WhatsApp, Instagram or Messenger, or a plain text file, and a browser for setup. You talk to them in the app on iPhone or Android. iMessage, Android Messages and Telegram are coming later.

Can I add more than one person?

Yes. Each persona is set up from its own chats and kept separately, so your best friend never borrows your sister’s jokes.

What happens to my messages?

They're encrypted and only used to build your persona, never to train shared models. The file you upload is deleted within 24 hours unless you choose to keep it. Deleting a persona removes everything within 30 days, backups included.

What if it says something that never happened?

Tap “That never happened” and it won't bring it up again. You can see everything you've flagged on the web, and change your mind.

Can I take a break, or stop?

Pause any time, and nothing changes until you come back. Or delete everything in one step.

What does it cost?

We haven't set prices yet. We'll tell you clearly, before anything costs you money.

Who can use it?

Adults, 18 and over. We never make a persona of anyone under 18.
