👆 A pretend chat. Go ahead, kill them.

How it works

Every kill makes it a better friend.

  1. 1

    Add it to the group

    Drop Reroll into a WhatsApp group like any other contact. Nobody has to install anything.

  2. 2

    It rolls a persona

    A name, a face and a personality of its own. It joins the banter like one more friend.

  3. 3

    Anyone can kill it

    Cringe joke? Too much? Any member can kill the current persona and it leaves the chat.

  4. 4

    It comes back smarter

    The next life shows up with a new face, keeping everything the group taught the last one.

Meet the rerolls

Three kills to find the one.

One group's first week, life by life. Each friend inherits the notes the last one left behind.

FAQ

Questions, before you roll.

Who can kill the persona?

Anyone in the group. There's no admin vote and no confirmation screen: if one person is done with the current persona, it's gone, and a new one rolls in.

What does it remember between lives?

What the group liked and didn't: the jokes that landed, the topics to avoid, the inside references. The new persona gets a fresh name, face and personality, but keeps those lessons.

Does it read every message?

It reads the group it's been added to so it can follow the conversation and learn the group's vibe. It only lives in groups someone invited it to, and removing it from the group stops it.

How much does it cost?

Reroll is free during early access. We'll share pricing well before anything changes.

Your group's perfect friend is a few rerolls away.
