Jigsaw Open Jigsaw

The group chat that builds itself.

Every group's chat is its own app. Type @jigsaw and ask for anything: a league table, a countdown, a murder mystery, a whole new look. Once your group says yes, the whole chat changes.

Ask in the chat

Type @jigsaw like you would to a friend. Not quite right? Ask again and it tweaks the same change.

The group decides

Everyone tries a preview first. It goes live when the group approves, or when an admin says so.

Nothing is permanent

Go back to any earlier version from History. If something looks broken, safe mode shows the plain chat.

How it works

It starts as a normal group chat. Then it becomes whatever your group needs.

  1. Start a group

    Pick friends from your contacts, or share an invite link or QR code. It opens in the app or a browser, nothing to install.

  2. Ask for something

    "@jigsaw split the villa costs." Jigsaw builds it while you keep talking, and checks it before anyone sees it.

  3. Try it, then approve

    Everyone gets a preview. Your group picks who decides: everyone, or only admins. Changed your mind? Undo it.

Or start with a ready-made piece

One tap adds it to the top of your chat. Seen something great in another group? Copy it into yours. Their messages never come with it.

Yours, and only your group's

Each group's app runs on its own, kept apart from every other group and from the rest of the internet.

Private to the group

Only members see the messages, and the data your group's pieces keep stays inside the group.

Voice notes stay yours

Voice notes, photos and files are never sent to the AI.

Checked before you see it

Every change passes automatic checks and a safety review before the group gets a preview.

No ad trackers

No advertising and no outside analytics. Sign in with your phone number, no password to forget.

Free to start

Everyone gets free builds each month, to use in any of their groups. Small changes and ready-made pieces are always free. Want more? The group can top up together, so one keen person doesn't carry it.
