Analyze your group chat with Dossier

Run a dossier on your group chat and see its characters, its dynamics, and the patterns everyone suspects but nobody has proof of.

A group chat is its own small society: the planner, the ghost, the one who replies to messages from four hours ago, the two members having a private conversation in public. A dossier covers the chat's recent run and names the dynamics — who drives it, what actually gets everyone talking, and what the group's energy runs on. It is the closest thing to minutes for a meeting that never ends.

Good to know

The sample group-chat dossier in the app (the Sunday group chat) shows the shape before you spend anything on your own: the cast, the dynamics, and the cards a group thread produces.

Common questions

Does Dossier work on group chats or only one-on-one threads?

Both. A group-chat dossier takes in the whole room: who drives conversations, what gets people talking, and the group's dynamics — alongside the same style cards a one-on-one dossier has.

Do the other members of the chat know?

No. Dossier never posts into the chat or contacts anyone — nothing changes in the thread itself. What you do with the dossier — including dropping it into the chat — is up to you.

A dossier is for fun and reflection, not advice. It surfaces patterns in how people text each other — it does not diagnose anyone, and nothing it writes is a finding of fact about another person. What leaves your Mac and what never does is set out in how Dossier protects your data.
