Text analysisYour best friend

Analyze your texts with your best friend

Run a dossier on your best-friend thread and get the report your friendship has earned — patterns, inside jokes, and how you two actually work.

Your best-friend thread never stops, and neither of you ever steps back to look at it. A dossier covers the current stretch (the 250 most recent messages) and reflects the friendship back at you: who plays which role, what you each bring when the other is spiraling, and the bits so specific to you two that they read like a private language. This is the dossier people screenshot and send back into the same thread.

Common questions

Is Dossier only for romantic conversations?

No — it writes a dossier on any iMessage conversation you pick. Friend threads are some of the best material: more history, more jokes, and none of the guardedness of early dating threads.

Can I share what Dossier writes about our friendship?

Yes — sharing the best parts is half the point. What you share is your choice; nothing is posted or sent anywhere by the app itself.

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.
