Brief on Mobile

Chat with Brief from your phone's browser on iOS or Android, or install the iOS TestFlight app for voice — with document, decision, and digest links opening straight into chat.

Last updated: July 5, 2026

Brief on mobile puts your Navigator in your pocket — chat with Brief and talk through decisions from wherever you are.

Availability

Open Brief in your phone's browser and it switches to a mobile-friendly layout automatically — no install required, on iOS or Android. Sign in with the same account you use on the web.

For a dedicated app with voice, join the iOS beta through TestFlight, Apple's beta testing program.

Mobile is in active beta. Expect the core chat experience to be solid, with some capabilities still desktop-only (see below).

Chat, wherever you are

Mobile chat carries the same conversation as web: multi-turn context, contextual preset prompts, and the same tool calls Brief runs on your product graph and connected tools. Start a thread on your phone and pick it back up on desktop — conversation history is shared across surfaces.

Voice

In the TestFlight app, you can talk to Brief instead of typing. Ask a question out loud and Brief responds in a live conversation, with the same tool calls and reasoning happening underneath as in a typed chat — you just experience it as speech.

When you tap a document or decision link — from Slack, email, or your weekly digest — it opens directly into a mobile-friendly chat view instead of a full editor. You can read the content and ask Brief about it right there.

Your weekly digest works the same way: opening it from your inbox drops you into a chat about that digest, and that conversation stays in your history so you can find it again later.

What's different from desktop

A few things are still desktop-only while mobile is in beta:

  • Full document editing — mobile shows document content inside chat; editing happens on desktop.
  • Landscape layout — the TestFlight app is portrait-only for now.
