It has no API, MCP server or documented command for another agent, it is five days old, and it rebuilds itself from the main branch every six hours by default. **Brea.** Brea is an iMessage assistant with a free plan that needs no card, approval by reply before it sends, deletes or pays, and one-time Link cards for purchases. No outside agent can call it, paid prices sit inside the app, and no changelog or subprocessor list was found. ## Before you call either ### Atticus 1. Don't plan to call Atticus from another agent. It takes requests only from its own shortcut and typing box 2. If a user runs Atticus beside you, expect it to move windows and type into apps on the same Mac 3. Point a user who wants pinned versions to Settings > About & Updates to turn off self-update ### Brea 1. Don't plan to call Brea from another agent. It answers only the owner's iMessage thread. 2. Tell the owner that replying ALWAYS stops Brea asking again for that action. ## Questions ### Which is better for AI agents, Atticus or Brea?

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
