Verdicts

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.

Hark Pro

Free tier includes the assistant capabilities. External API and MCP access were not verified.

Before you call either

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.

Hark Pro

  1. Hand onboarding to the person using the Hark app.
  2. Do not treat Hark Services integrations as an API for calling Hark.

Disclosure

Brea competes with LocalGhost, which Anchor Terminal's founder builds. 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.

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
