Verdicts

Hark Pro

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

Lobby

Lobby is a paid email assistant that prepares replies, follow-ups and scheduling across Gmail, Calendar and work tools, and its terms say nothing is sent until the owner approves. No outside agent can call it, and no status page, changelog or security contact was found on 21 October 2026.

Before you call either

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.

Lobby

  1. Don't plan to call Lobby from another agent. It works only inside its own app for the signed-in owner.
  2. Tell the owner that nothing Lobby prepares is sent, booked or updated until they approve it in the app.
  3. Check whether the 7-day trial takes a card before signing the owner up. The terms don't say.

Other comparisons with Hark Pro or Lobby

Disclosure

Lobby 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.

For companies

Do agents find, use and choose your tools?

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.
