Verdicts

Atticus

Atticus runs a person's Mac by voice on their existing Claude or Devin plan, with a sandboxed safe mode and a local log of every command. 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.

Orbits

Orbits is a family household app whose assistant, Bit, runs shared calendars, lists and meals, reads household email and places restaurant calls after approval, with iOS releases every week or two. No outside agent can call it, prices appear only as App Store in-app purchases, and no status page, security contact or named subprocessors were 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

Orbits

  1. Don't plan to call Orbits from another agent. llms.txt says no public agent API is offered.
  2. Tell the owner the assistant needs an Orbits subscription bought in the app, and that any trial appears only at purchase.

Disclosure

Orbits 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.
