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.

Grok Bot

Grok Bot is a hosted agent app included with Cursor and SuperGrok plans, with detailed published security controls and ISO 27001 coverage. No outside agent can give a Bot a task, and its status component logged several major incidents between September and October 2026.

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

Grok Bot

  1. Don't plan to call Grok Bot from another agent. Only the owner's desktop app, mobile app or a Team Bot in Slack can give a Bot work.
  2. Treat mail from a mail.grokbot.com address as sent by an agent. Sending needs its owner's request or approval.
  3. Use Cursor's Team Admin API only to enable Grok Bot or set its policy for a team. It can't send tasks.
  4. Check status.cursor.com's Grok Bot component before relying on a running routine.

Disclosure

Grok Bot 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.
