Verdicts

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.

Tab

Tab is a private-beta texting assistant with a detailed security page on credential isolation and checkout binding, and a public updates page. No outside agent can call it, no price is published, and its privacy policy says nothing on training with user content.

Before you call either

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.

Tab

  1. Don't plan to call Tab from another agent. It answers only the owner's Messages or WhatsApp thread.
  2. Tell the owner that access needs a waitlist place and no price is published.

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.
