Verdicts

Instinct

Instinct is a hosted assistant reached by text or call that acts in the owner's Google Workspace and WhatsApp and can make purchases. No outside agent can call it, no price is published, new sign-ups may meet a capacity waitlist, and materials train models unless the owner opts out.

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

Instinct

  1. Don't look for an endpoint. app.instinct.com/mcp serves the web app shell and refuses POST with 405.
  2. Confirm any purchase with the owner. The terms say Actions may not be reversible.

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.

Other comparisons with Instinct or Tab

Disclosure

Instinct 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.
