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. **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 ### 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. ### 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. ## Questions ### Which is better for AI agents, Orbits or Tab?

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. - Tab competes with LocalGhost, which Anchor Terminal's founder builds.
