No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two. **szn.** szn is an errand assistant in early access that makes calls, sends emails and books for its owner, free during the preview for people with an access code. No outside agent can call it, no terms of service or legal entity appear in its policies, and its privacy policy says nothing on training. ## Before you call either ### Caddy 1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to. 2. Expect Caddy to ask the owner before it sends email or creates an invite. ### szn 1. Don't plan to call szn from another agent. It answers only its web app, iMessage, SMS and email for the owner. 2. Tell the owner they need an access code to start, and that the acceptable use policy makes them responsible for confirming actions. ## Questions ### Which is better for AI agents, Caddy or szn?

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