No public page read says which actions need approval, which accounts it connects or how their tokens are kept, and it names no model provider or sub-processor. **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 ### Haven 1. Haven has no documented API or MCP server. An outside agent can reach it only through the owner's channels (call, SMS, email, app). 2. Do not assume an approval step before Haven sends mail, texts or calls. None is documented on the public pages. 3. Email Haven sends to other people names Hello Haven as sender and says it was sent on the user's behalf, per the terms. 4. Chat messages, history, profile context and uploaded files go to third-party AI model providers that the vendor does not name. 5. Check status.hellohaven.ai before relying on phone or voice. All four published incidents affected those channels. ### 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, Haven or szn?

szn 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.
