Watch for: Early access by access code only. ### Zo Computer (E) Good for: One person who wants a hosted assistant with its own Linux machine, reachable by text message and chat apps, and who accepts that the assistant acts on connected accounts without a documented approval step.

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. **Zo Computer.** Zo publishes an OpenAPI file, Markdown docs, plan prices and a named list of the providers that receive user content. One access token grants full access to the workspace, no approval step before sending or buying was found in the reviewed docs, and no status page, rate limit or SLA is published. ## Before you call either ### 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. ### Zo Computer 1. Send `POST https://api.zo.computer/zo/ask` with `Authorization: Bearer zo_sk_...` and an `input` string. The owner creates the token under Settings > Advanced 2. Pass `persona_id` for a persona with a narrow tool set. The token itself carries every permission the owner has 3. Set `memory_mode` to `off` to keep workspace memory out of a request. The field is in the OpenAPI file and absent from the API guide 4. Do not retry `/zo/ask` blindly after a timeout. No idempotency key is documented and the request may already have sent a message 5. Append `.md` to any guide or reference URL for Markdown ## Questions ### Which is better for AI agents, szn or Zo Computer? Zo Computer scores 43.1 (E) on agent readiness against szn's 7.3 (F), and leads in every scored category. ### Can an agent call szn and Zo Computer without installing anything? No hosted endpoint is listed for szn. Zo Computer has a hosted endpoint at https://api.zo.computer/mcp. ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/szn-vs-zo-computer.json, and with the fewest tokens: https://www.anchorterminal.com/compare/szn-vs-zo-computer.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "szn", "b": "zo-computer"}`.

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.
