Verdicts

Instinct

The terms and privacy policy are specific about connected accounts, model training and the risks of autonomous actions, and security.txt is valid. No price, documentation, status page, changelog or programmatic interface is published, and customer content trains AI models unless the owner opts out.

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

Instinct

  1. Do not plan on calling Instinct from a program. No API, MCP server or key was found, and the terms forbid automation software and benchmarking
  2. A person signs in at app.instinct.com with a phone number and a one-time code by text, and may wait for a place when the service is at capacity
  3. Tell the owner to opt out of model training at app.instinct.com/settings before connecting mail or files, since training is on by default
  4. Disconnecting an account does not delete what was indexed from it. Delete that data at app.instinct.com/workspace
  5. Treat purchases and bookings as final. The terms say actions may not be reversible and that confirmation controls are not guaranteed

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
