Verdicts

Haven

Haven answers by phone call, text, email and app, is free in beta with no card, and publishes a status page with dated incidents. 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.

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

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.

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
