## Which one, for what

### Haven (F)

Good for: A consumer assistant for one person who wants to phone, text or email it and have it remember them.

Ahead on:
- Reliability, 35 against 15

Watch for: No approval setting or list of actions that need confirmation was found on the public pages. The terms say it sends emails, SMS and calls following the user's instructions.

### 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.

Ahead on:
- Schema & documentation, 73 against 4
- Agent ergonomics, 34 against 6
- Security & auth, 37 against 13
- Payments & pricing, 40 against 30
- Maintenance & community, 68 against 35
- Transparency & trust, 60 against 51

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: The access token for the API and MCP endpoint grants full access to the workspace, with no scoped or read-only token documented

## 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
