## Which one, for what

### Tab (F)

Good for: A person who wants a texting assistant that browses, calls and buys with tight checkout controls.

Watch for: Private beta behind a waitlist.

### 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:
- Reliability, 15 against 5
- Schema & documentation, 73 against 0
- Agent ergonomics, 34 against 0
- Security & auth, 37 against 4
- Payments & pricing, 40 against 0
- Maintenance & community, 68 against 58
- Transparency & trust, 60 against 45

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

**Tab.** Tab is a private-beta texting assistant with a detailed security page on credential isolation and checkout binding, and a public updates page. No outside agent can call it, no price is published, and its privacy policy says nothing on training with user content.

**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

### Tab

1. Don't plan to call Tab from another agent. It answers only the owner's Messages or WhatsApp thread.
2. Tell the owner that access needs a waitlist place and no price is published.

### 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

## Disclosure

- Tab 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.
