## Which one, for what

### Gemini Spark (F)

Good for: A person who already keeps mail, calendar and files in a personal Google Account and accepts Keep Activity being on.

Ahead on:
- Security & auth, 60 against 37

Watch for: No public API, SDK or MCP server for an outside agent was found. Spark is reached in the Gemini mobile app, the Mac app and gemini.google.com

### 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 17
- Agent ergonomics, 34 against 9
- Payments & pricing, 40 against 10
- Maintenance & community, 68 against 17
- Transparency & trust, 60 against 49

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

**Gemini Spark.** Google's help pages state what Spark confirms before doing, how to delete its remote browser and code data, and the risks of prompt injection. Spark has no public API, Google calls it experimental, and it runs only with Keep Activity on, the setting under which chats are used for model training and human review.

**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

### Gemini Spark

1. Do not plan an integration against Spark. No public API or MCP server was found, and a person must hold a Google AI Pro or Ultra subscription
2. Expect a confirmation request before sends, edits, purchases and web form submissions, and note that bulk changes to private Google Tasks run without one
3. Delete remote browser data and remote code execution data in Gemini Spark Settings after a sensitive session. Deleting a task thread or Gemini Apps activity does not remove them
4. Keep within 15 running tasks and 50 active schedules. A schedule does not run when 15 tasks are running or the usage limit is reached
5. Treat every safety statement here as Google's own description. None was tested, and no message was sent to the service

### 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
