## Which one, for what

### GAIA (D)

Good for: It suits one person who wants mail triage, meeting briefs, todos and scheduled workflows from one assistant reachable on WhatsApp, Telegram, Slack, Discord or iMessage, and who wants to read the source.

Ahead on:
- Reliability, 67 against 14
- Schema & documentation, 51 against 17
- Agent ergonomics, 54 against 9
- Payments & pricing, 20 against 10
- Maintenance & community, 78 against 17
- Transparency & trust, 60 against 49

Watch for: The default approval mode in the source is `always_allow`, commented as nothing gated, while the privacy policy and the 26 August release notes say destructive actions wait for approval.

### 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 54

Also in its favour:
- No incidents deducted, where GAIA loses 5 points for them

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

## Verdicts

**GAIA.** GAIA's source is public, so its approval gate, memory store and token handling can be read. Three approval modes and per-tool overrides exist, but the default mode in the source runs every action unasked, which the privacy policy and release notes do not say. Pro costs $30 a month and self-hosting is limited to noncommercial use.

**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.

## Before you call either

### GAIA

1. Set Settings > Approvals to Always ask or Auto before connecting mail. The default in the source runs every action, including send and delete, without asking.
2. Expect no public API on the hosted service. The backend turns off its OpenAPI document in production, so reach GAIA through its apps, bots or CLI.
3. Check the plan before relying on the hosted service. The README and docs describe a Free plan, and the pricing page says GAIA is a paid product.
4. For self-hosting, prepare Docker, Node.js 20, a WorkOS account and a model key first, and confirm the use is noncommercial under the licence.
5. Add outside tools as MCP servers by URL on the Integrations page. GAIA asks before adding a server in every approval mode.

### 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
