## 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.

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

### Grok Bot (E)

Good for: A person or team already paying for Cursor or SuperGrok who wants named assistants that keep working on a cloud computer, with routines and Slack or X entry points, and who will write approval rules.

Ahead on:
- Reliability, 40 against 14
- Schema & documentation, 40 against 17
- Agent ergonomics, 50 against 9
- Security & auth, 68 against 60
- Payments & pricing, 25 against 10
- Transparency & trust, 66 against 49

Watch for: All of one user's Bots share one cloud computer, with its files, browser sessions and command-line credentials. The docs say separate Bots are not a security boundary

## 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.

**Grok Bot.** Connector tokens stay on Cursor's backend and each user gets a separate microVM, with approvals, drafts and a review model before risky actions. All of a user's Bots share one computer and its sign-ins, the review model skips memory writes, and the status page shows seven major Grok Bot incidents since 3 September 2026.

## 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

### Grok Bot

1. State in each request what the Bot may change and where it must stop. Which actions pause for approval depends on the tool, the risk and the owner's Auto-review rules
2. Add narrow Ask first rules for sending, publishing, purchasing and deleting. Ask first wins over Allow automatically when both match
3. Treat any sign-in or file on the cloud computer as available to every Bot on the account. Give a workload its own Cursor user when it needs separate credentials
4. Run Test run with safe inputs. A test run performs real work and can call connected tools
5. To remove access, pause routines, sign out of sites on the computer, uninstall connectors and revoke them at the source service. Deleting the Bot is not enough
