## 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.

Also in its favour:
- No incidents deducted, where nanobot loses 6 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

### nanobot (B)

Good for: A technical owner who wants an assistant on their own machine across many chat apps, with file-based memory and a free choice of model.

Ahead on:
- Reliability, 70 against 14
- Schema & documentation, 77 against 17
- Agent ergonomics, 74 against 9
- Payments & pricing, 60 against 10
- Maintenance & community, 82 against 17

Also in its favour:
- No key needed to call it
- Open source

Watch for: No per-action approval was found in the docs or source. The agent sends messages, runs shell commands and edits files without asking

## 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.

**nanobot.** nanobot runs on the owner's machine under the MIT licence, with no telemetry found in its source and memory kept as files the owner can read and restore. No per-action approval step was found, and the shell sandbox and workspace restriction are off by default. Five security advisories were published between March and September 2026, all with fixes.

## 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

### nanobot

1. Set `tools.restrictToWorkspace` to true and `tools.exec.sandbox` to `bwrap` or `seatbelt` before giving it real accounts. Both are off by default
2. Run 0.3.0 or later. Earlier versions carry the published SSRF flaw in web fetch (GHSA-vc5v-6vwm-wf9m)
3. Keep `allowFrom` narrow on every channel and never set `["*"]` on Email, which has no pairing
4. Write secrets as `${VAR}` references in `~/.nanobot/config.json`. Plain values are stored in clear text
5. Use `nanobot -m "..."` for a one-shot run, and keep `nanobot gateway` running for channels, schedules and heartbeat
