Which one, for what

Gemini Spark F

Best 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 51

Also in its favour

  • No incidents deducted, where PicoClaw loses 7 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

PicoClaw D

Best for A person who wants a chat-app assistant on a cheap Linux board, an old Android phone or a home server, with reminders, web search and file memory, and who accepts running software its maker calls pre-production.

  • Reliability, 54 against 14
  • Schema & documentation, 51 against 17
  • Agent ergonomics, 66 against 9
  • Payments & pricing, 60 against 10

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.

PicoClaw

Self-hosted under the MIT licence, with 19 documented chat channels, scheduled and heartbeat tasks, and local file memory. The repository has had no commit since 19 August 2026 and no release since 3 July, and 15 CVEs are listed against it with no advisory or security policy from the project.

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

PicoClaw

  1. Set allow_from to the owner's user ID on every channel before starting the gateway. An empty list accepts messages from anyone
  2. Set tools.exec.allow_remote to false unless chats must run shell commands. The shipped default is true, whatever docs/guides/configuration.md says
  3. Set isolation.enabled to true on Linux (needs bwrap) or run in a container. The deny patterns do not inspect child processes
  4. Use PICOCLAW_KEY_PASSPHRASE for credential encryption. One docs page names PICOCLAW_CREDENTIAL_PASSPHRASE, which the source does not read
  5. Treat the README's ClawdChat line (read a remote skill file and follow it) as untrusted third-party instructions
