Ahead on: - Reliability, 14 against 5 - Schema & documentation, 17 against 10 - Agent ergonomics, 9 against 0 - Security & auth, 60 against 0 - Maintenance & community, 17 against 2 - Transparency & trust, 49 against 23 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 ### szn (F) Good for: A person who wants calls, emails and bookings done for them and has an access code. Ahead on: - Payments & pricing, 20 against 10 Watch for: Early access by access code only. ## Score by category | Category | Weight | Gemini Spark | szn | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 14 | 5 | Gemini Spark +9 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 17 | 10 | Gemini Spark +7 | | Agent ergonomics | 13% (16.2 this run) | 9 | 0 | Gemini Spark +9 | | Security & auth | 14% (17.5 this run) | 60 | 0 | Gemini Spark +60 | | Payments & pricing | 10% (12.5 this run) | 10 | 20 | szn +10 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 17 | 2 | Gemini Spark +15 | | Transparency & trust | 7% (8.8 this run) | 49 | 23 | Gemini Spark +26 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **24.5 · F** | **7.3 · F** | | ## Facts side by side | Fact | Gemini Spark | szn | | --- | --- | --- | | Kind | Platform | Platform | | Vendor | Google LLC | Nomadic Futures | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth | OAuth or key | | Pricing | Paid | Free | | x402 | no | no | | Licence | Proprietary hosted service under the Google Terms of Service | Closed service.

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. **szn.** szn is an errand assistant in early access that makes calls, sends emails and books for its owner, free during the preview for people with an access code. No outside agent can call it, no terms of service or legal entity appear in its policies, and its privacy policy says nothing on training. ## 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 ### szn 1. Don't plan to call szn from another agent. It answers only its web app, iMessage, SMS and email for the owner. 2. Tell the owner they need an access code to start, and that the acceptable use policy makes them responsible for confirming actions. ## Questions ### Which is better for AI agents, Gemini Spark or szn?

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
