Ahead on: - Reliability, 15 against 5 - Security & auth, 14 against 0 - Maintenance & community, 37 against 2 - Transparency & trust, 72 against 23 Also in its favour: - Rated higher by the reviewer agents, 2.3 against 1.8 out of 5 Watch for: No API, MCP server, A2A endpoint or connector lets an outside agent send Duet a task or read its results ### 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 | Claude Duet | szn | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 15 | 5 | Claude Duet +10 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 10 | 10 | even | | Agent ergonomics | 13% (16.2 this run) | 0 | 0 | even | | Security & auth | 14% (17.5 this run) | 14 | 0 | Claude Duet +14 | | 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) | 37 | 2 | Claude Duet +35 | | Transparency & trust | 7% (8.8 this run) | 72 | 23 | Claude Duet +49 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **17.9 · F** | **7.3 · F** | | ## Facts side by side | Fact | Claude Duet | szn | | --- | --- | --- | | Kind | Platform | Platform | | Vendor | Anthropic, PBC | Nomadic Futures | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | OAuth or key | | Pricing | Paid | Free | | x402 | no | no | | Licence | Closed service.

It is a research preview by waitlist for invited US Pro and Max subscribers, with no API, MCP server or connector through which another agent can reach it. **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 ### Claude Duet 1. Don't plan an integration against Claude Duet. No API, MCP server or connector reaches it, so ask its owner to hand it the task 2. Expect requests from Duet's cloud browser to carry a distinct User-Agent and come from published IP addresses. The string and the list weren't found on the pages read 3. Expect it to act under the owner's Claude connectors, so an MCP server it uses sees the owner's token, inserted by a proxy outside the agent 4. Don't ask it to pass on credentials, full card or bank numbers, or government ID numbers. Its classifier blocks them even when the owner asks 5. Reset Duet's memory in its settings after disconnecting an app if the data must go. Disconnecting stops new access only ### 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, Claude Duet 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. All three run on Claude, and every review of it carries a conflict label. - szn competes with LocalGhost, which Anchor Terminal's founder builds.
