## Which one, for what

### Claude Duet (F)

Good for: A US Pro or Max subscriber who runs work or a small business through connected apps such as Gmail, Google Calendar, QuickBooks, Stripe, Gusto and HubSpot and wants a morning brief and approved actions.

Ahead on:
- Transparency & trust, 71 against 52

Also in its favour:
- No incidents deducted, where DeepTutor loses 3 points for them

Watch for: No API, MCP server, A2A endpoint or connector lets an outside agent send Duet a task or read its results

### DeepTutor (B)

Good for: A learner, a teacher or a small group that wants a self-hosted tutor over their own documents, with quizzes, research reports, memory and IM companions, or for an agent that hands study tasks to it through the JSON CLI.

Ahead on:
- Reliability, 78 against 15
- Schema & documentation, 71 against 10
- Agent ergonomics, 63 against 0
- Security & auth, 51 against 14
- Payments & pricing, 60 against 10
- Maintenance & community, 84 against 37

Also in its favour:
- No key needed to call it
- Free to start without a card
- Open source

Watch for: The default launch binds the backend to 0.0.0.0 with sign-in off and CORS open to any origin with credentials

## Verdicts

**Claude Duet.** Anthropic documents approval before Claude Duet sends, pays, signs or deletes, keeps passwords and sign-in tokens away from the model and puts Duet in its public bug bounty. 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.

**DeepTutor.** DeepTutor runs on the owner's machine under Apache 2.0, ships releases every few days with upgrade notes, and gives other agents a JSON CLI with resumable sessions. Its default launch binds all interfaces with sign-in off and permissive CORS, there is no security policy, and two CVEs in 2026 covered a shell-tool RCE and a multi-user MCP bypass, both fixed.

## 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

### DeepTutor

1. Run `deeptutor run <capability> "..." --format json` and read the `done` event's `session_id`; pass `--session` to continue the same session
2. Configure with `deeptutor config apply setup.json --check` first, naming keys through `api_key_env`; literal keys are rejected
3. Before exposing it beyond one machine, enable sign-in in `auth.json`, set exact `cors_origins` and set `BACKEND_HOST=127.0.0.1` where loopback is wanted
4. Run 1.4.10 or later. Earlier versions carry CVE-2026-51870 (shell tool RCE, fixed in 1.4.1) and CVE-2026-58168 (multi-user MCP bypass)
5. Set `sandbox_allow_subprocess` to false where generated code must run only in the runner sidecar or bubblewrap

## Disclosure

- Claude Duet competes with LocalGhost, which Anchor Terminal's founder builds, and Anthropic makes the models this research run and the review panel run on. 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.
