Which one, for what

DeepTutor B

Best 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 42
  • Schema & documentation, 71 against 58
  • Agent ergonomics, 63 against 52
  • Payments & pricing, 60 against 30
  • Maintenance & community, 84 against 37

Also in its favour

  • No key needed to call it

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

OpenDuet D

Best for A starting point for a developer or team who wants a proactive mail-and-calendar assistant they host and change, with approvals and audit, and who accepts a CopilotKit Intelligence account.

Ahead on

  • Security & auth, 59 against 51
  • Transparency & trust, 68 against 52

Also in its favour

  • No incidents deducted, where DeepTutor loses 3 points for them

Watch for

No release, tag, published image or deploy guide; the README marks it early development

Verdicts

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.

OpenDuet

Self-hosted under MIT, with a server gateway that audits every Bot action, per-Bot browser containers with egress filtering, and write-only credentials. Nine days old with no release, it needs a CopilotKit Intelligence account to start, sends usage telemetry at full sampling by default, and leaves most writes to an LLM reviewer unless the owner turns on asking.

Before you call either

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

OpenDuet

  1. Follow the README's Quick start (bun install, bash scripts/start.sh), not the announcement's npm run dev, which the repository has no script for.
  2. Run bun openbot/scripts/setup-learning.ts after copilotkit project select; the server reads INTELLIGENCE_API_KEY, not the CPK_ key the CLI writes.
  3. Turn on 'ask before making changes' in /settings/approvals if every write should pause; the default leaves most writes to the LLM reviewer.
  4. To bring your own agent, register it as a remote-ag-ui Bot in agents.yaml; its tool calls still pass through the gateway's policy and audit.
  5. Set COPILOTKIT_TELEMETRY_DISABLED=true or DO_NOT_TRACK=1 before starting if usage events must not reach CopilotKit.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
