Watch for: No API, MCP server or A2A endpoint for an outside agent. ### OpenDuet (D) Good 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: - Reliability, 42 against 25 - Schema & documentation, 58 against 10 - Agent ergonomics, 52 against 0 - Security & auth, 59 against 3 Also in its favour: - Open source Watch for: No release, tag, published image or deploy guide; the README marks it early development ## Score by category | Category | Weight | folk | OpenDuet | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 25 | 42 | OpenDuet +17 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 10 | 58 | OpenDuet +48 | | Agent ergonomics | 13% (16.2 this run) | 0 | 52 | OpenDuet +52 | | Security & auth | 14% (17.5 this run) | 3 | 59 | OpenDuet +56 | | Payments & pricing | 10% (12.5 this run) | 30 | 30 | even | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 35 | 37 | OpenDuet +2 | | Transparency & trust | 7% (8.8 this run) | 66 | 68 | OpenDuet +2 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **19.7 · F** | **49.5 · D** | | ## Facts side by side | Fact | folk | OpenDuet | | --- | --- | --- | | Kind | Platform | Agent harness | | Vendor | Nozomio, Inc. | CopilotKit (Tawkit, Inc.) | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | OAuth or key | | Pricing | Freemium | Freemium | | x402 | no | no | | Licence | Closed service under folk's terms (Nozomio, Inc., last updated 8 September 2026). | MIT.

No outside agent can call it, no status page or changelog was found, and its llms.txt and pricing file disagree on free limits and Max's price. **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 ### folk 1. Don't plan to call folk from another agent. It answers only the owner's iMessage, Telegram or WhatsApp thread and iPhone app. 2. Quote limits and prices from pricing.md and the terms, and note that llms.txt gives different free-tier limits. ### 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. ## Questions ### Which is better for AI agents, folk or OpenDuet? OpenDuet scores 49.5 (D) on agent readiness against folk's 19.7 (F), and leads in 6 of 7 scored categories. ### Are folk and OpenDuet open source? No open-source release is listed for folk. OpenDuet is open source (MIT. Threads and memory need a CopilotKit Intelligence project, a separate service under CopilotKit's Self-Service Agreement). ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/folk-nozomio-vs-openduet.json, and with the fewest tokens: https://www.anchorterminal.com/compare/folk-nozomio-vs-openduet.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "folk-nozomio", "b": "openduet"}`.

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. --- Query this catalogue directly over MCP: https://www.anchorterminal.com/mcp (Streamable HTTP, no key).
