## Which one, for what

### GAIA (D)

Good for: It suits one person who wants mail triage, meeting briefs, todos and scheduled workflows from one assistant reachable on WhatsApp, Telegram, Slack, Discord or iMessage, and who wants to read the source.

Ahead on:
- Reliability, 67 against 42
- Maintenance & community, 78 against 37

Watch for: The default approval mode in the source is `always_allow`, commented as nothing gated, while the privacy policy and the 26 August release notes say destructive actions wait for approval.

### 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:
- Schema & documentation, 58 against 51
- Security & auth, 59 against 54
- Payments & pricing, 30 against 20
- Transparency & trust, 68 against 62

Also in its favour:
- Free to start without a card
- Open source
- No incidents deducted, where GAIA loses 5 points for them

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

## Verdicts

**GAIA.** GAIA's source is public, so its approval gate, memory store and token handling can be read. Three approval modes and per-tool overrides exist, but the default mode in the source runs every action unasked, which the privacy policy and release notes do not say. Pro costs $30 a month and self-hosting is limited to noncommercial use.

**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

### GAIA

1. Set Settings > Approvals to Always ask or Auto before connecting mail. The default in the source runs every action, including send and delete, without asking.
2. Expect no public API on the hosted service. The backend turns off its OpenAPI document in production, so reach GAIA through its apps, bots or CLI.
3. Check the plan before relying on the hosted service. The README and docs describe a Free plan, and the pricing page says GAIA is a paid product.
4. For self-hosting, prepare Docker, Node.js 20, a WorkOS account and a model key first, and confirm the use is noncommercial under the licence.
5. Add outside tools as MCP servers by URL on the Integrations page. GAIA asks before adding a server in every approval mode.

### 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, GAIA or OpenDuet?

GAIA and OpenDuet score within a point of each other on agent readiness, 49.7 (D) and 49.5 (D). OpenDuet leads on schema & documentation, security & auth, payments & pricing and transparency & trust.

### Are GAIA and OpenDuet open source?

No open-source release is listed for GAIA. OpenDuet is open source (MIT. Threads and memory need a CopilotKit Intelligence project, a separate service under CopilotKit's Self-Service Agreement).
