## Which one, for what

### 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 15
- Agent ergonomics, 52 against 34
- Security & auth, 59 against 37
- Transparency & trust, 68 against 61

Also in its favour:
- Free to start without a card
- Open source

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

### Zo Computer (E)

Good for: One person who wants a hosted assistant with its own Linux machine, reachable by text message and chat apps, and who accepts that the assistant acts on connected accounts without a documented approval step.

Ahead on:
- Schema & documentation, 73 against 58
- Payments & pricing, 40 against 30
- Maintenance & community, 68 against 37

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: The access token for the API and MCP endpoint grants full access to the workspace, with no scoped or read-only token documented

## Verdicts

**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.

**Zo Computer.** Zo publishes an OpenAPI file, Markdown docs, plan prices and a named list of the providers that receive user content. One access token grants full access to the workspace, no approval step before sending or buying was found in the reviewed docs, and no status page, rate limit or SLA is published.

## Before you call either

### 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.

### Zo Computer

1. Send `POST https://api.zo.computer/zo/ask` with `Authorization: Bearer zo_sk_...` and an `input` string. The owner creates the token under Settings > Advanced
2. Pass `persona_id` for a persona with a narrow tool set. The token itself carries every permission the owner has
3. Set `memory_mode` to `off` to keep workspace memory out of a request. The field is in the OpenAPI file and absent from the API guide
4. Do not retry `/zo/ask` blindly after a timeout. No idempotency key is documented and the request may already have sent a message
5. Append `.md` to any guide or reference URL for Markdown
