Boba vs GAIA

Boba

Boba is a free texting assistant for one-to-one and group chats over iMessage, RCS and SMS, started by sending one message with no card or app. No outside agent can call it, its privacy notice uses inputs and outputs to train its models with no opt-out found, and no status page or security contact was found.

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.

Boba

1. Don't plan to call Boba from another agent. It answers only text messages in the Messages app.
2. Tell people in a group chat that messages sent to Boba may be used to train its models.

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.
