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.

Hark Pro

Free tier includes the assistant capabilities. External API and MCP access were not verified.

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.

Hark Pro

  1. Hand onboarding to the person using the Hark app.
  2. Do not treat Hark Services integrations as an API for calling Hark.
