Verdicts

Hark Pro

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

Haven

Haven answers by phone call, text, email and app, is free in beta with no card, and publishes a status page with dated incidents. No public page read says which actions need approval, which accounts it connects or how their tokens are kept, and it names no model provider or sub-processor.

Before you call either

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.

Haven

  1. Haven has no documented API or MCP server. An outside agent can reach it only through the owner's channels (call, SMS, email, app).
  2. Do not assume an approval step before Haven sends mail, texts or calls. None is documented on the public pages.
  3. Email Haven sends to other people names Hello Haven as sender and says it was sent on the user's behalf, per the terms.
  4. Chat messages, history, profile context and uploaded files go to third-party AI model providers that the vendor does not name.
  5. Check status.hellohaven.ai before relying on phone or voice. All four published incidents affected those channels.
