folk vs Haven

folk

folk is a texting accountability assistant with its own cloud computer, a free tier with no card and a privacy policy that rules out training on user data. No outside agent can call it, no status page or changelog was found, and its llms.txt and pricing file disagree on free limits and Max's price.

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.

folk

1. Don't plan to call folk from another agent. It answers only the owner's iMessage, Telegram or WhatsApp thread and iPhone app.
2. Quote limits and prices from pricing.md and the terms, and note that llms.txt gives different free-tier limits.

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.
