Caddy vs Haven

Caddy

Caddy is a free iMessage and RCS assistant in public beta that watches connected mail, calendars and work apps and asks before sending email or changing data. No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two.

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.

Caddy

1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to.
2. Expect Caddy to ask the owner before it sends email or creates an invite.

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.
