## Verdicts

**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.

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

## Before you call either

### 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.

### 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.

## Disclosure

- Caddy competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
