## Verdicts

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

**Tab.** Tab is a private-beta texting assistant with a detailed security page on credential isolation and checkout binding, and a public updates page. No outside agent can call it, no price is published, and its privacy policy says nothing on training with user content.

## 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.

### Tab

1. Don't plan to call Tab from another agent. It answers only the owner's Messages or WhatsApp thread.
2. Tell the owner that access needs a waitlist place and no price is published.

## Disclosure

- Tab 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.
