## Verdicts

**Del.** Del is a hosted texting assistant and task workspace across iMessage, WhatsApp, Telegram, SMS, Discord and Slack, with a near-daily public changelog and a card-free 14-day trial. No outside agent can call it, no status page or security contact was found, and recent updates let some email actions skip approval.

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

## Before you call either

### Del

2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro.

### 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

- Del 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.
