## Which one, for what

### Del (F)

Good for: People who want tasks, notes, reminders and Gmail handled by text on the channel they already use.

Ahead on:
- Reliability, 25 against 14
- Payments & pricing, 30 against 10
- Maintenance & community, 60 against 17
- Transparency & trust, 57 against 49

### Gemini Spark (F)

Good for: A person who already keeps mail, calendar and files in a personal Google Account and accepts Keep Activity being on.

Ahead on:
- Schema & documentation, 17 against 10
- Agent ergonomics, 9 against 0
- Security & auth, 60 against 0

Watch for: No public API, SDK or MCP server for an outside agent was found. Spark is reached in the Gemini mobile app, the Mac app and gemini.google.com

## 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.

**Gemini Spark.** Google's help pages state what Spark confirms before doing, how to delete its remote browser and code data, and the risks of prompt injection. Spark has no public API, Google calls it experimental, and it runs only with Keep Activity on, the setting under which chats are used for model training and human review.

## Before you call either

### Del

1. Don't plan to call Del from another agent. It answers only the owner's messaging threads and web workspace.
2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro.

### Gemini Spark

1. Do not plan an integration against Spark. No public API or MCP server was found, and a person must hold a Google AI Pro or Ultra subscription
2. Expect a confirmation request before sends, edits, purchases and web form submissions, and note that bulk changes to private Google Tasks run without one
3. Delete remote browser data and remote code execution data in Gemini Spark Settings after a sensitive session. Deleting a task thread or Gemini Apps activity does not remove them
4. Keep within 15 running tasks and 50 active schedules. A schedule does not run when 15 tasks are running or the usage limit is reached
5. Treat every safety statement here as Google's own description. None was tested, and no message was sent to the service

## 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.
