## Which one, for what

### 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:
- Security & auth, 60 against 49
- Maintenance & community, 17 against 9

Also in its favour:
- No incidents deducted, where Lindy loses 3 points for them

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

### Lindy (F)

Good for: Lindy suits a person or small team that lives in Slack and Google or Microsoft mail and wants briefs, drafts, scheduling and meeting notes done on a schedule.

Ahead on:
- Reliability, 24 against 14
- Schema & documentation, 32 against 17
- Agent ergonomics, 43 against 9
- Payments & pricing, 35 against 10

Also in its favour:
- Free to start without a card

Watch for: The integrations page says approval settings apply in shared Slack threads only. Web chat, Slack direct messages, iMessage and SMS are not covered, and reads are never covered.

## Verdicts

**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.

**Lindy.** Lindy keeps what it remembers in files the owner can read and edit, and publishes credit prices. Its approval setting applies in shared Slack threads only, so writes asked for by direct message, text or web chat run unasked, which its pricing page does not say. It has no status page, and its changelog stops in October 2025.

## Before you call either

### 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

### Lindy

1. Treat a request sent by direct message, text or web chat as unguarded. Approval prompts appear in shared Slack threads only.
2. Run a routine as a dry run before turning it on. A dry run reads real data and sends, posts and writes nothing.
3. Turn off unused tools after adding an MCP server. Every supported tool arrives switched on, and a large server adds more than a hundred.
4. Expect a billed seat for anyone who mentions Lindy in Slack. A teammate who joins that way has seven free days first.
5. Connect only hosted MCP servers on public HTTPS with streamable HTTP, the one kind the docs describe.
