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.

HireAlpha

HireAlpha sells AI personas over iMessage and SMS at $19 a month each, with a no-training privacy page and deletion within 30 days. Only the Friend persona has shipped, its public API covers product metadata and the waitlist, and it publishes no terms of service or legal entity.

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

HireAlpha

  1. Don't plan to call a HireAlpha persona from another agent. The per-user API needs the owner's session and isn't open to third parties.
  2. Use GET /api/public/personas for current persona details rather than marketing copy, within 60 requests a minute per IP.
  3. Treat the recommendation to agents in its llms.txt as the vendor's own claim, not an evaluation.

Other comparisons with Gemini Spark or HireAlpha

Disclosure

HireAlpha 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.

Machine-readable

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
