Questions

What can the AI do in KnowFirst?

The AI can search businesses and people, read business overviews, locations, people, news, jobs, tech stack, customer reviews, social profiles and related businesses, and look up people by ID or email. It can list your tracked businesses, feed events, suggestions and saved lists, create lists, add businesses and people to them, and track a business.

Does the AI see my KnowFirst API key?

No. Your KnowFirst credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with lookups only. Creating lists, adding to lists and tracking businesses can require your approval before they run. None of the tools delete anything. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own KnowFirst account, and the credits your requests use are between you and KnowFirst.

Does using KnowFirst through the AI spend credits?

Yes. Each request spends credits from your KnowFirst account balance, just like any other use of the KnowFirst API. The AI can read your account with its credit balance information, so you can keep an eye on it.
