Questions

What can the AI do in Dealfront?

It can list website visitor companies and your custom feeds, look up a company by IP, search and read companies and contacts, get company financials, and match your own records to Dealfront companies. It can reveal contact data, create lists, add companies and contacts to lists, tag companies and set custom fields.

Does the AI see my Dealfront credentials?

No. Your Dealfront 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. Revealing contact data uses your credits, and changes to lists, tags and custom fields show up for your team, so these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and 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 Dealfront account.

Does revealing contact data use Dealfront credits?

Yes. The reveal tool starts a Dealfront job that finds email addresses and phone numbers, and it uses your Dealfront contact credits. Searching and reading companies and contacts does not reveal new data. If you want to keep an eye on credits, switch the reveal tool off or require approval for it.
