Connect Claude & ChatGPT to Coresignal

Ask your AI to find companies, people or job postings in Coresignal data and get full profiles back. It can search with filters or a plain-language description, enrich a company from its website or a person from their LinkedIn URL, and read a company's headcount history and posts. Research that used to take several searches becomes one question.

Questions

What can the AI do in Coresignal?

It can search companies, employees, jobs and company posts with filters or a plain-language prompt, read full and multi-source profiles, read a company's headcount history, and enrich companies from a website or social URL and people from a LinkedIn URL.

Does the AI see my Coresignal API key?

No. Your Coresignal API key is encrypted at rest and never shown to the AI. After you save it, it is 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, for example company tools without employee lookups. All Coresignal tools search and read data, and none of them change anything. 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, and you do not need a credit card to start. Paid plans are billed per completed task. You also need your own Coresignal account, and anything Coresignal charges is between you and Coresignal.

What is the difference between a profile and a multi-source profile?

A profile comes from one Coresignal dataset. A multi-source profile combines data from several sources into one record. The AI can get either for companies and employees.
