Connect Claude & ChatGPT to Quentn

Ask your AI to look up a contact in Quentn, tag them, add a note or move a deal to the next stage. It can create contacts and opportunities, read your pipelines and stages, and look at your marketing emails. Contact and sales updates happen from the chat instead of the Quentn interface.

Questions

What can the AI do in Quentn?

The AI can search and read contacts, tags, notes, opportunities, pipelines, stages, lost reasons and marketing emails. It can create and update contacts, create tags, add and remove tags on contacts, add notes, and create, update and move opportunities.

Does the AI see my Quentn API key?

No. Your Quentn 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 read-only. Adding or removing tags can start automations tied to those tags, so those tools can require your approval before they run. The scopes on your Quentn API key also limit access. 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 Quentn account.

Why does HeyMyApps need my Quentn system address?

Each Quentn account runs at its own address, such as https://customer.eu-1.quentn.com. HeyMyApps needs it to send the API calls to your system. Copy it from the browser address bar when you are logged in.
