Custom GPT

A Custom GPT is a version of ChatGPT you shape with your own instructions, knowledge files, and a name — a no-code assistant anyone can spin up inside ChatGPT. Think of it as a branded chat persona: it answers in your voice and can pull from documents you upload, but everything still comes back as text.

That last part is the catch. A Custom GPT talks. A ChatGPT app does. An app renders an interactive surface right inside the conversation — a real interface where someone can pick, fill, and book — while a Custom GPT can only describe the next step and hope the person leaves to take it.

Why it matters for the ChatGPT funnel

A Custom GPT can get you found and even liked. It cannot close. When a buyer reaches real intent and is ready to move, a text-only assistant hands them a link and waits — and most of that pipeline leaks. The gap between "this brand sounds great" and "I booked a call" is exactly where deals fall out of the ChatGPT funnel. Knowing which one you have tells you whether you're built to convert or just to converse.

How drio fits

drio runs on the app side of that line. Instead of a persona that answers questions, you get an interface the assistant picks at the moment of intent — one that captures the lead and books the meeting without the buyer ever leaving the chat. The conversation becomes the conversion, not just a pointer to one.
