Apps SDK
OpenAI's toolkit for building apps that run inside ChatGPT — the plumbing behind the apps your buyers see.
The Apps SDK is OpenAI's toolkit for building apps that run inside ChatGPT. It lets a developer define both what an app does and how it looks, so it can answer in plain language and show a working interface right inside the chat. Under the hood it builds on the Model Context Protocol, but for you the point is simpler: it's the plumbing behind the ChatGPT apps your buyers actually see and use.
Why it matters for the ChatGPT funnel
Your buyers are no longer clicking through to your site. They're asking ChatGPT, and increasingly the answer is an app they can act on without ever leaving the chat. The Apps SDK is what makes that possible. If you're not present as an app at the moment of intent, the assistant hands the buyer to whoever is. Showing up in the answer is no longer enough. Getting picked — and giving the buyer something they can book or buy on the spot — is where pipeline is won or lost now.
How drio fits
drio is the app you put at that moment. You don't have to wire up the SDK or the tool calls yourself — drio runs an app inside ChatGPT that gets picked when a buyer is ready, then books the meeting inside the conversation. It turns the demand you already earn in AI search into booked leads, so the visibility you've built actually converts into pipeline.
Win the answer, not just the ranking
drio turns the ChatGPT and Claude conversations your buyers are already having into booked calls. Build the app that gets you picked.
