OpenAI Apps SDK: The New Browser Moment (www.nuefunnel.com)

OpenAI’s Apps SDK turns ChatGPT from a conversational agent into an in-chat app platform — you can now trigger and execute actions (bookings, purchases, productivity tasks) directly inside the conversation instead of being routed to external websites. Technically this relies on LLM-driven intent interpretation plus formalized app integrations that run across web, mobile and desktop. Unlike earlier, device-locked systems (Apple’s App Intents) or browser-automation attempts (Comet, Dia), the SDK creates an open, cross-platform conduit where thousands of third‑party apps can expose capabilities that the assistant calls to fulfill user requests. The shift is significant because it redefines value on the web: information becomes free and execution is premium. Transactional apps (travel, commerce, payments, productivity) gain new distribution, while attention-driven publishers and ad-supported sites risk losing traffic and monetization. It also concentrates power: OpenAI will influence discovery, pricing models, and data access, creating developer dependency and likely regulatory scrutiny. Practically, success hinges on developer adoption, app discovery/ranking inside the assistant, and trust mechanisms — meaning the emergent “execution economy” will prize reliability, transaction flows, and who controls the conversational surface as much as raw AI capability.
