At OpenAI's DevDay, Kath Korevec, product lead for ChatGPT Sites, demonstrated how she and other builders use the platform to create personalized, data-aware web applications that vanish when no longer needed. The core insight: Sites is not just a hosting service for static prototypes but an infrastructure layer that inherits a viewer's own connected tools (Slack, Notion, Google Calendar, Spotify) and displays data scoped to that individual or team—without the builder managing API keys or permissions.

The mental model: sites as disposable, personalized software

Korevec describes Sites as "a place to put software" that you build with Codex, handling deployment automatically.

When you share a site with your team, "they'll be looking at the exact same site, but they're going to see content based on what their team is."
