What's this about?
simonw keeps discovering undocumented capabilities in ChatGPT Work (the agent feature in OpenAI's mobile/web app): it has its own browser and can take screenshots with it, and it can deploy web apps to Cloudflare Workers under a feature called "ChatGPT Sites."
What exactly is "ChatGPT Work"?
It's OpenAI's in-app agent mode — you give it a task and it works in the background with tools (files, browser, code) rather than just chatting. Confusingly, there's a same-named but different mode in the desktop app. The notable part: it doesn't just write code, it can publish the result to the web (via Cloudflare's hosting) — prompt to live URL without you touching a deploy pipeline.
Why it matters
Chat products are quietly absorbing the whole build-and-ship loop: browser, coding, hosting. If a chatbot can deploy working web apps, a chunk of "no-code tools" and simple-website work is now a prompt away.
