One way to think about is like Notion. Imagine if every notion page was a webapp instead of a markdown and then you had an LLM that had access to it all. So anyone who uses productivity software can potentially use it to make their very personal workspace.
I think the main thing is UI and being on the cloud. I used to have all my todos and notes on claude code. But it's much nicer to have a UI that can directly interact with them (e.g. mark something as done or click to view more details). With CC you'd need to spin up a server and frontend and host them etc. Here we abstract those steps away without really reducing capability. You can create a frontend and it can talk to the file system or external APIs very easily.
Yup, basically like Claude code operating on a folder but the folder is on the cloud and it can generate interactive UIs for interacting with the folder.
If you combine an LLM that can run code, a cloud file system, and UI generation, you can create a new kind of os that evolves dynamically with the user.
