AppFlowy-IO/AppFlowy ? reverse-engineered prompt

Build me a collaborative workspace app, basically an open-source alternative to Notion. It should be a single place for managing projects, creating wikis, and general team collaboration. I want it to have flexible views for data, like kanban boards for tracking tasks and powerful tables or grids for organizing information. The editor is important—it needs to support creating rich documents like a wiki.

The most important part is that it must be private and give users full control over their data, unlike the big proprietary apps. It should also have some AI features integrated to help with writing and organization. Make sure it's a cross-platform desktop app that works on Mac, Windows, and Linux, and ideally has mobile apps too. The overall vibe is modern, clean, and extensible, allowing users to build their own systems.
