toeverything/AFFiNE ? reverse-engineered prompt

I want to build an all-in-one productivity app that's like a combination of Notion and Miro. The main idea is that a user shouldn't have to choose between a text document and a whiteboard. It should be a single, unified canvas where you can write structured notes, but also freely draw, add sticky notes, create diagrams, and embed web pages anywhere you want.

It needs to be 'local-first' so people own their data and can work offline, but it should also support real-time collaboration when you're online. Let's also include database functionality, so you can create tables that can be viewed as a grid or as a Trello-style Kanban board. Finally, build in an AI assistant that can help with writing, summarizing content, or brainstorming ideas directly on the canvas. It should be a web app, but also available as a self-hostable desktop app.
