1. Open source. 2. Pure markdown with extended syntaxes, supporting all kinds of diagrams (Mermaid, PlantUML, Vega, ECharts, etc) and LaTeX Math. You can also create slides (powered by Reveal.js) directly in Crossnote. 3. Local widgets support. Such as abc music notation, OCR, Kanban (<- syntax might change in the future), etc. More widgets are coming out in the future. 4. Cloud widgets support. Cloud widgets are those communicate data with our cloud server. The first cloud widget I supported in Crossnote was the `/crossnote.comment` widget, which allows you to make comment directly inside your markdown note. 5. You own your data. All your notes are stored locally (If you are using Crossnote PWA then all notes are stored in your browser). So it's easier to take control of your data. 6. Coming out soon: P2P based real-time collaborative editing 7. And many more ;)

That's all I can think about right now :) Thank you
