I used OneNote extensively for university and found the infinite canvas quite useful, but I ran into limitations, mainly around structure, technical workflows, and embedding capabilities. I ended up building something that fits my needs more closely: Notanic, an infinite-canvas note-taking application with a focus on technical use cases.

Features:

- real-time multiuser editing - native Markdown blocks (including code blocks) - precise sketching and graphing tools with measurements - unlimited hierarchical page nesting - embeds for Desmos, CodePen, GitHub gist, etc. - local-only usage or optional cloud sync

It’s aimed at technical notes, architecture diagrams, math work, visual problem-solving, and mind-mapping.

Available for free on desktop (Windows/macOS/Linux, unlike Onenote :( ) and also as a web app with cloud sync.
