Show HN: Napkinbook, a smart canvas for discovering, and sharing insights

Napkinbook is a smart canvas for collaboration, sharing, and discovering insights.

I think of it as a more computational version of Excalidraw or Miro: a flexible canvas where you can think, build, present, and collaborate without constantly moving between different tools.

Since my first Show HN, I’ve added:

* Much better mobile support * AI-assisted brainstorming * Presentation decks with animations * Shareable reports * Live collaboration * Actual Git history

The goal is to make the canvas itself the workspace, rather than treating whiteboarding, presenting, reporting, and version history as separate products.

I’d love feedback, especially on the interaction model and where this feels meaningfully different from existing canvas tools.
