Original Summary

Hey r/SideProject ! I'm a solo dev at Endless AI. A while back I watched a math teacher friend struggle through an online lesson — switching between a clunky drawing tool, a PDF reader, and screenshots just to work through one worksheet. So I built Whiteboard: a lightweight whiteboard app designed for teaching. What it does: - Draw math shapes (circles, axes, 3D-ish boxes) with a single stroke — no menu diving mid-lesson - Import and annotate multi-page PDFs / worksheets directly on the canvas - Infinite canvas + paged mode, grids and paper backgrounds - Laser pointer, colored pens, focus mode for projecting to a class - Export/share lessons It's native on iPad (Apple Pencil), iPhone, Mac, Android, Windows, and Linux — under 100MB, no account needed, files stay on your device. Free to download; a few Pro features vary by platform. Honest ask: I'm a developer, not a teacher — I'd love feedback from anyone who's taught with a tablet. What would actually make you switch whiteboard apps? What's missing? https://endlessai.org/   submitted by   /u/readhub [link]   [comments]
