Endless AI and Excalidraw offer digital whiteboarding solutions

Digital whiteboarding tools Endless AI and Excalidraw provide diverse options for visual communication, collaboration, and note-taking.

Endless AI has released Whiteboard, a cross-platform tool compatible with iPad, iPhone, Android, Mac, Windows, and Linux. It features both finite paged layouts and infinite canvas modes, supporting handwriting, typed input, and PDF annotation. The tool includes specialized templates for sports and court layouts and offers a freemium model with optional Pro features via subscription or one-time purchase.

Excalidraw is an open-source, free whiteboarding application focused on simple, expressive tooling and ease of collaboration. It utilizes a straightforward security model where users can share unique links for instant editing. The platform is mouse-centric but touch-compatible and includes extensive keyboard shortcuts. Due to its open-source nature, it can be embedded into other applications, such as Obsidian, as editable vector illustrations.
