Blackboard

Blackboard is an AI-powered infinite canvas that replaces your note app, diagram tool, and tutor in one workspace. Write by hand or type, sketch or generate diagrams with AI, embed Desmos graphs, and highlight any region to ask the AI to explain or quiz you on it — all on a boundless canvas with dark mode, folders, and auto-save. Built for visual thinkers who want one tool that adapts to how they learn and create.
