Microsoft OneNote

Microsoft OneNote organizes typed notes, handwriting, drawings, images, files, audio, and shared class or project material in freeform digital notebooks. It syncs across web, Windows, Mac, iOS, and Android and supports real-time collaboration, digital ink, searchable content, and voice transcription. Copilot in OneNote can draft plans, generate ideas and lists, summarize information, and reorganize notes from natural-language prompts. Core OneNote use is free, while integrated Copilot features depend on eligible Microsoft 365 plans.
