OneNote

OneNote is a free‑tier note‑taking application that lets users capture and organize information across devices. The web version provides a browser‑based interface where text, images, and other content can be entered, and it supports clipping material from web pages directly into a notebook. Users can create multiple notebooks, sections, and pages to structure their material and can search across all stored content.

Collaboration features allow several people to view and edit the same notebook simultaneously, making it suitable for shared projects or classroom settings. Changes sync automatically, so the latest version is available on any device with internet access.

The service is offered by Microsoft and is positioned as a free tool for personal and collaborative note‑taking, with a stable release status and a focus on accessibility from any platform that can run a web browser.
