Breef

Breef is a note-taking and study app for students, researchers, and curious learners. It lets users write formatted notes, connect ideas with links, group notes by project or subject, and view them together as a knowledge graph. Web links become previewable badges, and users can import Markdown, images, files, or PDFs. Breef also supports lecture recording and turns audio or PDF material into linked study notes. Spaced reviews, personal flashcards, exam preparation, search, and questions answered from a user’s notes help with learning and recall. The free plan includes core notes and review features, with monthly limits on voice notes, quizzes, questions, file storage, and PDF processing; Pro expands those limits and access to AI features.

Breef is a note-taking and study app for connecting what users learn from courses, books, and the web. It keeps notes, links, and projects together, linking ideas into a knowledge graph that users can explore and review. The app also supports study workflows such as spaced reviews, exam preparation, asking questions of personal notes, and identifying topics not yet covered. Its purpose is to help users build a connected map of what they know rather than leave learning scattered across separate tools. Users write plain text notes, with headings, lists, and tasks formatted as they type, and link related notes using [[. They can group notes by project and subject, paste web links for badges and previews, and add images or files. Breef can turn voice recordings and PDF slides into study notes, with transcripts or source material retained. Notes appear in a knowledge graph; users can search them, review them on a spaced schedule, prepare for an exam date, or ask questions answered from their notes. Breef describes itself as built for students, researchers, and curious lifelong learners. Students can connect ideas across a course, researchers can keep years of reading tied to the ideas it shaped, and curious learners can follow questions across subjects. Its notable distinction is that it brings notes, links, projects, review, and exam preparation together, showing connections on a knowledge map and how that map develops over time.
