How it works
01 / RECORD OR IMPORT
Drop into any lecture and hit record. Retenir transcribes in real-time — or import PDFs, slides, and papers.
02 / AI DOES THE WORK
Your content is chunked, embedded, and turned into smart notes, flashcards, and a searchable knowledge graph.
03 / STUDY WITH CONFIDENCE
Auto-generated quizzes surface weak spots. The knowledge graph shows how ideas connect across your whole course.
Features
Real-time transcription with speaker context. Every word timestamped and searchable.
Context-aware summaries with key concepts highlighted. Not an outline — a study guide.
Visualise how ideas connect across weeks. See the thread from Week 1 to your exam topic.
Flashcards and practice questions from your own notes. Spaced repetition built in.
Exam-aware scheduling. Weighted by how much you've struggled with each topic.
Ask anything about your workspace. Gets answers from your notes, not the internet.
