An audio to notes generator transcribes spoken audio content and automatically converts it into structured study notes. Instead of manually re-listening to lecture recordings or educational podcasts to take notes, you upload the audio file and receive organised notes with an overview, key points, topic sections, and takeaways — in under a minute.
Shinyu.ai uses Gemini AI to transcribe audio in 50+ languages and extract the key educational content into a proper set of study notes. It works for lecture recordings, educational podcasts, voice notes, and any audio with clear spoken content. If you prefer flashcards instead, use Audio to Flashcards — or generate MCQ quiz questions from the same recording.
Re-listening to a recorded lecture is one of the most time-consuming revision methods — a 60-minute lecture still takes 60 minutes the second time. Converting your lecture recording to structured notes means you capture all the key content from the audio once, in a format you can scan, copy, and use directly for revision — in under a minute.
Use the notes as a reference for understanding, then pair with Audio to Flashcards for active recall practice or Audio to Quiz for MCQ testing. All three tools work from the same audio file — no transcript copying or manual note-taking required.
