Recorded lectures are useful. Spending an hour re-listening to find one concept is not.
Audio recordings — lecture captures, podcast episodes, voice notes — are dense with information but designed for sequential listening. Finding a specific point means scrubbing through the whole file. Taking notes from audio is slow and easy to miss context. Most students let recordings pile up unreviewed.
Learnlo transcribes your audio and converts it into a full study pack in under 90 seconds. You get a searchable summary, structured notes, flashcards, a quiz, and a practice exam — all from the audio content. Review a 60-minute lecture recording in 10 minutes of active study.

Frequently Asked Questions
Is the audio summarizer really free?
Yes. Guest users get one complete free study pack from an audio file — including summary, flashcards, quiz, and practice exam — without creating an account. Free accounts get 3 packs per month within a 30-minute monthly audio transcription limit.
What audio formats does it accept?
MP3, M4A, WAV, and most common audio formats. The free plan supports up to 30 minutes of audio transcription per month. Plus extends this significantly.
Does the audio quality affect the results?
Clear recordings produce the best study packs. Lecture recordings with a good microphone, podcasts, and screen-captured audio all work well. Heavy background noise or very low-quality recordings may affect transcription accuracy.
Can I upload a recorded lecture from my university?
Yes. Any audio recording of a lecture, tutorial, or educational content works. Upload an MP3 or M4A of your recorded lecture and Learnlo will generate the study pack from the spoken content.
How is this different from uploading a YouTube lecture?
For YouTube lectures, you paste the URL and Learnlo fetches the content. For audio files (MP3, WAV, etc.) downloaded from your LMS, recorded on your device, or captured from a live lecture, you upload the file directly.
Do I get flashcards and a practice exam too?
Yes. Every free pack includes a summary, key ideas, study notes, flashcards, a multiple-choice quiz, a full AI-graded written-answer practice exam, and a mind map — all from your audio recording.
When should I upgrade?
When you need more than 30 minutes of monthly audio transcription, more than 3 packs per month, or packs that last longer than 7 days. Plus is $9/month.
