You recorded the lecture. The content is in the file. Getting it into flashcards should not take an hour.
Students who record lectures face a two-step problem: first they need to extract what is important from the recording, then they need to convert it into a format that supports active recall. Both steps together typically take as long as the original lecture.
Learnlo compresses both steps into a single upload. Your audio is transcribed, the key concepts are extracted, and active recall flashcards are generated from the specific content in under 90 seconds. You get a ready-to-study flashcard deck from your recording without touching a card template.
Before Learnlo
Spending an hour transcribing notes and building a flashcard deck from a recorded lecture you need to study
After Learnlo
Free active recall flashcards generated from your audio recording in 90 seconds — ready to study immediately

Upload your audio file
MP3, M4A, WAV, or other audio format within the free plan's 30-minute monthly limit. No account needed.
Flashcards are generated from the audio
Learnlo transcribes the recording and creates active recall cards from the key concepts, terms, and relationships covered.
Review your flashcard deck
Flip through cards and test your recall from the lecture. Mark what you know and what still needs work.
Go deeper with the practice exam
Written-answer exam from the same audio lets you test whether you can explain the concepts from memory.
From Audio Flashcards to AI-Graded Exam
Flashcards from your recording build recognition. The practice exam from the same content tests whether you can retrieve and explain the concepts under exam conditions.
Example — AI Exam Grading
Question
Define opportunity cost and explain how it applies to an individual's decision to attend university.
Student Answer
Opportunity cost is what you give up when you make a choice. Going to university means giving up income you could have earned from a job.
AI Grading Feedback
7 / 10Good foundation — you correctly defined opportunity cost as the value of the next-best alternative forgone. Your example is accurate and relevant. To score full marks: be explicit that opportunity cost includes both direct costs (tuition, materials) and indirect costs (foregone wages, work experience), and note that the relevant comparison is the individual's best alternative use of the same time and money — not just any job, but the most valuable one they could realistically obtain. Economists also include the subjective value of the lifestyle and career trajectory foregone.
Frequently Asked Questions
Is this really free?
Yes. Guest users get a complete free flashcard set — plus the full study pack — from any audio file without creating an account. Free accounts get 3 packs per month within a 30-minute monthly audio transcription limit.
What audio formats are supported?
MP3, M4A, WAV, and other common audio formats. Files up to 25 MB on the free plan.
How many flashcards will I get from an audio recording?
Typically 15–30 cards, scaling with the length and concept density of the recording. A 45-minute lecture with many distinct topics will produce a larger deck than a 10-minute focused tutorial.
Do I also get a quiz and practice exam from the same recording?
Yes. Every free pack includes flashcards, a multiple-choice quiz, a full AI-graded written-answer practice exam, structured notes, and a mind map — all from your audio file.
What audio quality is needed?
Clear voice recordings produce the best results. Most lecture recordings with decent microphone quality, course podcasts, and downloaded audio content work well. Heavy background noise may reduce accuracy.
What is the difference between this and the audio-to-flashcards page?
Both access the same Learnlo tool. This page is focused specifically on the free-tier experience for audio uploads — useful for students comparing free options across tools.
When would I upgrade?
When your recordings exceed 30 minutes per month, you need more than 3 packs, or you want packs to persist longer than 7 days. Plus is $9/month.
