TL;DR
Last updated: April 2025
An audio to flashcard generator transcribes spoken audio content and automatically converts it into question-and-answer revision cards. Instead of manually re-listening to lecture recordings or educational podcasts to take notes, you upload the audio file and receive a ready-to-study flashcard set in under a minute.
Shinyu.ai uses Gemini AI to transcribe audio in 50+ languages and extract the key educational content into flashcards with difficulty ratings. It works for lecture recordings, educational podcasts, voice notes, and any audio with clear spoken content. If you prefer quiz questions instead, use Audio to Quiz to generate MCQs from the same recording.
The flashcard generator works best with audio that has clear speech and structured educational content — lectures, tutorials, podcasts, and voice notes all produce strong results.
Re-listening to a recorded lecture is one of the most time-consuming and least effective revision methods — a 60-minute lecture still takes 60 minutes the second time. Research by Roediger & Karpicke (2006) found that students who practised active recall via flashcards retained 50% more information after one week than students who reviewed the same content passively.
Have your study material in a different format? Shinyu.ai generates flashcards from every source — no copy-pasting required. Use PDF to Flashcards to upload a PDF textbook directly, YouTube to Flashcards for lecture videos, or Text to Flashcards if you have a transcript you prefer to paste. For quiz practice instead, use Audio to Quiz or Audio to Exam from the same recording.
Upload your audio file and the AI transcribes the full spoken content, identifies key concepts, definitions, and facts, then generates question-and-answer revision flashcards with difficulty ratings. Transcription and card generation takes 20–60 seconds.
MP3, WAV, M4A, OGG, FLAC, AAC, and WEBM are all supported — up to 50MB per file. M4A is the default iPhone voice memo format; MP3 is the most common for podcast downloads. Most recordings work without any conversion.

Transcription and flashcard generation typically takes 20–60 seconds depending on recording length. A 30-minute lecture usually processes in under 60 seconds. Longer recordings may take slightly more time.
Yes — download the episode as an MP3 and upload it directly. The AI extracts key concepts from the spoken content and converts them into revision flashcards. Best results come from episodes with clear speech and structured educational content.
Gemini AI supports transcription in 50+ languages including English, Hindi, Spanish, French, German, Mandarin, and many more. Flashcards are generated in the same language as the spoken content in your recording.
The AI generates 8 to 15 flashcards per set depending on the length and content density of the recording. A 30-minute lecture with distinct topics typically produces 12–15 cards. Each card includes a difficulty rating so you can prioritise harder concepts.
Yes — use Audio to Quiz for multiple-choice questions, or Audio to Exam for a full structured practice exam. All three tools work from the same audio upload with no copy-pasting required.
