Common questions
How do I record a lecture with Laxu AI?
Open the app on your phone or computer and tap record. When the lecture ends, Laxu AI automatically transcribes and generates flashcards, notes, and quizzes from the content.
Does it work offline?
Recording works offline. Transcription and flashcard generation happen when you're back online.
How long can I record?
There is no time limit on recordings. You can record a full 3-hour lecture on both free and Pro accounts. The recording continues as long as you need it.
Is the transcription accurate?
Laxu AI uses Whisper, one of the most accurate speech-to-text models available. In a quiet classroom, accuracy is typically above 95%. Background noise, heavy accents, or low-quality microphones can reduce accuracy, but you can always edit the generated flashcards and notes after processing.
Can I also upload existing recordings?
Yes! If you already have lecture recordings, upload them directly. Check out our Audio to Flashcards feature.
