The honest take

Knowt is genuinely good if you like creating flashcards manually. The Quizlet import is handy, and the free tier is generous.

But if you have existing materials—PDFs from class, lecture recordings, photos of your notes—Knowt can't help you convert those. You'd have to type everything manually.

That's where Laxu AI shines. Upload your materials, and we do the extraction work. Less typing, more studying. If you already have your content in digital form, Laxu AI will save you hours.

Common questions

Is Laxu AI better than Knowt?

It depends on how you study. Laxu AI is better if you have PDFs, lecture recordings, or images you want to convert to flashcards automatically. Knowt is better if you prefer typing your own flashcards manually or want to import Quizlet sets. Both are free to start.

Is Knowt really free?

Yes, Knowt has a generous free tier with unlimited flashcard creation. The free version includes ads. Knowt Plus ($5.99/month) removes ads and adds some features. Laxu AI's free tier gives you 2 full uploads with all features, then $4.99/month for unlimited.

Can Laxu AI replace Knowt?

For most students, yes. Laxu AI does everything Knowt does (flashcards, quizzes, spaced repetition) plus adds PDF upload, audio transcription, and image-to-flashcard conversion. The main thing Knowt has that Laxu doesn't is direct Quizlet import.

Which app is better for ADHD students?

Both work well, but Laxu AI may be better because it reduces the manual work of creating flashcards. Upload your materials and let AI do the extraction—less friction means you're more likely to actually study.

Does Knowt work with PDFs?

Knowt doesn't have direct PDF-to-flashcard conversion. You'd need to manually copy text from your PDF and paste it into Knowt. Laxu AI lets you upload PDFs directly and automatically extracts flashcards.

Which is better for language learning?

Knowt has more pre-made vocabulary sets. However, Laxu AI has full Spanish language support and can generate flashcards from any language materials you upload. For Spanish speakers, Laxu AI is the better choice.

Can I turn my lecture recordings into flashcards?

Yes, with Laxu AI. Record your professor's lecture (or upload an existing audio file), and Laxu AI will transcribe the audio and generate flashcards from the content. Knowt doesn't support audio-to-flashcard conversion—you'd need to manually transcribe and type the content yourself.

How does Laxu AI handle handwritten notes?

Take a photo of your handwritten notes with your phone, upload it to Laxu AI, and the AI will read your handwriting (even messy notes) and convert it into digital flashcards. Knowt requires you to type everything manually.

Can I export Laxu AI flashcards to Anki?

Yes, Laxu AI Pro users can export their flashcard decks to Anki format (.apkg files). This is useful if you want to use Laxu AI for quick flashcard generation but prefer Anki's review interface. Knowt doesn't support Anki export.

Which app is better for medical students?

Laxu AI is typically better for medical students because you can upload textbook PDFs, lecture slides, and anatomy images directly. The AI extracts flashcards from dense medical content automatically. Knowt would require typing all that content manually.

Got materials to convert?

Upload one PDF. Get flashcards, notes, and a quiz—automatically. No typing required.
