How to switch from Knowt to Laxu AI
If you're tired of typing every flashcard manually, here's how to start generating them automatically with Laxu AI:
Upload your study materials
Upload your lecture PDFs, photos of notes, or audio recordings to Laxu AI. The AI extracts key concepts and creates flashcards in under 2 minutes—no manual typing required.
Review and edit
Check the generated cards, edit any that need adjustment, and add manual cards for specific concepts. This takes a few minutes compared to hours of typing.
Study or export
Use Laxu AI's built-in flashcard review, practice quizzes, and spaced repetition. Or export your deck to Anki format if you prefer Anki's review interface.
When to use Laxu AI vs when to use Knowt
Each app has strengths for different situations. Here's a guide:
Use Laxu AI when...
- • You have PDFs, slides, or notes to convert automatically
- • You want flashcards from lecture recordings
- • You want notes + quizzes alongside flashcards
- • You need to convert handwritten notes to digital cards
- • You want to export to Anki format
Use Knowt when...
- • You prefer creating flashcards from your own typed notes
- • You need to import existing Quizlet sets
- • You want built-in AP exam prep content
- • You need an Android app right now
- • You want the most generous free tier possible
The honest take
Knowt is genuinely good. It rose to popularity when Quizlet paywalled its Learn mode, and for good reason—the free tier is generous, the Quizlet import is seamless, and the AP exam prep content is a real differentiator. If you prefer typing your own flashcards from notes, Knowt is a solid choice.
The limitation is input methods. Knowt's AI only works from notes you type or paste. If you have a 50-page PDF, a lecture recording, or a photo of your handwritten notes, you'd have to manually transcribe everything before Knowt can help.
That's where Laxu AI is different. Upload your PDF, drop in an audio file, or snap a photo—and get flashcards, notes, and quizzes without typing a single word. If your study materials exist as files, Laxu AI will save you hours of manual work.
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 creating flashcards from typed notes, want to import your Quizlet sets, or need AP exam prep content. Both are free to start.
Is Knowt really free?
Yes, Knowt has a genuinely generous free tier with unlimited flashcard creation and study modes. The free version includes ads. Knowt Plus costs around $9.99/month or $59.88/year and removes ads with added features. Laxu AI's free tier gives you 1 upload with all AI features plus unlimited manual creation, then $4.99/month for unlimited uploads.
Can Laxu AI replace Knowt?
For most students, yes—especially if you have existing study materials to convert. Laxu AI does flashcards, quizzes, and spaced repetition plus adds PDF upload, audio transcription, and image-to-flashcard conversion. The main things Knowt has that Laxu doesn't are direct Quizlet import and built-in AP exam content.
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's note editor, then generate cards from that. Laxu AI lets you upload PDFs directly and automatically extracts flashcards, notes, and quizzes.
Which app is better for AP exam prep?
Knowt has a clear edge here with built-in AP exam prep content, practice tests, and study guides for many AP subjects. Laxu AI doesn't have pre-made AP content, but you can upload your AP textbook PDFs and class notes to generate custom flashcards from your specific materials.
Can I import my Quizlet sets into Laxu AI?
Not directly. Knowt is the better choice if Quizlet import is essential—it supports seamless Quizlet set import. Laxu AI takes a different approach: instead of importing old flashcards, you upload your source materials and let AI generate fresh, comprehensive cards.
Which 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. Knowt's clean interface is also ADHD-friendly for manual card creation.
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.
Which app has a better mobile experience?
Knowt has both iOS and Android apps, giving it broader mobile coverage. Laxu AI currently has an iOS app with Android coming soon. Both offer clean mobile interfaces. If you're on Android, Knowt is currently your only option between the two.
What is the best flashcard app for college students?
It depends on your workflow. If you get lecture slides and PDFs from professors, Laxu AI saves hours by converting them to flashcards automatically. If you prefer building flashcards from your own notes or want to import Quizlet sets, Knowt's generous free tier is hard to beat.
Got materials to convert?
Upload one PDF. Get flashcards, notes, and a quiz—automatically. No typing required.
