Make powerful, intelligent flashcards from your own notes in seconds
Snap a photo of your notes, textbook, or worksheet. Lexie reads your content and generates flashcards that help you spend more time on challenging material, and less on what you already know.

How it works

Photograph your study material
Take a photo of your textbook, lecture notes, handwritten notes, or worksheet. Lexie extracts the content and identifies the subject and language automatically.

Lexie generates flashcards from your content
Lexie analyses your material and creates structured question-and-answer flashcards focused on the key concepts. Not copied text on cards — real questions that test understanding. Review and edit before you start.

Review with spaced repetition
Lexie uses the FSRS algorithm to schedule your reviews at optimal intervals. You see cards again right before you'd forget them. The result is long-term retention, not short-term cramming.
Not your typical flashcard app
Active recall, not passive recognition
Lexie generates fill-in-the-blank and recall questions, not just front-and-back cards. Recognising an answer when you see it is not the same as producing it from memory. Lexie tests the version that matters.
Spaced repetition built in
The FSRS algorithm tracks what you know and what you don't. It schedules reviews at scientifically optimal intervals so you spend your time on the material you're weakest on, not the material you've already mastered.
Any subject, any language
Biology, French, history, chemistry, law, medicine. Lexie works with any content in 34+ languages. Your notes become your study material, regardless of what you're studying or where.
