Flashlab.io

Turning a PDF or a YouTube video into flashcards and practice quizzes is the main job of Flashlab.io, an AI flashcard maker geared toward students preparing for exams.

You feed in your study material, and the AI drafts cards and quiz questions from it, which saves the hours you would spend writing them by hand.

Studying then follows spaced repetition and active recall, two methods built around reviewing material right when you are likely to forget it.

Flashlab.io adds a gamified layer on top and tracks your progress and performance, so you can see which topics are still weak.

Its category tags also cover a homework helper, a PDF summarizer and a YouTube summarizer.

Full access may require a subscription, and customization is limited in places.

Because the AI writes the content, you should skim the generated cards for mistakes before relying on them for a test.
