Free AI flashcard and study tools for students
Upload up to 30 files and Kai instantly produces notes, flashcards, summaries, and practice resources from them.
Convert Quizlet, Kahoot, Wayground, and YouTube content, or record live lectures to generate notes and study sets.
Upload class files to get a study plan and exam prediction that highlights what your professor emphasizes most.
Kai quizzes you by voice and can turn any note or flashcard into a podcast for study on the go.

Turn lectures, meetings, PDFs and videos into structured notes, flashcards and quizzes
Type, record voice, upload audio files (MP3, WAV, M4A, AAC, OGG), import PDFs and Word documents, add web and video links, or scan images and screenshots with multi-language OCR.
Every note can generate a summary, flashcards, a quiz, a mind map, an infographic, a podcast and an AI chat you can question — all tied to the same source material.
Recordings become a full transcript plus a summary, with next steps converted into a to-do list in the editor and minutes shareable via a single link.
Ask questions and get answers drawn from your own document rather than generic model knowledge, which makes revision and fact-checking far more reliable.
