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.

Read Japanese text — even inside images — with AI that defines words in context.
Scan Japanese text from manga pages, photos, screenshots and scanned books — material that plain popup dictionaries and browser extensions cannot process.
Select a passage and Yomitai explains each word as it is used in that sentence, rather than presenting a long list of dictionary senses.
Have any passage read aloud by an AI voice when the text is still too hard to parse yourself.
Collect the vocabulary you meet, keep it as an annotated board, and export pinned words straight into Anki flashcards.
