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.

One-click AI summaries of any webpage from your Chrome sidebar
Press the sidebar button on any page and ReadSmart returns a condensed summary of the page's text without you scrolling through everything.
Rather than dumping the whole page into a summary box, the extension detects the main textual content, which works best on news sites and long-form blogs.
Summaries you have already generated are kept, so you can return to a page you read earlier and jump straight back into the gist.
The extension lives in the Chrome sidebar, so generating a summary never pulls you out of your current tab or workflow.
