Its pitch is consolidation: rather than juggling several apps, students upload their class materials once and get flashcards, notes, summaries, and practice tests generated in one place. Importing existing Quizlet sets takes a couple of clicks, including images and formatting. The AI layer is powered by Kai, an assistant that works across PDFs, slides, images, videos, and live lecture recordings. Uploading files produces notes, flashcards, and quizzes automatically, and Kai can also answer questions about your materials and explain why a practice answer was wrong. An Exam Predictor and Planner builds a study schedule from uploaded course files, while Voice Tutoring & Podcasts let students be quizzed aloud or turn notes into audio for studying on the go. Knowt is free to use for core studying, with unlimited learn mode and free practice tests. It is widely adopted in education, with millions of students and teachers using it and a strong presence in AP exam preparation, alongside SAT and ACT resources and a Chrome extension for on-screen study. **Pricing & Plans:** Knowt's core features are free: unlimited learn mode, free practice tests, flashcard creation, imports, and AI study tools with reasonable usage limits.
