Flashcards and study sets with the Q-Chat AI tutor.

A study platform best known for flashcards and learning games, now layered with AI through Q-Chat, a conversational tutor that uses the Socratic method to help students reason toward answers. Quizlet Plus removes daily learning-round caps and unlocks AI tutoring plus Expert Solutions for explaining tough problems. The free tier remains usable with reduced limits.

Khan Academy's AI tutor and teaching assistant.

An AI-powered tutor and teaching assistant from Khan Academy that guides learners through math, science, coding, and the humanities. Rather than handing over answers, it uses Socratic prompts to push students toward their own reasoning. For teachers it drafts lesson plans, rubrics, and exit tickets aligned to Khan Academy's content library.

Turn your course materials into AI flashcards, quizzes, and a tutor.

A study platform that ingests a student's own materials — PDFs, slides, notes, audio, and video — and turns them into flashcards, quizzes, and summaries. Its Spark.E tutor is trained on those uploads to answer questions, generate practice tests, and explain concepts over chat or voice. A free tier offers limited chats and uploads, with paid tiers unlocking unlimited use and a live lecture assistant.
