Scan a math problem with your camera for step-by-step solutions.

A mobile math app that solves problems scanned with a smartphone camera, using OCR and AI to recognize handwritten and printed equations from arithmetic through calculus. It returns detailed step-by-step explanations to help students learn the method, not just the answer. The free app handles many problems, while Photomath Plus adds animated tutorials and textbook solutions.

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.

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.
