Flint is an AI-powered personalized learning platform built specifically for K-12 schools, helping teachers and students make learning more engaging, interactive, and tailored to every learner. Instead of offering a one-size-fits-all experience, Flint uses its AI assistant Sparky to create personalized lessons, quizzes, writing activities, coding exercises, and instant feedback based on each student's learning pace, interests, and goals. Teachers can upload their own PDFs, presentations, websites, and other learning materials to build AI-powered classroom activities, while schools benefit from analytics, AI guardrails, LMS integrations, and full administrative visibility. Today, Flint supports over 400,000 teachers and students worldwide, and users especially appreciate its easy setup, classroom-safe AI, personalized tutoring, multilingual support, and the time it saves teachers on lesson planning and grading. Flint offers a free plan to get started, while premium plans for schools and districts are available through custom pricing and demos.
