Flint
AI tutoring platform built for K-12 schools
About
Flint gives schools an AI learning platform centered on Sparky, an AI tutor teachers can shape into custom activities like essay workshops, quizzes, and subject conversations. Teachers build activities from their own materials, and students can also chat with Sparky on their own; the company's own testing suggests it coaches rather than hands over answers. It is free for students, with schools paying and a free plan covering up to 80 users, which makes it accessible but means adoption depends on school budgets.
