Every teacher knows the challenge: in one classroom, you have students who race ahead, students who need more time, and students who just don’t connect with the material. Personalizing lessons for all of them feels impossible: not because you don’t want to, but because the time and tools have never been there.
Flint was built to change that. It helps teachers design lessons that meet every learner where they are, without starting from scratch each time. The result? Classrooms where more students feel seen, engaged, and excited to learn.
Flint’s AI activity builder makes lesson design fast, flexible, and fun. Just describe what you’re teaching, like “a 9th-grade persuasive writing activity," and Sparky, your AI teaching assistant, instantly generates interactive activities you can customize on the spot. Each activity can be adjusted for reading level, pacing, and format, so you can deliver personalized instruction that meets each student where they're at.
Every class has students who learn differently, and Flint helps you meet them where they are. With a few clicks, you can create multiple versions of the same assignment, scaffold questions, or translate content into 200+ world languages. That means differentiated instruction that’s actually doable without doubling your prep time.
Flint helps you understand how students are thinking. As students respond in activities, Flint’s has live classroom analytics surfacing key insights like engagement, understanding of the material, predictive grades, and even auto-generates follow activities. Make formative assessment and data-driven instruction part of everyday teaching.
