Flint K-12 is an AI-powered educational platform that supports teachers and students in K-12 settings. The platform is a customizable teaching and tutoring assistant that helps educators produce activities, worksheets, quizzes, assignments, etc., from a set of common input. It can customize activities and assessments to meet the specific needs of each student. For students, Flint provides immediate feedback, allows for interactive math problem solving with feedback, allows students to submit essays based on teacher-supplied rubrics for feedback, allows for world-language practice in over 50 languages and dialects, and even provides debugging assistance for computer-programming assignments.

Its AI tutor, named “Sparky,” adapts to each learner's personalized level of development and does not give away answers to problems during a tutoring session but instead gently scaffolds each learner's learning while still maintaining the student's ability to act autonomously. Ultimately, Flint K-12 assigns an importance to responsible AI use. Flint K-12 has its own search of web content, content upload (PDFs, slides, etc.), math verification engines, data privacy, and privacy safeguards, and it does not allow any of its student data to be used for training models.
