Flint

Flint is an AI learning platform that lets teachers turn their own materials into AI-guided student activities and then grade and monitor the results in one place. It describes itself as an agentic LMS: the same system builds activities, tutors students through them and records grades. Its tutor, Sparky, is set up to prompt thinking with questions and hints instead of giving answers.

What is Flint used for?

Schools use Flint to give students one-to-one AI practice tied to what the teacher is actually teaching, with oversight built in.

• Building an activity from uploaded PDFs, slides, documents or links, or through a chat with Sparky
• Running guided tutoring, writing practice, language practice or exam revision sessions
• Giving students speech input and output, a whiteboard, calculator, code runner and cited web search
• Watching student sessions live and getting alerts when someone is stuck
• Grading with rubrics, overriding scores, and reviewing performance insights in a gradebook
• Exporting results to CSV, Word or Google Docs

Who Flint is best for

Flint suits K-12 schools and universities that want students using AI inside teacher-built activities, especially in subjects such as maths, science, computing, English and modern languages. It is used in both US and UK schools, including faith schools and trusts. A single teacher can start on the free tier, which makes it easy to pilot. Teachers who want AI only for their own lesson prep or paperwork will be better served by a teacher-only toolkit.

Flint pricing

As of October 2026, Flint is free for up to 80 users, counting teachers and students together. Paid tiers are billed annually: Tier 1 costs $3,000 per year for up to 150 users, Tier 2 costs $4,000 per year for up to 250 users and Tier 3 costs $6,500 per year for up to 500 users. Paid tiers add SIS and LMS integration, school-wide analytics and a dedicated customer success manager. Schools above 500 users get custom Enterprise pricing with lower per-seat rates. The FAQ says paid plans can also be bought month to month, and prices are listed in GBP for UK schools.

Limitations to keep in mind

• The 80-user free cap is reached quickly once a full class joins
• Paid plans are priced per school, which suits administrators more than individual teachers
• AI feedback and grades still need teacher review
• Students need devices and accounts, which adds setup compared with teacher-only tools

Flint vs alternatives

ChatGPT, Claude and Google Gemini offer powerful general tutoring, but teachers cannot easily watch every student session, set activity rules, or collect grades in one gradebook. Learn About is better for a single learner exploring a topic on their own. Flint wins for schools that want AI tutoring grounded in their own materials, with Socratic guardrails, live monitoring and grading in the same product.

Tips for getting started with Flint

Start with a material you already use, such as a worksheet PDF, and ask Sparky to turn it into a guided practice activity. Test the activity yourself as a student and try asking for the answer outright to see how it responds. Set time limits and deadlines before assigning it. If you plan to roll out beyond one class, count users early, since the free tier includes students.
