Flint

Flint sells to schools, not to individual teachers. The pricing page says it is free for up to 80 users, who can be teachers, students or administrators. Above that it lists $3,000 a year for up to 150 users, $4,000 for up to 250 and $6,500 for up to 500, with custom pricing beyond 500. Every paid tier says Contact sales, so there is no self-serve checkout. The page’s $1.67, $1.33 and $1.08 per user per month are the provider’s division of those yearly prices for a full tier.

Two things on the same page need a question to sales. The headline calls the 80-user plan free, but the pilot FAQ calls it a free trial and gives no end date. And the FAQ says schools on the free plan get a faster AI model, while paid and trial schools get a more capable one.

Up to 80 users cost nothing. At 120 users a school is in the $3,000 tier, so each user costs $25 a year; fill the tier to 150 and it drops to $20. At 250 users the $4,000 tier is $16 and at 500 users the $6,500 tier is $13. Because the tiers step at 80, 150, 250 and 500 users, one extra user past a limit moves a school into the next price, so count teachers and administrators as well as students.

According to the features page and FAQ, teachers build activities from their own PDFs, slides or links, watch a live sessions table, read any student’s transcript, set rubrics and create follow-up activities. Administrators can read all messages school-wide, and Flint flags messages about violence, harassment, self-harm or sexual content for review. SIS and LMS rostering runs through Edlink and does not yet support grade passback, and sign-in works with Google or Microsoft accounts.

The security page says Flint does not train models on user data, is GDPR compliant and FERPA-aligned, and has signed state data processing agreements in seven states. It also says no user data is shared with third parties, while the FAQ names Anthropic, OpenAI, Vercel, Supabase, Mixpanel and Sentry as providers, so ask for the subprocessor list. The FAQs page gives support chat hours as 9 AM to 9 PM US Eastern in one answer and 24/7 in another. The 200,000 teacher figure and 98.5% speech accuracy are the provider’s claims with no method shown.

1. Ask sales in writing whether the 80-user plan expires and which AI model the free plan uses.
2. Have the teacher build one activity from a real handout and assign it to the class.
3. Read three student transcripts and check whether the AI gives hints instead of answers.
4. Check that the alerts and administrator views show what your school’s policy requires.
5. Request the subprocessor list and your state’s data processing agreement.

Accept it if the transcripts show hints rather than finished answers and the data terms fit your policy. Reject it if the free plan expires without notice or the data answers conflict. No result is recorded here.
