About Diffit
Diffit takes a topic, article URL, PDF, or YouTube video and instantly generates a reading passage at the exact reading level you specify — from 1st grade through 12th grade — plus comprehension questions, vocabulary lists, and graphic organizers. The core use case is differentiation: instead of finding three separate texts at three reading levels, a teacher inputs one source and Diffit outputs all three variants simultaneously.
The platform is entirely teacher-facing. Students never log in, which eliminates student data collection and simplifies FERPA compliance. Outputs export to Google Docs, Google Slides, Microsoft Word, and PDF. The free tier covers the full differentiation workflow with no generation limits — the paid Individual Teacher plan ($14.99/month or $149.99/year) adds export format flexibility. School plans include an admin dashboard and enrollment-based pricing.
Diffit is FERPA and COPPA compliant, holds SOC 2 certification, and earned a 93% privacy rating from Common Sense Media. Co-founded by Vlad Gutkovich (Flocabulary, Seesaw) and Adam Black (Teach for America, Summit Public Schools), both with deep roots in equity-focused education.
