Diffit is an AI differentiation tool used by 1M+ teachers. It takes any source (a news article, a PDF, a YouTube link, a topic prompt) and generates reading-level-appropriate versions across the grade spectrum, each with comprehension questions, vocabulary activities, and summaries. It’s the most focused tool in the education AI category, and it earns a 9/10 from multiple independent reviews for depth in its lane.
For this review, we assessed source handling, reading-level adjustment, Diffit Chat, scaffolds, citations, exports, privacy, and the differences between Basic and Premium.
The text adaptation engine is the headline feature. Enter a URL, paste an article, or describe a topic, and Diffit produces versions from approximately second grade through high school reading level. Each version maintains the same core content and concepts, adjusts vocabulary complexity and sentence structure, and generates comprehension questions appropriate to that level. What used to take a teacher 2-3 hours on a Sunday (rewriting the same article at three reading levels) takes under 60 seconds.
Multilingual translation carries scaffolds across with the body text, not just the words. When a passage is translated to Spanish, the comprehension questions and vocabulary cards translate too. For ELL teachers managing students who speak different home languages, a single input generates a complete differentiated set.
The 2026 catalogue has expanded significantly beyond its original scope. Station rotations, lesson kits, unit tests, choice boards, graphic organizers, and DOK-level aligned questions are now available alongside the core reading differentiation tools. Standards alignment (CCSS, NGSS, state-specific) tags generated materials to the relevant standards automatically on paid plans.
The free plan covers the core differentiation use case with limited access, PDF export, and 90-day history. Premium exports to Google Classroom, Google Docs, Google Slides, and Google Forms require a paid plan.
Individual Teacher: $14.99/month or $149.99/year. Diffit for Schools is custom annual pricing based on enrollment.
