Diffit: Grade-Level Content at Every Reading Level

Diffit does one job unusually well: give it any topic, pasted text, PDF, article link, or YouTube video, and it returns a reading passage rewritten for the grade level you choose, complete with an adapted vocabulary list and comprehension questions. A single primary source can become a 2nd-grade version, a 7th-grade version, and an 11th-grade version of the same content in minutes — so every student works with the same ideas at a level they can access.

The free tier covers the core loop: generate leveled passages with questions and vocabulary and download them as PDFs. A premium subscription ($14.99/month or $149.99/year) unlocks exports to Google Docs, Slides, Forms, and Classroom plus Microsoft 365, alignment to standards and depth-of-knowledge levels, conversion into graphic organizers and student activities, and support for longer inputs including full novels. Diffit for Schools is a flat-rate annual license tiered by student enrollment that covers all staff.

Ideal Use Case

Diffit is built for classrooms with a wide reading-ability spread — inclusion classrooms, English-learner cohorts, and mixed-level social studies and science courses where the textbook fits almost nobody. Teachers who currently spend evenings hand-rewriting articles for three reading groups get the same differentiation in one generation step, then fine-tune wording and questions before export.

How Diffit differentiates

Where broader platforms offer dozens of generators, Diffit focuses entirely on differentiated reading, and that focus shows in adoption: it is used in thousands of schools and districts (named customers include Hart, Arlington, Kenosha, Rockford, and Forsyth), is backed by NewSchools Venture Fund, and participates in the EdSafe AI Alliance. In a November 2024 survey of 2,517 teachers, 96% said Diffit saves them time and 93% said it helps them reach students where they are.
