Diffit, founded in 2023, solves a specific, well-defined teaching problem: differentiated instruction, taking a single text or topic and automatically generating multiple versions written at different reading levels, so every student in a mixed-ability classroom can engage with the same underlying content at a level they can actually access.
That narrow focus on differentiation specifically, rather than broader lesson planning or quiz generation, means a teacher can take an article, a topic, or existing classroom material and get several leveled versions back in one pass, along with accompanying vocabulary support and comprehension questions matched to each level.
A free tier covers limited use, and paid plans start around $14 a month for more generation volume. For a teacher managing a classroom with a wide range of reading abilities specifically, Diffit's narrow, well-executed focus on differentiation solves that specific, common challenge more directly than a broader lesson-planning tool treating differentiation as a secondary feature.
