Diffit
Differentiates a text to multiple reading levels
We publish a full Four-Mismatches fit assessment for the student-facing exam tools first. For this one, the facts below are what we have verified — run the Four Mismatches Test on it yourself for your own students.
Independence: Addestra builds learning products too (MathsTutor, TinkerWell). We never review or score our own, and no tool pays to be listed or to rank higher — how we assess fit.
What it does
What the AI actually does — An LLM text-leveller: adapts any text's reading level, translates, and generates aligned activities while preserving meaning.
Why it was built — Get teachers just-right instructional materials so all students can access grade-level content.
