Teacher tool that adapts any text or topic to a chosen reading level
Diffit is a tool for teachers that takes a source - an article, a PDF, a video or just a topic - and rewrites it at a chosen reading level, from early years to advanced. Along with the levelled text it produces comprehension questions, vocabulary lists with student-friendly definitions, and short answer or multiple-choice activities, all editable before printing. Teachers use it to differentiate one lesson for a mixed-ability class without rewriting material by hand. Free accounts get a monthly allowance of resources, and the company sells teacher and school plans. Generated material should still be reviewed before it reaches students.

A pasted article, an uploaded document, a video link or simply a topic you type in. The tool then produces a levelled version of the material along with questions and vocabulary for that level.
Always. Adaptations can simplify or subtly shift meaning, and generated questions may have more than one defensible answer. A quick read-through is essential before handing anything to students.
The tool works with teacher-supplied material rather than student accounts, which keeps the data picture simpler than a student-facing app. Schools should still confirm the terms before wide deployment.
