Diffit

Diffit is an AI tool that solves one of teaching's hardest daily challenges: differentiation. It takes any text — an article, a topic, a YouTube video, or your own content — and instantly adapts it to different reading levels, so every student in a mixed-ability classroom can access the same material at a level they can actually read. A single class might have students reading three grade levels apart; Diffit lets a teacher hand each the same lesson, appropriately leveled, in seconds.

Beyond leveling text, Diffit generates a complete resource package around any topic: a leveled reading passage, vocabulary lists, summaries, and question sets (multiple choice, short answer, open-ended) — a full differentiated lesson from a single input. It supports multiple languages too, helping English-language learners access grade-level content.

Diffit offers a free plan covering core features, with premium and school plans adding more generations, export options and advanced features.

Strengths: it genuinely solves differentiation (a real, hard, time-consuming problem) in seconds, generates complete resource sets not just leveled text, supports multilingual access, and has a useful free tier. Weaknesses: AI-adapted text needs teacher review for accuracy and appropriateness, some export/advanced features are paid, and it's focused on text-based subjects.

For teachers with mixed-ability classrooms, English-language learners, or anyone who's spent evenings manually rewriting texts for different levels, Diffit is one of the most practically valuable AI tools in education — turning hours of differentiation work into a one-minute task while keeping every student on the same lesson.
