What Is Diffit?
Diffit is an AI tool that helps teachers adapt reading material for students at different levels. A teacher pastes in any text, a web page URL, or a YouTube video, and Diffit generates reading passages rewritten to multiple reading levels, along with a vocabulary list and auto-generated questions and worksheets. The company was founded in 2022. Its focus is narrow and clear: making differentiation — adapting the same material for a class of mixed abilities — fast and practical.
Re-leveling text by hand is one of the most time-consuming tasks a teacher faces. A single article might need to be simplified for a struggling reader and kept rich for an advanced one. Diffit automates that re-leveling and packages the result into ready-to-use classroom resources.
💡Key Concept
Leveled Reading: Presenting the same core content at several reading difficulties so that students of different abilities can all access it. A leveled set of passages lets a whole class study the same topic while each student reads a version pitched to their level. This is a cornerstone of differentiated instruction, and re-leveling text by hand is slow — which is why AI re-leveling is so useful to teachers.
What Diffit Does
- Multi-level passages — rewrites a source text into several reading levels from one input
- Works from many sources — accepts pasted text, a web URL, or a YouTube video as the starting point
- Vocabulary lists — pulls key terms and definitions from the material
- Auto-generated questions — creates comprehension and discussion questions tied to the passage
- Ready-made worksheets — assembles the passage, vocabulary, and questions into usable classroom handouts
How AI Is Applied
Diffit uses large language models to do two things. First, it reads a source — an article, a web page, or the transcript of a video — and rewrites it to a target reading level while preserving the meaning. Producing the same content at, say, an elementary and a high-school reading level is a task language models handle well, because re-leveling is fundamentally a controlled-rewriting problem.
Second, the AI generates the supporting materials: it extracts vocabulary, writes comprehension questions, and organizes everything into a worksheet. This turns a single source into a complete, differentiated lesson packet in seconds.
As with any AI-generated text, the re-leveled passages and questions are drafts. Teachers should skim them to confirm the simplification did not distort facts and that the questions fit their goals before handing them to students.
Who Uses Diffit
Diffit is used by K-12 classroom teachers, especially those teaching mixed-ability groups, English learners, or special-education students who benefit from leveled materials. It is also useful to reading specialists and anyone who regularly adapts complex text for a broad audience of readers.
Pricing
Diffit uses a freemium model. A free tier covers core re-leveling and worksheet generation, and paid plans add more features and higher usage limits. School and district licensing is available on a quote basis depending on the number of teachers. Teachers can start free and upgrade as their needs grow.

Strengths
- Solves a real pain point — automates the slow, manual work of re-leveling reading material
- Flexible inputs — turns text, a web page, or a video into a lesson
- Complete packets — produces vocabulary, questions, and worksheets, not just a passage
- Supports diverse learners — well suited to English learners and mixed-ability classes
- Free to start — the free tier lets teachers adopt it with no purchase
Limitations and Considerations
- Re-leveling needs a check — simplified passages can occasionally lose nuance or introduce errors, so teacher review matters
- Focused scope — it is a differentiation tool, not a full lesson-planning or classroom platform
- Question quality varies — auto-generated questions may need editing to match a teacher's objectives
- Source-dependent — output quality depends on the clarity of the source text or video
Key Takeaways
- Diffit takes any text, URL, or YouTube video and generates reading passages at multiple levels, plus vocabulary, questions, and worksheets
- Its AI automates the time-consuming task of re-leveling reading material for mixed-ability classrooms
- Re-leveled passages and generated questions are drafts that teachers should review for accuracy and fit
- Best for K-12 teachers who need fast differentiation of reading material, including for English learners and special-education students
