Description
Diffit is a free-to-start AI tool that takes any text, topic, or YouTube video and instantly generates versions at multiple reading levels, plus matching comprehension questions and vocabulary support — solving the actual time cost of differentiating one lesson for a mixed-ability classroom.
Key Features
- Multi-level text adaptation: Input any text, topic, or YouTube video and generate versions across roughly 2nd to 11th+ grade reading levels.
- Comprehension questions and vocabulary: Automatically generates matching questions and vocabulary support for each passage.
- 60+ language translation: Outputs can be translated to support multilingual learners.
- Printable graphic organizers: Generates supporting materials beyond the reading passage itself.
- Standards alignment: Content can be aligned to Common Core and other curriculum standards (premium).
- Google Classroom/Docs export: One-click export into existing classroom workflows (premium).
How It Works
A teacher pastes in a piece of text, a topic, a standard, or a YouTube video link, and Diffit generates a set of differentiated materials from that single source — leveled reading passages, comprehension questions, and vocabulary lists — so every student in a mixed-ability class gets content matched to where they are, without the teacher writing three separate versions by hand.
Technical Architecture & Overview
- Core Engine: AI text generation calibrated to specific reading-level bands, paired with automated comprehension-question and vocabulary generation.
- Deployment: Web app at web.diffit.me.
- API Surface: None public — end-user classroom tool.
- Known Limits: Standards alignment and direct Google Classroom/Docs export are reserved for the paid tier; teachers should verify the accuracy of simplified content before use.
Pros & Cons
| Pros | Cons |
|---|---|
| The free plan is permanent, with no credit card or trial period required. | A single-purpose tool, so it doesn’t cover lesson planning or grading like broader platforms. |
| Purpose-built for one problem — differentiation — rather than a broad, unfocused toolkit. | The individual premium tier is priced high for a single-focus tool relative to broader platforms. |
| Supports 60+ languages, directly useful for multilingual classrooms. | AI-simplified content still needs a teacher’s accuracy check before use. |
| First-year teachers can apply for free premium access. | Standards alignment and one-click Classroom export require the paid tier. |
