Diffit

Quick answer

Diffit is the best AI tool for teachers whose main pain point is differentiation. It takes any topic, article, or text and instantly adapts it to multiple reading levels, with built-in vocabulary and comprehension questions. If you teach mixed-level classes and spend hours adapting materials, Diffit is worth shortlisting.

What is Diffit?

Diffit is an AI tool that does one job extremely well: turning one source into multiple reading levels. You paste text, enter a topic, or drop a URL. Diffit generates versions at different Lexile levels, adds vocabulary support, and creates comprehension questions — all aligned to the adapted level.

That focus is why many teachers prefer it over broader platforms. It is not trying to be an all-in-one teacher assistant. It is solving a specific, time-consuming classroom problem.

Why teachers and schools care about it

Differentiation is one of the most labor-intensive parts of teaching. Teachers routinely:

• adapt textbook passages for different readers
• create multiple versions of the same assignment
• scaffold vocabulary and comprehension for mixed-level groups

Diffit compresses that workflow. Instead of manually rewriting or hunting for leveled materials, teachers get usable output in minutes. For schools with limited curriculum budgets or high variability in reading levels, that can matter more than a platform that does many things adequately.

Key features

Instant differentiation

• Paste any text or enter a topic to generate versions at multiple Lexile levels
• Output available in 50+ languages
• Vocabulary lists and student-friendly definitions included

Comprehension support

• Auto-generated multiple choice, short answer, and open-ended questions
• Questions aligned to the adapted reading level
• Key terms highlighted with definitions

Classroom integration

• Google Classroom integration to push assignments directly
• Export options for common formats
• Works with existing curriculum materials

Where Diffit is strongest

Diffit is strongest when differentiation is the primary need. Teachers who work with:

• mixed reading levels in the same class
• ELL or multilingual learners
• students who need scaffolded access to grade-level content

will find Diffit more useful than a general-purpose AI platform that treats differentiation as one of many features.

Where it is weaker

Diffit does not do lesson planning, rubric building, IEP drafting, or feedback workflows. If you need those, you will need other tools. Many teachers pair Diffit with MagicSchool AI or Eduaide.AI for planning and use Diffit specifically for reading-level adaptation.

Privacy and compliance

Diffit publicly presents itself as FERPA-aligned and low-friction for school deployment. AIForEdu reviewed the public documentation, but district teams should still request current privacy terms, implementation details, and approval references before adoption.

Who should use Diffit?

Best fit

Diffit is a strong fit if:

• differentiation is one of your most frequent weekly tasks
• you work with mixed reading levels or ELL students
• you want depth in one workflow more than breadth across many
• budget is tight and you want maximum value for one specific need

Less ideal fit

Diffit may be less ideal if:

• you need one platform for lesson planning, rubrics, IEPs, and more
• differentiation is a rare or occasional need
• you prefer an all-in-one tool like MagicSchool AI

Our verdict

Diffit addresses a real and common classroom need: differentiation at speed. The free tier is practical for occasional use, and the paid tier at $34.99/year is accessible enough for broader teacher adoption. It is strongest when a school needs a focused reading-support tool rather than an all-in-one AI platform.

Rating: 4.5/5 — Best-in-class for reading differentiation.
