TL;DR
Diffit solves the single most painful classroom prep task — taking one source and making it accessible to a class with a 4-grade reading-level spread and three home languages. It's a 30-second job, free, and the output is usable as-is.
Recommend it if
You teach a mixed-level class, you have ELL students, or you're a parent translating a homework article for a kid still building English fluency.
Skip it if
You only ever assign textbook content (already differentiated), or your school district forbids using third-party content reformatters.

| Teachers | Sunday night — paste the week's news article, generate 4 versions (grades 4 / 6 / 9, plus Spanish), print or push to Classroom. | 6 min | 4 leveled handouts |
| Teachers | ELL student joins mid-unit — drop the current chapter into Diffit, send a Vietnamese version home with a parent-friendly summary. | 3 min | Translated chapter |
| Parents | Your 8th grader's social studies article is too dense — paste it into Diffit, drop it to 6th grade, read it together over dinner. | 2 min | Read-together version |

The 30-second workflow
- Paste an article URL, PDF or raw text
- Pick the target grade level (1-12)
- Optionally pick an output language (50+ supported)
- Get a printable worksheet: leveled passage, vocabulary, summary, comprehension questions
The Pro tier ($8/mo) removes the 5-per-day cap and adds bulk export. Most solo teachers stay on Free.
What we like
- + Levels any text to grades 1-12 in one click
- + Translates the leveled version into 50+ languages — gold for ELL classrooms
- + Auto-generates summary, key vocabulary, comprehension questions
- + Free tier covers most solo-teacher workloads
Heads up
- − Free tier caps at 5 generations per day
- − The level slider is heuristic, not Lexile-accurate — eyeball the output
- − Source attribution is the teacher's job; Diffit doesn't license content

Frequently asked questions
Frequently asked questions
Are the grade levels accurate?
They're heuristic — Diffit targets vocabulary complexity and sentence length rather than a strict Lexile score. For high-stakes assessment use Lexile; for daily classroom use, Diffit's levels are fine and most teachers eyeball them anyway.
Is it legal to paste copyrighted articles?
That's on you — same as photocopying a NYT article for class. Most US K-12 fair-use covers single-classroom-day use; check with your district. Diffit doesn't store or republish source content.
How is this different from ChatGPT?
ChatGPT can level a passage if you prompt it carefully. Diffit is purpose-built — one click, picks a sensible level by default, includes vocabulary, questions and translation in the same workflow. For mixed-level prep at scale, Diffit is faster.
Will it work for non-English source text?
Source has to be English right now. Translations are output-only — paste English, get Spanish back. Two-way is on the roadmap.
Does the worksheet auto-grade?
No. Diffit generates the questions; grading happens in your gradebook or Google Classroom. The multiple-choice answer key is on the teacher copy.
