Diffit
Rewrites any text, topic or video into reading material at each student’s level
About Diffit
Diffit does one thing: it takes a piece of source material and produces a version of it that a particular student can actually read. Give it an article, a URL, a topic, or a YouTube video, tell it the reading level you need, and it returns the text rewritten at that level along with a vocabulary list, comprehension and discussion questions, and graphic organizers built from the same content. Differentiation is the entire product, and the narrowness is deliberate.
The problem it addresses is one of the least tractable in a classroom. A single class contains students reading several years apart, the curriculum text is pitched at one level, and producing three versions of a reading by hand is the work nobody has time for. Teachers have historically solved this by not solving it. Diffit turns that job into a few seconds, which is why it spread by word of mouth among teachers rather than through district procurement. The company states it is trusted by thousands of schools and districts and backs its outcome claims with a third-party-evaluated survey of 2,517 teachers, which is more rigour than an edtech marketing page usually carries. The free tier is permanent and real, though pointed: you can create and print resources, but exports to Google and Microsoft, standards alignment and access to resources older than 90 days are all behind Premium.
You give Diffit a source. That can be a topic typed in plain language, a pasted article, a link to a web page, or a YouTube video. You set the reading level and the language, and Diffit generates an adapted passage at that level together with the supporting material: key vocabulary with student-friendly definitions, multiple choice and open response questions, a summary, and graphic organizers such as CER frames or Cornell Notes. Everything is editable, so a teacher who knows their class can adjust the vocabulary list or rewrite a question before it goes out. On the free tier you print or share from there. With Premium you export the set into Google Docs, Slides, Forms or Classroom, or into Microsoft, align the resource to a standard or curriculum, and reopen anything you have ever made rather than losing it after 90 days.

Teachers of reading-heavy subjects in mixed-ability classes, English language learner specialists, and special education teachers writing at several levels for the same lesson. Anyone who regularly retypes a text to make it accessible will get the time back immediately. It is genuinely narrow: if your subject is not built on reading passages, Diffit does very little for you, and a maths teacher will find the new maths support thin next to the core product. The free tier's 90 day history limit bites harder than it first appears, since the resources you most want to reuse are last year's. School and district pricing is quote-only, so only the individual teacher ladder is published. Not a developer tool in any sense.
