Bottom line: Diffit’s free Basic plan does the one job it is built for — turning whatever you are teaching into classroom-ready reading at the level your students can actually handle — with PDF downloads, printing, and editing included at $0. The catch is history and reach: free accounts only keep content from the last 90 days, and the exports, standards alignment, and graphic organizers live on the paid Schools plan.
Diffit is an AI differentiation tool for teachers. You start from a topic or source material and get a ready-to-use reading resource adapted to your chosen level, which you can edit, adapt, or extend before handing it out. Diffit pitches it at mixed-ability classrooms — ELL, SPED, intervention, and MTSS contexts are named on its pricing page — with print-optimized layouts for teachers cutting screen time. There are no student logins and no student-facing AI: the teacher makes the material, the students read it. This review is based on Diffit’s published plan details, checked October 26, 2026.
What’s actually free on Diffit?
Diffit’s own pricing page lists Basic (free) as:
- Quality, classroom-ready content for anything you’re teaching
- Download to PDF, print, or share with colleagues
- Edit, adapt, or extend resources
- Access to content made in the last 90 days
That is a genuinely usable free plan for a working teacher: the core levelling workflow, a way to get the result onto paper or into a PDF, and editing are not paywalled. What free does not include is spelled out by what the Schools plan adds: export to Google, Canva, Microsoft and other formats, alignment to standards, skills, MTSS tiers and DOK levels, resources grounded in your core curriculum, the complete resource history, pre-made graphic organizers, and an admin dashboard with professional development and dedicated support.
How much does Diffit cost if you pay?
Diffit for Schools is a flat-rate annual subscription tiered by student enrollment, with unlimited premium access for all staff. Individual teacher licenses are also available; current listings put one at $14.99 a month or $149.99 a year. If you only differentiate a few readings a week, free plus PDF export may be all you need — the paid jump is mainly exports, alignment, and never losing your history.
Pros and cons of the free plan
Pros
- The core job — leveled, classroom-ready reading — is free, not a timed trial
- PDF download, printing, and sharing are included on Basic
- Print-optimized layouts suit classrooms trying to reduce screen time
- No student logins and no student AI; Diffit says it collects no student data and is FERPA and COPPA compliant
Cons
- Free content access stops at the last 90 days — older resources need the Schools plan’s full history
- One-click exports to Google, Canva, and Microsoft formats are paid
- Standards, skills, MTSS, and DOK alignment are paid features
- It is a single-purpose tool: reading differentiation, not a full lesson-planning suite
Who is Diffit’s free plan best for?
Teachers whose classes read at several levels at once — a mainstream class with ELL and SPED students, an intervention group, or anyone tired of rewriting the same passage three ways by hand.

Students studying the material afterwards may prefer Knowt, free for flashcards and notes, and research-heavy classes are covered in our NotebookLM free-tier explainer.
Frequently asked questions
Is Diffit really free?
Yes. Basic is a free plan, not a trial: leveled content creation, editing, PDF downloads, printing, and sharing are included, with access to content from the last 90 days.
What does Diffit for Schools add?
Exports to Google, Canva, and Microsoft formats, alignment to standards and DOK levels, complete resource history, graphic organizers, an admin dashboard, professional development, and dedicated support, for all staff under one flat-rate license priced by enrollment.
Do students need Diffit accounts?
No. Diffit has no student logins and no student AI. Teachers create the resources and share or print them; Diffit says it does not collect student data.
Verdict: Diffit Free is one of the clearest $0 offers in teacher AI: the main workflow works, paper output is included, and the limits (90-day history, paid exports and alignment) are easy to understand before you commit. Teachers in mixed-level classrooms should try Basic before paying for anything.
