Diffit Review 2026: A Useful Classroom Tool That Doesn't Know Australia Exists

The verdict: Diffit solves a real problem. Any teacher who has spent an afternoon rewriting a Year 8 science article into three reading levels will understand exactly why this tool has spread through staffrooms. Paste a URL or a block of text, pick a grade level, and get a differentiated reading passage with vocabulary, comprehension questions, and a summary in under ten seconds. It does that one thing better than anything else available. Where it falls down for Australian educators is almost everything around the edges: US-dollar pricing, US-based data storage, standards alignment locked to CCSS and US state frameworks, and zero ACARA integration. It will not charge you in AUD, it will not align to the Victorian Curriculum or the Australian Curriculum, and it will not keep your data in Australia. If you teach in Australia and you want a differentiation tool, Diffit is still worth using — but go in clear-eyed about what it is and what it is not. Score: 14/25 — Good.

What it is

Diffit is an AI-powered platform built specifically for teachers. You give it a piece of text — an article URL, a PDF, a block of pasted prose, a YouTube video transcript, or just a topic prompt — and it generates a classroom-ready reading passage adapted to a target reading level (grade 2 through roughly grade 11), complete with a vocabulary list, comprehension questions, an open-ended discussion prompt, and a summary.

The company behind it is Diffit, Inc., headquartered in Berkeley, California. The team describes itself as "former educators, school leaders, and employees of leading ed-tech companies." The product is squarely aimed at K–12 teachers who need to differentiate instruction — giving struggling readers an accessible version of the same content that higher-level readers encounter in the original.

The core workflow: a teacher pastes in a news article about the water cycle, selects "Grade 4," and within ten seconds has a version their lower-level readers can actually access — with ten vocabulary words, six comprehension questions, and a short summary already drafted. Do it again at "Grade 7" for the class's stronger readers. The teacher then edits, exports, and distributes. That is the entire product. It is not trying to be anything else.

What it costs in Australia (AUD + GST)

Diffit prices exclusively in US dollars. There is no AUD billing option and no Australian-specific pricing. Diffit's pricing pages say nothing about GST or tax for Australian purchasers, so whether GST is added at checkout is not something we can confirm from the company — check the figure at the point of purchase.

Currency note: The AUD figures above are a straight currency conversion at approximately 1.40 AUD per USD as of September 2026, not GST-inclusive prices. Diffit does not state how GST is treated for Australian purchasers buying in USD, so treat the AUD column as an indicative conversion only and confirm the final charge at checkout. Individual plans are credit-card only; school/district plans accept purchase orders.

First-year teachers: Diffit offers the full premium version free to teachers in their first year of teaching. 60-day trial: all new accounts receive 60 days of premium access automatically — a genuine offer, not a capped feature trial.

The free tier is more useful than most. Unlimited reading-level adaptations with PDF export means a teacher can use the core product indefinitely at no cost. The paywall sits around export to Google and Microsoft tools, standards tagging, and the Diffit Chat feature for refining outputs conversationally.

How it works / features

Inputs: Diffit accepts plain text (paste directly), article URLs, uploaded PDFs, YouTube video transcripts, and topic prompts (type "the gold rush" and it generates source text from scratch). This covers most of what a classroom teacher actually wants to throw at it.

Reading levels: Adaptation runs from approximately Grade 2 through Grade 11, roughly equivalent to Years 2–11 in Australian schools. You pick a level, Diffit restructures the text — not just swapping in simpler synonyms, but rewriting sentence structure and adding context clues while preserving key concepts.

Languages: The platform supports 70+ languages for translation and adaptation. This is genuinely useful in Australian schools with significant EAL/D cohorts — you can produce a Simplified English version and an Arabic version of the same passage in two button clicks.

Outputs per passage: Each adaptation ships with a vocabulary list (key terms with definitions), multiple-choice comprehension questions, open-ended discussion questions, and a text summary. Premium adds graphic organisers (Frayer model vocabulary slides, 3-2-1 summaries, and other scaffolding templates), standards alignment tagging, and DOK (Depth of Knowledge) level indicators.

Diffit Chat (premium): An in-platform conversational tool. You can ask it to adjust reading level, change the tone, add more questions, or shift the focus of a passage without starting over.

Export (premium): Google Docs, Google Slides, Google Forms, Google Classroom, Microsoft Word, Microsoft PowerPoint — or PDF (free). The export-to-Google-Classroom function is the feature most teachers cite as the reason they upgrade.

Standards alignment (premium): Supports CCSS (Common Core), NGSS (Next Generation Science Standards), and all 50 US state standards frameworks. There is no ACARA support and no Australian Curriculum alignment. Australian teachers cannot tag content to Victorian Curriculum, NSW Syllabus, or any other Australian framework.

What it does well

Speed is the headline. A task that takes an experienced teacher 20–30 minutes — rewriting a passage at two or three reading levels — takes Diffit under 15 seconds. That is not a marginal improvement. For a teacher managing 28 students at three to four different reading levels across multiple subjects, this compounds into hours reclaimed per week.

The quality of the adaptation is better than expected. Generic AI tools (ChatGPT, Gemini) will simplify text if you prompt them carefully. Diffit's output is more consistent and more structured for classroom use — the vocabulary lists are curated, the questions follow a pedagogical pattern, and the formatting arrives ready to hand to students rather than requiring a round of cleanup.

The free tier is genuinely functional. Unlimited adaptations with PDF export is a real product, not a teaser. An Australian teacher on a school budget can use Diffit every day and pay nothing. The upgrade is about workflow convenience (Google Classroom export) rather than gating the core function.

EAL/D support is real. Translation into 70+ languages, combined with reading-level adaptation, means Diffit addresses one of the most time-consuming parts of teaching in diverse Australian classrooms. A refugee student arriving mid-year with limited English is not an edge case in many Australian schools — it is a regular event. Diffit handles this without requiring the teacher to be a linguist.

Student data is not collected. Teachers log in; students do not. No student names, ages, or identifiers enter the system. This is the correct model for K–12 edtech and it matters for school adoption decisions.

Where it falls short

The scope is narrow by design, and that cuts both ways. Diffit does reading differentiation. It does not do lesson planning, assessment generation, report writing, rubric creation, or anything beyond adapting text. If you want an AI teaching assistant, Diffit is not it. If you want differentiated reading materials, there is nothing better — but be clear about what you are getting.

Standards alignment is US-only. Australian teachers cannot tag resources to the Australian Curriculum (ACARA), the Victorian Curriculum, the NSW Syllabus, or any Australian framework. The premium feature that tags content to learning standards is entirely US-centric. Australian teachers who need curriculum documentation will have to do that alignment manually.

No Google Classroom export on the free tier. For Australian primary and secondary schools where Google Workspace for Education is the dominant platform — which it is in most states — the inability to push directly to Classroom without paying is a significant friction point. The workaround is downloading the PDF and uploading it manually. It works, but it adds steps.

Comprehension questions lean toward recall. The automatically generated questions tend to sit at the lower end of Bloom's Taxonomy — what happened, who was involved, what does this word mean. Higher-order questions (evaluate, synthesise, create) need to be written by the teacher or coaxed out via Diffit Chat (premium). For secondary teachers preparing students for extended-response assessments, the default output needs supplementing.

Accuracy requires checking. When you prompt Diffit with a topic and ask it to generate the source text (rather than adapting text you supply), the platform creates that content from scratch via AI. That content can contain errors. The company explicitly notes that outputs should be reviewed before classroom use. This is standard and reasonable advice, but it means the tool is not a hands-off resource generator — teacher review is not optional.

No maths, no media-only tasks. Diffit is a reading tool. It cannot help with numeracy differentiation, it cannot process an image, and it cannot adapt a diagram. Science, HASS, and English teachers will find it immediately useful. Maths teachers will not.

Australian fit

This is where Diffit's limitations become concrete for Australian educators.

Currency and billing: Prices are in USD only. An individual subscription costs US$14.99/month (~A$21/month) or US$149.99/year (~A$210/year). There is no AUD option. Diffit does not state whether Australian GST is added at checkout, so verify the final charge at the point of purchase rather than assuming the conversion above is what you will pay.

Data residency: All data is processed and stored in the United States. Diffit's privacy policy states explicitly: "Your Personal Data will be processed and stored in the United States." There is no Australian or Asia-Pacific data centre. For Australian state government schools with strict data sovereignty requirements, this is a compliance question worth raising with your IT department before deploying at scale.

Curriculum alignment: Diffit's standards engine covers CCSS, NGSS, and all 50 US state curriculum frameworks. It does not include ACARA, the Victorian Curriculum, the NSW Syllabus, or any other Australian framework. Australian teachers using the premium plan get standards tagging that means nothing in an Australian school context.

Australian support: No local support presence. No Australian phone line, no AEST business-hours support. The help centre is US-based. Contact is via web form.

Australian-aware content: When you ask Diffit to generate reading passages from a topic prompt, the content is US-oriented by default. Ask for a passage about "local government" and you will get something that reads like it was written for a New England civics class. Teachers need to supply Australian source material rather than using Diffit to generate it from scratch.

What this means in practice: Diffit is a useful tool in Australian classrooms. It works. But it is a US product that happens to be usable in Australia, not a tool built with Australian teachers in mind. The free tier reduces the stakes — no AUD billing means no financial exposure if you choose to walk away.

Score

★★★ Good (14/25)

Australian Fit gate: Diffit scores 2/5 on Australian Fit — below the 4/5 a tool needs for ★★★★★ Excellent or a category Top Pick, so it could never be crowned for an Australian audience. But the gate only removes the top star; it never lowers a tool below its scored band. At 14/25, Diffit sits in the three-star Good band on the maths. See our methodology.

Bottom line

If you are an Australian primary or secondary teacher who spends time rewriting texts at multiple reading levels: Try Diffit on the free plan today. It will save you real time, the free tier does not expire, and you do not need to hand over a credit card. PDF export is enough to make it useful.

If you teach in a school where Google Workspace is the standard platform: You will feel the friction of the free tier quickly. Pushing adapted content directly to Google Classroom requires the paid individual plan (~A$21/month or ~A$210/year). Whether that is worth it depends on how much differentiation you do. For teachers differentiating daily, it probably is.

If you need your school's data to stay in Australia: Diffit is not the right choice at scale. Data is stored in the US. Raise this with your school's IT and privacy officer before proceeding with a school-wide licence.

If you are a maths teacher, a STEM teacher who works primarily with diagrams, or a teacher looking for a general AI teaching assistant: Diffit will not help you. Look elsewhere.

If your school is evaluating a formal curriculum documentation tool: Diffit's standards alignment feature is US-only. It will not map to ACARA or state-level frameworks. That is a hard gap for Australian school leaders managing curriculum documentation requirements.

Frequently asked questions

Is Diffit available in Australia?

Yes — it works in Australian classrooms, with reading levels mapping roughly to Years 2–11 and translation across 70+ languages for EAL/D students. But it's a US product (Diffit, Inc., Berkeley, California) that happens to be usable here, not one built with Australian teachers in mind.

Does Diffit charge in AUD?

No. Diffit bills in US dollars only, with no AUD option — Individual Teacher is US$14.99/mo (~A$21) or US$149.99/yr (~A$210). GST treatment for Australian purchasers isn't stated, so confirm the final charge at checkout.

Is there a free plan?

Yes, and it's genuinely functional — unlimited reading-level adaptations with PDF export, no expiry, no credit card. The paywall sits around Google/Microsoft export, standards tagging and Diffit Chat. New accounts also get 60 days of premium, and first-year teachers get premium free.

Does Diffit align to the Australian Curriculum?

No. Standards alignment covers CCSS, NGSS and all 50 US state frameworks only — there's no ACARA, Victorian Curriculum or NSW Syllabus support. Australian teachers must do curriculum documentation manually.

Is student data stored in Australia?

No. All data is processed and stored in the United States, with no Australian or Asia-Pacific data centre. Note teachers log in but students don't, so no student identifiers enter the system. For state schools with data-sovereignty rules, raise it with IT before a school-wide rollout.
