Differentiation shows up on nearly every AI-tools-for-teachers list, but “differentiate this reading” means very different things depending on which tool you type it into. Diffit was built to do exactly one job — take a text and produce leveled versions of it — and does that job better than either of the two generalist tools that also claim to handle it.
MagicSchool and ChatGPT can both differentiate a text if you ask them to. The question worth answering before you pick one isn’t “which is smartest” — it’s whether you want a dedicated tool built around this one task, or a broader tool where differentiation is one request among many things it can do.
The Quick Answer
Diffit is the specialist — paste in a text or topic and get multiple reading-level versions, vocabulary lists, and comprehension questions in under a minute, with a genuinely unlimited free tier for the core workflow. MagicSchool can differentiate too, but it’s one of 80+ tools, so the differentiation feature itself is thinner. ChatGPT can differentiate anything you ask it to, but you’re writing and refining the prompt yourself each time, with no leveled-output structure built in. If differentiation is a regular, recurring part of your week, Diffit is worth using even alongside a broader tool.
What Each One Actually Is
Diffit takes a source — a topic, an article, a PDF, even a YouTube URL — and generates reading-level-adjusted versions of it alongside vocabulary lists, comprehension questions, and graphic organizers, all in under a minute. The free tier is genuinely unlimited for this core workflow: leveled passages, questions, and vocabulary with no generation cap and no credit card. See our full Diffit review.
MagicSchool AI includes a differentiation tool among its 80+ teacher tools, alongside lesson planning, IEP writing, rubrics, and parent communication. It’s useful if you want one platform for everything, but because differentiation is a single feature among dozens, it doesn’t match Diffit’s depth on reading-level precision. See our full MagicSchool AI review.
ChatGPT has no dedicated differentiation feature at all — you write a prompt describing what reading level you want and what to include, and it generates a response. It works, and it’s flexible enough to handle requests no purpose-built tool has a button for, but every differentiated text starts from a blank prompt rather than a structured workflow.
Side-by-Side: Diffit vs MagicSchool vs ChatGPT
Diffit | MagicSchool | ChatGPT | |
|---|---|---|---|
Built for | Text differentiation specifically | 80+ general teacher tools | Open-ended prompting, any task |
Differentiation workflow | Structured — leveled outputs, vocab, questions | One feature among many | You write the prompt each time |
Free plan | Unlimited core workflow, no card needed | 80+ tools, standard usage limits | Free tier covers most tasks |
Paid plan | $14.99/mo (Individual Pro) | $8.33/mo (Plus) | $20/mo (Plus) |
Output structure | Leveled passages + vocab + questions + organizers | Varies by tool | Whatever you specify in the prompt |
Best for | Frequent, precise text differentiation | One platform for your whole workload | Open-ended tasks no other tool covers |
Where Diffit Wins
- Precision on reading level. Diffit is purpose-built for text leveling — the outputs are more consistently accurate to a target grade level than a general prompt to ChatGPT or a quick MagicSchool tool.
- Speed for a recurring task. If you differentiate texts weekly, a structured workflow beats writing a fresh prompt every time.
- Genuinely unlimited free tier for the core workflow — no generation cap, no credit card required.
- Built-in comprehension questions and vocabulary ship with every leveled passage, not as a separate step.
Where MagicSchool and ChatGPT Win
- One tool for everything else. If you already use MagicSchool for lesson plans, IEPs, and rubrics, using its differentiation tool too means one less login to manage — even if the output is thinner than Diffit’s.
- ChatGPT handles anything a specialist tool doesn’t. Neither Diffit nor MagicSchool covers every possible differentiation scenario — ChatGPT will attempt genuinely unusual requests a purpose-built tool has no button for.
- Fewer accounts to juggle. Adding a fourth or fifth specialist tool has a real cost in login fatigue, even when each individual tool is better at its one job.
The Same Article, Run Through All Three
Paste a grade-level news article into each tool and ask for a 3rd-grade-reading-level version with comprehension questions. Diffit hands back multiple reading levels of the same text side by side, plus auto-generated comprehension questions, vocabulary support, and a graphic organizer — in under a minute, purpose-built for exactly this task. MagicSchool can do a version of the same thing through its text leveler tool, but you’re picking one target level at a time rather than seeing several side by side. ChatGPT can do it too if you prompt it well (specify grade level, ask for comprehension questions explicitly), but you’re writing the prompt from scratch each time rather than using a purpose-built interface — see our ChatGPT prompts for teachers guide for ready-made differentiation prompts if you go this route.
Pricing at a Glance
Diffit’s free plan covers core differentiation with no limit on reading-level generation; Individual Premium is $14.99/month for Google Classroom export and standards alignment, with a custom-priced School plan for full staff access — see our full Diffit review for the complete pricing and feature breakdown. MagicSchool and ChatGPT for Teachers are both free for verified K-12 educators; see our MagicSchool AI review and ChatGPT for Teachers review for their respective free-tier details.

Do You Need All Three?
Realistically, most teachers land on one primary tool for daily use and keep the others as backups. A common setup: MagicSchool (or another all-in-one platform) as the default for lesson planning, rubrics, and general prep, Diffit specifically for text differentiation because the output quality difference is real and worth a second login, and ChatGPT on standby for the occasional task that doesn’t fit either tool’s structure. You don’t need to pay for all three — Diffit’s free tier and MagicSchool’s free tier both cover the core workflow without a subscription.
Which Should You Actually Use?
Choose Diffit if: differentiating texts by reading level is a regular part of your week and you want consistent, structured output without writing a new prompt every time. The free tier is generous enough to actually rely on.
Choose MagicSchool if: you want one platform covering differentiation alongside lesson planning, IEPs, and everything else, and you’re fine with differentiation being “good enough” rather than best-in-class.
Choose ChatGPT if: you need something more open-ended than either tool offers, or you’re handling a one-off request that doesn’t fit a structured differentiation workflow.
Frequently Asked Questions
For the specific task of producing accurate, consistently leveled reading passages, yes — Diffit was built around this one workflow, while ChatGPT requires you to specify and often re-specify reading-level requirements in the prompt, with less consistent results.
It covers the basics — generating a differentiated version of a text — but Diffit’s output is more consistently accurate to the target reading level, and Diffit adds vocabulary lists, comprehension questions, and graphic organizers as part of the same workflow.
It’s genuinely usable long-term — leveled passages, comprehension questions, and vocabulary lists are unlimited on the free tier with no credit card required. The $14.99/mo Pro plan adds unlimited generations beyond the free tier’s scope, Google Docs/Slides export, and the full activity library.
Yes, and many teachers do — MagicSchool for general lesson prep and Diffit specifically when a text needs to be leveled for different readers. Neither tool requires exclusivity.
ChatGPT, since it will attempt genuinely unusual requests that don’t fit either specialist tool’s built-in structure — at the cost of needing you to write and refine the prompt yourself.
Yes — alongside the leveled reading passage, Diffit auto-generates comprehension questions, vocabulary support, and a graphic organizer for the same source text, which is part of why it’s faster than prompting a generalist tool for the same result.
For a single teacher’s core differentiation needs, generally yes — the free plan has no limit on reading-level generation. The $14.99/month Individual Premium tier adds Google Classroom export and standards alignment, which matters more if you’re exporting materials regularly rather than using them directly in class.
It depends how much differentiation work you do. MagicSchool’s text leveler covers the basics, but Diffit is purpose-built specifically for this task and produces multiple reading levels plus comprehension questions faster. If differentiation is a daily need, Diffit’s free plan is worth adding even alongside MagicSchool.
