ReadWorks vs Goblin Tools: Which Is Better for Teachers?

ReadWorks and Goblin Tools solve completely different problems, so "better" depends on the job. ReadWorks is a free, nonprofit library of curated reading-comprehension passages and question sets. Goblin Tools is a set of AI micro-tools that break tasks into steps and adjust tone. For reading instruction, ReadWorks wins; for executive-function support, Goblin Tools wins.

Quick Answer: These tools aren't rivals — they're complements. Use ReadWorks to build reading comprehension with leveled passages and questions. Use Goblin Tools to break down assignments, scaffold executive function, and check tone. Many teachers keep both open in different browser tabs for different jobs.

Reading is in trouble, and executive function is the quiet reason many students can't show what they know. The 2024 National Assessment of Educational Progress (NAEP, 2024) recorded declines in reading for both 4th and 8th graders, with scores near their lowest in decades. At the same time, classrooms are more neurodiverse than ever: the CDC (2024) reports that roughly one in nine U.S. children has been diagnosed with ADHD.

Those two facts point at two different tools:

• ReadWorks targets the comprehension gap with content.
• Goblin Tools targets the "I don't know where to start" gap with structure.

Comparing them, then, is less "which is better" and more "which problem are you solving today." This guide is for K–9 teachers and coordinators trying to spend limited time wisely. If you want the full category map first, our 2026 Buyer's Guide to AI education tools sets the context; here we get specific about these two.

Two Tools, Two Very Different Jobs

The single most useful thing to understand is that ReadWorks and Goblin Tools barely overlap. One is a curated content library; the other is a suite of AI utilities. They show up in the same search because both are teacher-loved and free-ish, not because they compete.

Here is the honest split:

• ReadWorks — a what. A library of expert-written reading passages, paired texts, and comprehension questions, with a platform to assign and auto-score them.
• Goblin Tools — a how. A set of small AI tools that take a task or a message and restructure it — into steps, a calmer tone, or a time estimate.

Content vs. process

ReadWorks gives you material; Goblin Tools changes how work gets done. If your lesson needs a passage on volcanoes with questions, that is a content need — ReadWorks territory. If a student is paralyzed by a five-part project, that is a process need — Goblin Tools territory. Naming which you have prevents the classic mistake of expecting one tool to do the other's job.

Why they're often mentioned together

Both spread through teacher word-of-mouth, and both are cheap or free. That shared reputation lands them on the same "must-try free tools" lists. But a recommendation list is not a feature comparison — and treating these two as interchangeable leads to disappointment on both ends.

ReadWorks: A Free Library for Reading Comprehension

ReadWorks (readworks.org) is a nonprofit provider of free K–12 reading-comprehension content. It offers thousands of curated, human-written passages, paired texts, article sets, vocabulary support, and question sets — plus a digital platform to assign work and auto-score most questions. Everything is free, funded by donors rather than subscriptions.

Its design rests on reading science. Cognitive researcher Daniel Willingham has long argued that comprehension depends heavily on background knowledge, not just decoding skill. ReadWorks leans into that: its content is organized to build knowledge and vocabulary across science, social studies, and literature.

What's inside ReadWorks

ReadWorks is broad but organized, and a few features do the heavy lifting. For most teachers, these are the ones that matter:

• StepReads — leveled versions of the same passage, so a class can read one topic at different reading levels.
• Question sets — comprehension and vocabulary questions with answer keys, many auto-scored on the digital platform.
• Paired texts — two readings on one topic for synthesis and comparison.
• Audio read-aloud — supports early readers and students with decoding difficulties.
• Article-A-Day — a routine designed to build knowledge and reading stamina in short daily doses.

Why "free and nonprofit" matters

ReadWorks removes the budget barrier entirely, which changes how you can use it. Because there is no paywall, you can assign generously, use it across a whole grade, and build routines without justifying a purchase. For under-resourced schools especially, a free, standards-aligned reading library is a genuine equity lever.

Where ReadWorks stops

ReadWorks gives you what's in the library — no more, no less. Its honest limits are worth stating plainly:

• You take what exists. If the exact passage you want isn't there, you can't generate one; the content is curated, not AI-made.
• It's reading-centric. It won't help with math scaffolding, project planning, or task breakdown.
• It's U.S.-oriented. Passages and standards alignment center on U.S. contexts.

For a workflow that generates original leveled passages and differentiated question sets on any topic, that is a different tool category — see EduGenius vs Diffit, which covers generative differentiation in depth.

Goblin Tools: AI Micro-Tools for Getting Started

Goblin Tools (goblin.tools) is a small collection of single-purpose AI tools, originally built to help neurodivergent people with executive function. Created by developer Bram De Buyser, it is deliberately tiny and friendly: each tool does one thing, fast. Teachers have adopted it well beyond its original audience.

The flagship is Magic ToDo, which takes any task and breaks it into steps. A "spiciness" setting — shown as chili peppers — controls how granular the breakdown gets, from a light outline to painstaking micro-steps.

The Goblin Tools lineup

Each tool targets a specific executive-function friction point. The set is small enough to learn in one sitting:

• Magic ToDo — breaks a big task into ordered subtasks; adjustable granularity.
• Formalizer — rewrites text to change tone (more formal, more polite, less blunt).
• Judge — reads a message and estimates its emotional tone and subtext.
• Estimator — gives a rough time estimate for a task.
• Compiler — turns a messy brain-dump into a structured list.

For your own teacher workflow

Goblin Tools quietly supports the administrative side of teaching. A few realistic, hypothetical uses:

• Paste a tricky parent email into Judge before you reply, to sanity-check its tone.
• Run your own reply through Formalizer to soften a frustrated first draft.
• Drop "run the science fair" into Magic ToDo to turn a vague obligation into a checklist.

For student executive function

Goblin Tools shines as a scaffold for students who freeze at "start." Say you teach Grade 7 and assign a research project. A student who feels overwhelmed could run the assignment through Magic ToDo to see it as a sequence of small, doable steps — a support that is especially meaningful for learners with ADHD or autism, echoing the executive-function scaffolding that Harvard's Center on the Developing Child describes as learnable, not fixed.

Where Goblin Tools stops

Goblin Tools is a helper, not a curriculum — and it has real caveats. Keep these front of mind:

• It creates no instructional content. No passages, no lessons, no assessments.
• It's AI, so outputs vary. Steps and estimates are suggestions to review, not gospel.
• Privacy needs care. Because you paste text into an AI service, never enter student names or personal data. Review the compliance questions in Is ChatGPT FERPA compliant? before pasting anything sensitive.

Accessibility: What Each Tool Offers Diverse Learners

Through a Universal Design for Learning (UDL) lens, the two tools cover different principles — and together they cover more. CAST's UDL framework asks for multiple means of representation, engagement, and action and expression. ReadWorks and Goblin Tools each land on a different principle.

Mapping them clarifies why they pair so well:

• Representation — ReadWorks. Audio read-aloud, StepReads leveling, and vocabulary support lower the barrier to accessing text for struggling and emerging readers.
• Action and expression — Goblin Tools. Task breakdown and time estimates lower the barrier to starting and organizing work, which is where executive-function challenges bite hardest.
• Engagement — you. Relevance, choice, and relationship remain the teacher's domain; no tool substitutes for them.

Why this matters for neurodiverse classrooms

Executive function is learnable, not fixed. Harvard's Center on the Developing Child describes executive-function skills — planning, sequencing, getting started — as capacities that develop with scaffolding and practice. Goblin Tools externalizes that scaffolding: a Magic ToDo breakdown models the very sequencing a student is still building.

Meanwhile, ReadWorks's audio and leveled options remove decoding barriers so a student's comprehension isn't capped by fluency. Used together, they support both the "read it" and the "do it" sides of an assignment — a practical, low-cost expression of UDL for a mixed-needs room.

Head-to-Head Comparison

The table makes the "different jobs" point concrete. Read across the rows and the contrast is obvious — there is almost no dimension on which these tools are trying to do the same thing.

The takeaway from the table: the only row where they touch is "free-ish and teacher-loved." Everything else diverges — which is exactly why the right answer is usually "both, for different reasons."

Where a generative tool fits alongside both

Sometimes you want neither a fixed library nor a task splitter — you want custom material. That is a third category. A generative platform like EduGenius can create original leveled passages with comprehension questions when the library doesn't have your exact topic, and it can produce concept revision notes or step-by-step scaffolds when a task needs structure.

EduGenius is credit-based, so cost stays predictable: new users start with 25 welcome credits, some legacy users retain 100, and paid plans run $7.99/month (Starter, 500 credits) to $15.99/month (Professional, 1,000 credits). Think of it as the "make it yourself" option that sits between ReadWorks's fixed library and Goblin Tools's process helpers.

Getting Started: Setup and Learning Curve

Both tools are easy to start, but they onboard differently. ReadWorks is an account-based platform you set up once and return to; Goblin Tools is a no-login web utility you open the moment you need it. Neither demands training.

Here is what adoption actually looks like:

• ReadWorks — create a free teacher account, set up classes, and browse or search the library. The learning curve is in finding the right content and building assignment routines, not in using the tool.
• Goblin Tools — visit the site, pick a tool, paste your text. There is essentially no setup; the only "skill" is learning which of the five tools fits your moment.

Accounts, devices, and the classroom fit

Think about where each tool lives in your day. ReadWorks fits a scheduled reading block, on student devices, with work assigned and auto-scored. Goblin Tools fits the messy in-between moments — planning a project, drafting a reply, scaffolding a stuck student — often on your own screen rather than every student's.

• ReadWorks: best as a routine students return to.
• Goblin Tools: best as an on-demand helper you reach for as needed.

A Week Where You'd Use Both

Because they solve different problems, a realistic week uses each without conflict. Here is a hypothetical Grade 6 sequence — no invented results, just how the tools slot together around one unit on ecosystems.

1. Monday — build knowledge (ReadWorks). Assign a StepReads passage on food webs so every reader accesses the same topic at their level, with an auto-scored question set.
2. Tuesday — daily reading routine (ReadWorks). Run an Article-A-Day reading to grow background knowledge and stamina.
3. Wednesday — launch a project (Goblin Tools). Introduce a "design a habitat" project; students who feel overwhelmed run it through Magic ToDo to see the steps.
4. Thursday — support a stuck student (Goblin Tools). For a learner frozen at "start," adjust the spiciness for finer steps and pair it with a check-in.
5. Friday — synthesize (ReadWorks paired texts). Use two readings on ecosystems for a compare-and-synthesize task.

The division of labor

Notice the pattern: ReadWorks carries the reading; Goblin Tools carries the doing. Neither steps on the other. That clean separation is why "keep both" is not a cop-out answer — it reflects how differently the two tools function inside a single week.
