Simplify Any Text for English Learners
Paste an article, textbook passage, or directions, choose a WIDA level, and get a rewrite that preserves the academic content while removing the language barriers — shorter sentences, high-frequency vocabulary, idioms unpacked, pronouns named.
Built for busy teachers who need classroom-ready drafts fast.
What You Can Generate
- Five WIDA proficiency targets (Entering through Bridging) plus CEFR equivalents
- Pre-teach vocabulary table identifying Tier 2/3 words students still need
- Three calibrated comprehension questions to check understanding
- A "what changed" summary so you know exactly what was simplified
Why Comprehensible Input Means More Than Shorter Sentences
Krashen's comprehensible input hypothesis is foundational to ESL pedagogy: students acquire language when they understand messages just slightly above their current level. But "comprehensible" is not the same as "dumbed-down." A good simplification preserves the academic content, the author's meaning, and the intellectual challenge — it just removes the linguistic obstacles that keep an ELL student from accessing it.
That means concrete subject-verb-object structure for Entering-level multilingual learners, idioms replaced with literal meaning, pronouns referenced clearly, complex transitions broken into separate sentences, and Tier 3 content words preserved (because that's often what we're assessing). For Bridging-level students, near-grade-level complexity is fine; you only simplify the most opaque structures. The ESL Text Simplifier calibrates to the level you specify.
Where This Fits a Sheltered Instruction Lesson
In a SIOP-aligned lesson, the simplified text becomes the "input" stage of instruction. Students read it, you check comprehension, then they engage with the content using sentence frames or scaffolded discussion protocols. The Pre-Teach Vocabulary section maps directly to the SIOP "building background" component: explicitly teach 4-8 Tier 2 / Tier 3 words before students encounter them in context.
For inclusion teachers, this tool removes the time barrier to differentiation. Instead of skipping over a textbook chapter because half your class can't read it, you simplify it to the level your ELL students need. The Advanced students still get the original; your multilingual learners get an accessible version of the same content. That's differentiation done right.
Suggested Classroom Workflow
- Paste the original text — article, textbook passage, lab procedure, or set of directions.
- Choose the target WIDA level for your students.
- List any vocabulary you want preserved (key content words, named entities, terms being assessed).
- Generate. Review the simplified version against the original to verify accuracy.
- Pre-teach the flagged vocabulary, then have students read the simplified version with a comprehension scaffold.
Common Mistakes to Avoid
- Simplifying a text without pre-teaching the vocabulary that's still above level — the simplified version will still be incomprehensible.
- Using simplified text as a permanent replacement instead of a temporary scaffold — the goal is for students to access grade-level text eventually.
- Removing the academic content alongside the language complexity — preserving the intellectual demand is the whole point.
- Ignoring the comprehension check — without verifying understanding, you don't know if the simplification worked.

Frequently Asked Questions
How is this different from just summarizing a text?
A summary shortens content. Simplification preserves the full content but adjusts the language complexity. Your students still get all the information, just at an accessible level.
Can I use this for state-mandated assessments?
Most state assessments do not allow text simplification as an accommodation, but your IEP or EL Plan may permit simplified directions or a scribed read-aloud. Check your district's testing accommodations policy. This tool is most useful for instructional materials, not standardized tests.
Does this work for adult ESL learners?
Yes. Choose "Adult / Newcomer" for grade band. Adult ESL students often need simplified workplace documents, government forms, and instructional text — this tool handles those well.
How does this compare to Lexile leveling?
Lexile is one measurement framework; WIDA is the dominant ELL proficiency framework. The two roughly correspond — WIDA 3 (Developing) maps to roughly 600-800L. We use WIDA labels because they're what most ESL/ELL/MLL teachers use day-to-day.
Can I keep certain words from being simplified?
Yes. The "Vocabulary to Preserve" input lets you list content-specific terms (e.g., "photosynthesis", "ecosystem", "Constitution") that should appear unchanged in the simplified text.
