How do you explain a contract clause to someone still learning English? Does simplifying it mean losing the dates that actually matter? ESL Simplifier rewrites English text at the level your reader has reached, using vocabulary they are likely to know.
Short answer: ESL Simplifier is a free tool on EizTools that rewrites English for language learners. Choose a reader level from beginner to advanced, cap the vocabulary to common words, and it returns text that keeps the meaning at that level.
What is ESL Simplifier?
ESL Simplifier adapts English for people learning it. That is a narrower job than plain English writing, and it needs different controls. A learner at A2 has a fairly predictable vocabulary, so the useful question is not whether text is simple but whether it stays inside the words that reader already owns.
Hence the vocabulary settings. Capping a rewrite to the most common thousand words is a real constraint with a real effect, and it is what separates this from generally shortening your sentences.
How Does ESL Simplifier Work?
Paste the English text into the prompt box, and say what it is for if that matters. Simplifying a contract clause for a B1 learner while keeping the key dates intact is a brief the tool can follow precisely.
The settings underneath hold four dropdowns and four switches. Reader Level and Keep Vocabulary do most of the work together. When the result arrives, Listen matters more here than in most tools: learners benefit from hearing text as well as reading it, and the read aloud version is free with every generation.
A Worked Example
Take a sentence from a tenancy agreement: The tenant shall be liable for any damage occasioned to the premises howsoever caused, excepting fair wear and tear.
Set Reader Level to Intermediate, Keep Vocabulary to Common 2000 Words, Sentence Style to Very Short Sentences, glossary on, and Keep original meaning exactly on. What comes back is two or three short sentences explaining that the tenant pays for damage they cause, that normal ageing does not count, with the legal terms listed underneath and explained. The obligation survives. The vocabulary does not.
Key Features
Levels that mean something
Reader levels follow the familiar A1 to C1 bands, so the setting matches how courses are already organised.
Vocabulary caps
Limit the rewrite to the most common thousand or two thousand words, which is a real constraint rather than a hint.
Glossary or inline notes
Hard words can be collected into a glossary or explained where they appear, whichever suits the lesson.
| Option | What it controls | Suggested value |
|---|---|---|
| Reader Level | Grammar complexity and assumed vocabulary | The level being taught, not the one being aimed at |
| Keep Vocabulary | The word list the rewrite may draw on | Common 2000 Words for most classroom use |
| Sentence Style | The shape of the output | Very Short Sentences for beginners, Plain English above B1 |
| Reading Difficulty | Very Simple through to Near Original | Simple, then adjust after seeing one result |
Note Topic Terms Only is the setting teachers overlook. It keeps the specialist vocabulary a learner needs for the subject while simplifying everything around it, which is exactly right for teaching content in a second language.
Common Mistakes
- Choosing a level above the class because the text feels too basic to you
- Simplifying legal or medical wording and then treating the plain version as the binding one
- Turning on both a glossary and inline definitions, which doubles the interruptions
- Forgetting Keep original meaning exactly on text where a condition really matters
For long source material, cutting it down before simplifying usually gives better results, since a learner reading a shortened text at the right level does better than one facing ten pages of it. The Text Summarizer handles that first step.
EizTools costs nothing, asks for no account and imposes no daily limit, which suits a teacher preparing several versions of one text for different groups. ESL Simplifier keeps the engine switchable between runs, worth remembering when a rewrite comes back technically simple but oddly unnatural.
Frequently Asked Questions
Can it produce a bilingual version?
Yes. The Output Language dropdown includes a bilingual option that pairs the simplified English with a translation, which helps learners check their understanding without leaving the page.
Does simplifying change the meaning?
It should not with Keep original meaning exactly switched on. Read the result against the original for anything legal or medical, since a lost condition is easy to miss and expensive to discover later.
Which level should I choose?
The level your reader is at now, not the one they are working towards. Text slightly below a learner builds fluency. Text above them builds avoidance.
Can I keep technical terms in the text?
Set Keep Vocabulary to Topic Terms Only and turn on inline definitions. The specialist words stay, everything else simplifies, and each term is explained the first time it appears.
Simplifying for a learner is not the same as writing simply. The measure is whether this particular reader can follow it with the English they already have. Paste your text above, set the level honestly, cap the vocabulary, and check that nothing important disappeared on the way down.
