Quick Answer
Paste formal or complex text and the tool makes it plainer by swapping long words for simpler ones — utilize becomes use, commence becomes start, numerous becomes many — using a fixed dictionary. It also breaks some long sentences at and, but and so. It is a rule-based tool, not a language model, and runs in your browser.
What the Text Simplifier Does
This makes text easier to read by replacing a set of long or formal words with shorter everyday ones, drawn from a fixed dictionary. Words like utilize, commence and approximately become use, start and about.
It also splits some long sentences by turning a comma before and, but or so into a full stop. It only touches words on its list and does not understand your text — it is not a language model.
How It Works
Paste your text and run it.
The tool replaces each word it recognises from its plain-English dictionary with the simpler equivalent, matching whole words only.
It then breaks long sentences where a comma is followed by and, but or so, and tidies spacing. The simpler text is ready to copy, all in your browser.
Generation algorithm
- Match dictionary words. Each word on the built-in list is found as a whole word.
- Swap for simpler words. The match is replaced with its shorter everyday equivalent.
- Split long sentences. A comma before and, but or so becomes a full stop.
- Tidy and output. Spacing is normalised and the simpler text is ready to copy.
Example simplifications
utilize → use · commence → start · terminate → end
approximately → about · numerous → many · sufficient → enough
facilitate → help · regarding → about · obtain → get
in order to → to · due to the fact that → becauseWorked example
We will utilize numerous resources in order to commence becomes We will use many resources to start.Only words on the dictionary are changed. A long word that is not listed is left as you wrote it.
Privacy
Your text is processed entirely in your browser — there is no server, no API call, and nothing is uploaded.
Because it runs locally with no AI model in the cloud, even confidential text stays on your device.
No account, no stored copy; the result is gone when you close the tab.

Standards & references
- Plain language — Replacing long, formal words with short everyday ones is core plain-English guidance for readability.
- Not a language model — It applies a fixed dictionary of swaps, not AI rewriting; it cannot judge meaning or simplify words it does not know.
Accuracy & Limitations
It only swaps words on its dictionary. Around nineteen long words and phrases are covered; any other complex word is left unchanged. It is a quick first pass, not a full readability rewrite.
It matches whole words, so it will not simplify a word it has not been given, and it cannot judge whether a swap fits — read the result to be sure the simpler word reads naturally in place.
It splits a long sentence only where a comma is directly followed by and, but or so. Other long sentences are left intact.
It is not a language model: it cannot rephrase, shorten ideas, or explain jargon. For deeper simplification, use a readability tool or a language model.

When to use it — and when not to
Good for
- Swapping common formal words for simpler ones
- A quick plain-English first pass
- Private, instant simplifying
Not the best choice for

Frequently Asked Questions
How does it simplify?
It swaps long words for simpler ones from a fixed dictionary, such as utilize to use and numerous to many.
Is this AI?
No. It is a fixed word-replacement list, not a language model, and it does not understand the text.
How many words does it cover?
About nineteen long words and phrases. Any complex word outside the list is left unchanged.
Does it split sentences?
Yes, where a comma is directly followed by and, but or so, it turns that comma into a full stop.
Will it simplify a word not on the list?
No. Unlisted words are left exactly as written, so it is a starting pass rather than a complete rewrite.
Could a swap read oddly?
Possibly. It cannot judge fit, so check that the simpler word suits the sentence after the swap.
Does it change meaning?
The swaps are near-synonyms, so the meaning is preserved, but it is worth a quick read to confirm.
How is it different from the paragraph rewriter?
The paragraph rewriter removes filler like 'very'. This tool swaps complex words for simpler ones and splits some long sentences.
Does it lower a measured reading level?
Usually a little, by shortening words and sentences. For the actual score, use the readability checker.
Is my text uploaded?
No. It runs entirely in your browser, with nothing sent.
Is it repeatable?
Yes. The same text always simplifies the same way, because the dictionary is fixed.
What gives deeper simplification?
A readability tool for measuring, or a language model for genuinely rewriting in simpler language.
