Essay Simplifier
Turn dense academic prose into writing a marker can follow in one pass — without flattening the argument, losing the nuance, or stripping out the terms your field actually requires.
What Is an Essay Simplifier?
Many students overwrite their essays — using long words when short ones work, packing sentences with clauses, and hiding good ideas behind confusing prose. This hurts readability scores and grades.
Why Clear Writing Matters in College
Our essay simplifier uses AI to detect overly complex sentences and rewrite them clearly. It measures readability, breaks down long paragraphs, and suggests clearer alternatives — helping you communicate your ideas effectively.

What actually makes academic writing hard to read
Difficulty is rarely about long words. It comes from four structural habits, and each has a mechanical fix.
| Habit | What it looks like | The fix |
|---|---|---|
| Nominalisation | Verbs turned into nouns: "conducted an investigation of", "made a comparison between" | Put the verb back: "investigated", "compared" |
| Buried subject | The actor appears 20 words in, or not at all | Name who does what in the first eight words |
| Noun stacking | "student engagement measurement protocol design" | Unstack with prepositions: "the design of a protocol for measuring student engagement" |
| Passive by default | "It was found that…" when you found it | Use active where your field allows; keep passive where the method is the point |
The subject-verb test
Read the first eight words of any hard sentence. If you cannot find a concrete subject and a real verb in there, that is the problem — not the vocabulary.
Before and after, with the change named
The implementation of an intervention programme for the enhancement of reading comprehension was undertaken by the research team, with the measurement of outcomes being conducted at three separate intervals.
The research team ran a reading comprehension programme and measured outcomes at three intervals.
Three changes, none of which touch the meaning: implementation… was undertaken by became ran, the measurement of outcomes being conducted became measured outcomes, and the subject moved to the front. Nearly half the words were carrying grammar rather than content.
It is important to note that there exists a considerable body of evidence which would seem to suggest that a relationship may potentially exist between the two variables under consideration.
Substantial evidence suggests the two variables are related.
Here the hedging was doing the damage. Four separate softeners — would seem to, may, potentially, under consideration — stacked onto one claim until it said almost nothing. One hedge is academic caution; four is evasion, and markers read it that way.
When not to simplify
Simplifying is not the same as dumbing down, and some things must survive intact.
- Technical terms. "Significant" in statistics does not mean "large". "Theory" in science does not mean "guess". Replacing field vocabulary with everyday synonyms is an error, not a clarification.
- Necessary hedging. "Suggests" and "indicates" carry real meaning about the strength of evidence. Cut the stacked hedges, keep the honest one.
- Quotations. Anything inside quotation marks is fixed. Altering it is a citation error regardless of intent.
- Numbers and findings. "Declined by 23%" must not become "declined considerably".
- Required passive voice. Many methods sections expect it, because the procedure matters more than who performed it. Check your style guide.
How simple is simple enough
Readability scores are rough, but useful as a sanity check rather than a target to optimise.
| Writing | Typical reading grade | Average sentence |
|---|---|---|
| Undergraduate essay | 12–14 | 18–24 words |
| Journal article | 15–17 | 22–28 words |
| Thesis chapter | 14–16 | 20–26 words |
| Hard to follow | 18+ | 30+ words |
If your average sentence is over 30 words, something needs splitting. But a uniform 18 words everywhere reads as machine-generated — vary deliberately, as covered in our guide to AI-sounding prose.
