Can this tool tell if AI wrote my text?
No, and no other tool can do it reliably either. Free “AI detectors” that show a percentage such as “87% AI” are guessing from the same few signals this page shows openly: how much sentence length varies, how often words repeat and how readable the text is. Careful human writers often score as “AI”, and lightly edited AI text often scores as “human”. Studies of commercial detectors have found high false-positive rates, especially for people writing in a second language. OpenAI withdrew its own AI classifier in 2023 because of low accuracy.
So instead of a verdict, this Writing Style Analyzer gives you the measurements themselves and practical suggestions for improving the text. Use it to edit your own writing, or as one piece of context when reviewing someone else’s work, never as proof.
What each number means
- Average words per sentence: 15–20 is comfortable for most readers. Above 25 starts to feel heavy.
- Sentence variety: based on how much sentence lengths differ from the average (coefficient of variation). Writing where every sentence is about the same length reads as monotonous. Some people call this “burstiness”.
- Reading ease: the Flesch Reading Ease score, from 0 (very hard) to 100 (very easy). 60–70 is plain English.
- Grade level: the Flesch–Kincaid grade, roughly the US school year needed to read the text easily.
- Vocabulary variety: the share of different words in each 50-word stretch, averaged across the text. Higher means fewer repeated words.
How to use the report
- Look at the sentence-length chart. A flat row of similar bars means the rhythm needs variety.
- Check the most repeated words and replace or remove the ones that are not key terms.
- Rewrite the longest sentences, usually by splitting them in two.
The formulas are designed for English. Results for other languages are approximate. For repeated sentences, try the Duplicate Sentence Finder.
