Frequently asked questions

What is a good average sentence length for fiction?

Commercial fiction often averages 12–18 words per sentence, but variety matters more than the average alone.

What does monotony percentage mean?

It measures how many adjacent sentence pairs have similar word counts. High monotony suggests repetitive rhythm.

Can I use this on AI-generated text?

Yes. AI drafts often produce uniform sentence lengths — this tool spots that pattern quickly.
