Short text, lower confidence
Short passages simply contain fewer clues. When you check less than 200 words, expect lower confidence and treat results as a rough indication.
No AI detector is 100% accurate. Results are probabilistic estimates and should never be used as the only evidence that someone used AI. Treat them as one signal alongside drafts, revision history, and a conversation with the writer.
What you can check
The text checker is suited to shorter, everyday pieces: emails and cover letters, product and app reviews, forum and discussion-board posts, short-answer homework, social captions and customer support replies. The minimum is 80 words; very short snippets do not contain enough signal for a meaningful estimate.
Reading results on short text
With fewer sentences, a single generic phrase has more weight, so results swing more easily. Focus on the reasons attached to each sentence rather than the headline percentage, and treat “mixed” results as a normal outcome for short pieces.
If you can, check a longer sample from the same author — several posts or emails combined — to get a steadier picture.
Common AI patterns in short text
Opening by repeating the question, polite but empty phrases (“I hope this message finds you well”), lists of exactly three benefits, enthusiastic but non-specific praise in reviews, and closing summaries that add nothing new. None of these prove AI use on their own — many people write this way — but together they raise the AI signal.
Frequently asked questions
Can it check reviews for authenticity?
It can flag AI-like phrasing in reviews, but it cannot verify who wrote them or whether they are genuine.
What is the minimum length?
80 words. Results become steadier from around 200 words.
Can it tell which AI wrote the text?
No. It looks for patterns common to large language models in general and does not identify a specific product or model.
Is it free?
Yes. No account, no sign-up and no paid tier.
