Most detectors are a black box. We show ours.
Detectors do not just say yes or no. They flag measurable patterns. We surface the same four, so you can see exactly why a draft reads machine-made, whether it is yours or someone else's.
Burstiness
Humans vary sentence length without thinking. Models flatten it. Detectors weight this signal hardest.
Rhythm
Runs of same-length sentences read machine-made. We flag every one and show you where.
Vocabulary
Delve, seamless, robust, a testament to. The stock words that scream generative AI.
Punctuation
Em-dash pileups and stacked rule-of-three lists are among the loudest tells.
Questions
How does the AI detector work?+
Paste or upload any text and it is scanned sentence by sentence for the patterns AI writing leaves behind: flattened sentence rhythm, stock vocabulary, and predictable structure. You get a 0 to 100 score plus the reasoning behind every flagged line.
How accurate is the AI detection score?+
No detector, ours included, is 100 percent certain on every input. Treat the score as a strong signal to investigate further, not a verdict on its own, especially on shorter drafts.
What should I use this for?+
Checking any draft you are not sure about before it goes out: marketing copy, LinkedIn posts, newsletters, reports, and other professional writing. Not built for catching homework.
What happens if I go over my word limit?+
The free check on this page caps out at 300 words per scan with a limited number of free scans per day. Sign up for a higher monthly word allowance and the full sentence-by-sentence report.
