AI content detector - honest by design
See the writing-style signals in your text as plain bands - never a made-up "82% AI" score. AI detection is unreliable, and we show you exactly why instead of pretending otherwise.
Analysis runs locally in one pass - your text is not stored. This tool does no web search; for copied text use the plagiarism checker.
Read this first: AI-writing detection is not reliable, and this tool does not pretend otherwise. It reports stylometric signals - patterns common in generated text - not proof. False positives are common: careful, formal, edited, or non-native writing often trips these signals, and a determined author can evade them. Never use this as sole grounds for an accusation.
What the signals mean
Stylometry, not magic
We measure well-understood traits - how much sentence length varies, model-favored phrasing, repeated openers - that tend to differ between human and generated prose.
Bands, never fake percentages
There is no honest way to turn writing style into a calibrated probability. So we show a coarse band and the individual signals, and let you judge - not an invented number.
False positives are common
Formal, edited, technical, or non-native writing often looks "AI-like" to any detector. Never treat a band as proof or grounds for an accusation.
