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 - em-dash habits, "not just X, but Y" phrasing, hedging, chat-assistant leftovers, sentence-length variation, model-favored vocabulary - 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.

    A clean result is not proof of anything either

    Newer models write less like the early-2020s stereotype, and light editing removes most of what any style test can see - changing a few dashes and adding contractions is often enough. So this tool can miss generated text, and "no strong AI signals" does not mean a person wrote it. We would rather tell you that than sell you a number.

    Frequently asked questions

    No AI detector is reliable, and we will not pretend this one is. It reports stylometric signals - patterns that are common in generated text, like unusually uniform sentence length - not proof. We show you the individual signals so you can judge them, and we show a band, never a fake precise percentage.

    Because that number would be invented. There is no honest way to turn writing style into a calibrated probability that a specific passage was AI-written. Tools that show a confident percentage are giving you false precision - the same reason our plagiarism checker never claims a made-up accuracy figure.

    Yes, and often. Careful, formal, or heavily-edited writing, technical documentation, and text by non-native English writers all tend to trip the same signals as generated text. Treat a "possibly AI" band as a prompt to look closer, never as an accusation.

    The plagiarism checker compares your text against the live web to find copied passages. This tool looks only at writing style to flag patterns common in AI output - it does no web search. They answer different questions; use both, and trust neither as sole proof.

    No. AI-signal analysis runs locally on our server in a single pass and the text is not saved to any report or database - it is only used to compute the signals shown back to you.
