Detector.

The detector analyzes linguistic patterns and statistical signals that are characteristic of AI-generated text from ChatGPT, Claude, Gemini, DeepSeek, and other large language models. It works on the text itself, not the source, so it applies regardless of which tool was used to write it.

The score is a heuristic estimate based on the text's structure, phrasing, and patterns. Accuracy depends on text length, topic, and writing style. For best results, use at least 100 words. Consider the result a directional signal and validate with multiple checks when it matters.

Different detectors use different heuristics, training data, and thresholds. There is no universal standard for AI detection. Results across tools will naturally vary, sometimes significantly. No single score is definitive.

In rare cases, yes. Highly structured, formal, or templated human writing can trigger patterns the detector associates with AI output. The score is an indicator, not proof of authorship.

Without signing up, you get 3 free checks per day. With a HumanTone account, your daily detection limit is significantly higher and included with every plan. If you also want to humanize your content and reduce the AI score, plans start with a free 1,000-word trial. No credit card required.

Below 30 words, the text is too short for the analysis to produce a reliable signal. Above 1,500 words, split your content and check each section separately for more precise results.

Yes. The detector supports 60+ languages and is designed to produce consistent results across all of them. Language, topic complexity, and writing style can all influence the score to some degree.
