AI Detector PRO
Sentence-level breakdown: which parts of the text look AI-written, color highlighting, a 12-metric radar chart and a statistical text profile. For a quick overall score use the regular AI detector.
Key facts
AI Detector PRO by sentence: paste a text and each sentence is highlighted from green to red by AI probability, with an overall score and a 12-metric radar on top. Completely free. The score is statistical, not proof: detectors err in both directions.
- Price
- Free
- Sign-up
- Not required
- Processing
- On our server: the TextHumanize library computes 12 statistical metrics, with no neural network and no text sent to external services; sentences are scored in a window of five neighbours
- Input
- Text from 50 to 50,000 characters (8–10+ sentences are better for the breakdown) or a page URL; one of 9 languages or auto-detect
- Limits
- 15 checks per minute per IP, no sign-up and no daily limit; “PRO” in the name is a free mode, no paid subscription is needed
- Output
- The AI probability in percent and a verdict, the text with colour-highlighted sentences, a score per sentence, a 12-metric radar and a statistical text profile

AI Detector PRO: which sentences look AI-written
The PRO detector is for a detailed breakdown: each sentence is scored together with its neighbours and colour-highlighted, the 12 metrics are plotted on a radar chart, and a statistical profile of the text sits alongside. Same 12 statistical metrics as the regular AI detector, no neural network. Need just an overall score? Use the regular AI detector.
How to Use

FAQ
Who it is for and typical uses
- Targeted editing. The highlighting shows which sentences look most like AI, and you can rewrite them or run them through the humanizer.
- Editors and reviewers. You see not just the overall percentage but the distribution across the text.
- Style analysis. The 12-metric radar and text profile show what drove the score (repetition, stock phrasing, evenness of sentences).
Honest limitations
- “PRO” is not a paid plan. The mode is free; the name means the extended breakdown.
- A sentence is scored in a window of five. A lone sentence is too short for statistics, so its score takes neighbours into account and is smoothed; a reliable breakdown needs 8–10 or more sentences.
- No neural network. We compute 12 statistical signals rather than compare against a model. A formal human text can light up red and an edited AI text can stay green.
- Not proof. The result must not be used to accuse a person of using AI.
- Languages. Nine languages; for others the estimate is less reliable.

Scroll the table sideways
Where we are weaker: a statistical method without training on AI texts, a sentence score blurred by its neighbour window, and no API or bulk checking.
When to choose PromoPilot: When you want to see which paragraphs of a text look “machine-made” and rewrite only those. For proving authorship or academic decisions no detector is enough.
