How to use the AI Content Detector

  1. Paste a text sample in English, Russian or Ukrainian. Use at least 120 words for a useful result.
  2. Choose language manually or leave Auto detection enabled.
  3. Review the AI-like risk score, but do not treat it as proof of authorship.
  4. Open the paragraph heatmap to find the exact sections that look too generic, repetitive or uniform.
  5. Use the rewrite brief to add evidence, examples, numbers, named entities and first-hand editorial value.

What this detector checks

The tool measures structural and editorial signals that often appear in mass-generated text: low sentence burstiness, uniform paragraph length, low lexical diversity, repeated n-grams, generic AI-style phrases, formulaic transitions, weak specificity and high filler ratio.

It also separates three different things that many detectors mix together: AI-like risk, SEO-template risk, and evidence strength. A detailed ecommerce page can have strong evidence and still look templated; a legal service page can look polished but weak because it has almost no verifiable specifics.

Frequently Asked Questions

Can an AI detector prove that a text was written by AI?
No. No detector can prove authorship with certainty. This tool reports AI-like risk signals and explains what to review before publishing.
Which languages are supported?
English, Russian and Ukrainian. The detector uses separate phrase lists, stopword baselines and language detection for these three languages.
Does the tool use paid APIs?
No. The core detector is free and rule-based. It runs on transparent signals rather than paid black-box AI detection APIs.
How should I use the result for SEO?
Use it as an editorial quality check. If a paragraph has high risk, add first-hand examples, concrete facts, named entities, comparisons, data or sharper expert judgment.
