AI Content Detector

AI-generated text tends to pick the statistically most predictable next word more often than a person naturally does, and it tends to keep sentence length and complexity more even throughout a passage, two measurable patterns, sometimes called perplexity and burstiness, that a detector actually looks for rather than anything about whether the writing itself is good or bad. This tool analyzes a piece of text for those patterns and estimates how likely it is to have been generated by a model like ChatGPT, Claude, or Gemini rather than written by a person. Useful for screening a submitted piece of writing before publishing it under a human byline, checking whether a suspicious review or comment shows the statistical fingerprint of generated text, or spot-checking a document before accepting it as originally written.
