How Botfilter runs on your device

Limits

  • Detection is probabilistic. Each mark shows a probability, such as “likely AI-written · 92%”, not a verdict.
  • Texts under 25 words are skipped, because there is too little to judge.
  • Human writing can be flagged, most often work email and older web pages in our tests.
  • Use it to filter what you read, not as proof about the person who wrote it.
