AI Text Detector
Detect if text was written by AI or a human
What is AI Text Detector?
AI Text Detector analyzes text to determine the likelihood that it was generated by an AI language model (such as GPT, Claude, or Gemini) rather than written by a human.
When to use this tool
- Checking if student submissions are AI-written
- Verifying authenticity of published content
- Reviewing AI-generated drafts for manual refinement
- Educating users on AI text characteristics
How it works
Evaluates text for statistical patterns typical of AI-generated content, including burstiness (variation in sentence length), perplexity (predictability of word choices), repetition patterns, and vocabulary distribution. Produces a probability score indicating the likelihood of AI authorship.
