AI Content Detector
Check if content was written by a human or generated by AI models like ChatGPT, Claude, or Jasper.
Analyze text to see the score.
How Detection Works
Large Language Models (LLMs) like ChatGPT are essentially "next-word prediction machines." Because they are trained to be statistically probable, their output often lacks the chaotic variance of human thought.
Perplexity
This measures how "surprised" a model is by the text.AI text has Low Perplexity because it chooses the most likely words. Human text is more random and complex (High Perplexity).
Burstiness
This measures the variation in sentence structure. Humans naturally mix short, punchy sentences with long, complex ones.AI text is monotonous and steady.
Analyzing the Difference
Common AI Traits
Repetitive sentence starts ("Additionally," "Furthermore"), lack of personal opinion, perfect grammar but boring flow, refusal to take a strong stance.
Common Human Traits
Typos or slang, metaphors, emotional language, sudden topic shifts, very short sentences mixed with very long ones.
Disclaimer
No detector is perfect.
Universities and employers should use these tools as a "signal," not a verdict. False positives often occur with non-native English speakers or highly formal technical writing.
