Claude AI detector
Anthropic's Claude models (including Claude 3.5 Sonnet and Opus) are celebrated for their natural, nuanced prose, which can make them harder to spot than earlier assistants. This tool inspects the subtle stylometric markers and conversational cadences that Claude models consistently exhibit.
Claude tends to write with balanced, considerate perspectives, structured parallel clauses, and distinctive transitions (such as 'It is worth noting', 'In essence', 'From this perspective'). Our classifier scores these patterns alongside token entropy.

Frequently asked questions
Is Claude 3.5 Sonnet harder to detect than ChatGPT?
Generally yes, because Claude's training emphasizes conversational flow and nuanced syntax. However, its signature hedging, balanced transitions, and uniform paragraph structure remain statistically detectable.
Does it check both prose and analytical writing?
Yes. Claude's tendency to organize thoughts into neat hierarchical lists or balanced pros/cons is a primary signal assessed by our pipeline.
Can Claude detector results be used for school or university submissions?
We advise caution. Detectors provide an indicative assessment, not conclusive legal evidence. Never penalize a student based solely on automated classifier scores.
