About Claude AI Detector
The Claude Detector is a focused, state-of-the-art tool designed to identify whether a piece of text was written by a human or generated by Claude. It combines machine-learning classifiers with statistical analysis of linguistic patterns to deliver highly reliable verdicts.
It supports the full range of content types Claude is commonly used for — blog posts, essays, marketing copy, product descriptions, social posts, emails and more — and works equally well on short snippets and long-form articles.
Accuracy regularly exceeds 98% on the latest Claude releases, with continuous updates as new versions ship. Where high-stakes decisions are involved, we recommend pairing the detector with a quick human review for absolute confidence.
Beyond a yes/no verdict, the tool surfaces sentence-level probability scores, key linguistic indicators, and clear recommendations to help you decide what to publish, edit or reject.
How It Works
Detection runs in three stages: tokenization and embedding generation, multi-model statistical analysis tuned to Claude, and a final ensemble classifier scored against millions of labeled samples.
Each submission is evaluated for perplexity, burstiness, syntactic regularity, lexical diversity and stylometric fingerprints that correlate with known Claude output distributions.
Results return in seconds with a confidence score, sentence-level breakdown, and a clear verdict you can act on immediately.
Supported AI Models
The Claude Detector is fine-tuned specifically on the Claude fingerprint, but our broader platform supports detection across OpenAI’s GPT family, Anthropic Claude, Google Gemini, Meta Llama, xAI Grok, DeepSeek and most major open-source models.
Model coverage is updated continuously as new versions are released, so detection accuracy keeps pace with frontier model improvements.
For each supported model we maintain a dedicated, specialized classifier never a single generic detector stretched thin across many models.
