How to Detect Claude Content
Claude output tends toward longer, more nuanced sentences with higher vocabulary diversity. Often includes hedging language.
EyeSift uses multiple statistical signals to identify AI-generated content, including perplexity analysis, burstiness measurement, vocabulary diversity scoring, and sentence structure variance. While no detector is 100% accurate, our approach provides transparent probability scores that indicate the likelihood of AI generation.
Step-by-Step Detection
- Go to our free text detector
- Paste or upload the text content you want to verify
- Click "Analyze" to run the detection
- Review the AI probability score and supporting metrics
- Use the detailed breakdown to understand the analysis
Detection Accuracy for Claude
Detection accuracy varies based on several factors. Unmodified Claude output is generally detectable with higher confidence. However, accuracy decreases when content is:
- Manually edited or paraphrased after generation
- Mixed with human-written content
- Very short (under 200 words for text)
- Generated with specific prompts designed to evade detection
We always recommend using AI detection as one part of a broader verification process, not as the sole basis for decisions.
Frequently Asked Questions
Can EyeSift definitely tell if something was made with Claude?
No detector can definitively identify the specific AI tool used. EyeSift provides a probability score indicating how likely content is AI-generated overall. The statistical patterns we analyze are common across multiple AI models, though some model-specific characteristics can influence the analysis.
Is the detection free?
Yes, EyeSift's AI detection tools are completely free. No account or credit card required. Your content is processed locally in your browser for maximum privacy.
