Analyze text structures, sentence lengths, and vocabulary trends locally. Detect AI writing (GPT-3, GPT-4, Claude, Gemini) with zero data leaving your device.
Our client-side tool provides an estimation of the probability that a text was generated by an artificial intelligence model. The analysis runs 100% locally in your browser to guarantee complete privacy and security for your documents.
The tool uses local heuristic rules, vocabulary variation metrics (burstiness), and structural syntax complexity (perplexity) tests to determine the likelihood of human vs AI authorship. No text is sent to third-party APIs or remote servers.
Yes. Highly structured academic writing, technical manuals, or heavily edited content can exhibit high predictability patterns similar to AI generation, leading to higher AI probability scores. Reading the highlight details is key.
For statistical reliability, a minimum of 25 words or 150 characters is required. Longer passages (200+ words) provide a more accurate evaluation.
