How TextShift AI Detection Works

TextShift uses a fine-tuned RoBERTa-base model (125M parameters) trained on millions of human-written and AI-generated text samples. The model analyzes linguistic patterns, perplexity scores, and burstiness metrics to determine if text was written by a human or AI with 99.18% accuracy.

Unlike simple classifiers, TextShift's model understands nuanced differences between human and AI writing styles across multiple AI models including GPT-4, Claude 3.5, Gemini, and Llama.
