About Winston AI

Winston AI detects AI text and images, including deepfakes, and reports a 99.87% accuracy figure from its own testing of 12,000 English documents. Handwriting and scanned documents go through OCR, and results export as PDF reports. The Advanced plan adds HUMN-1+ certification, which marks a site as human-written. Annual billing halves the price across every tier. Detection covers ChatGPT, Claude, Gemini and Llama for text, and Midjourney, DALL-E and Stable Diffusion for images.
