Overview

• Nightshade, a tool developed by the University of Chicago, allows artists to 'poison' their images to deter AI models from using them without permission.
• The tool makes subtle pixel-level changes to images that are invisible to the human eye but can drastically alter how an AI model interprets the image.
• Nightshade is designed to protect artists' intellectual property and discourage AI model trainers from disregarding copyright notices and do-not-scrape directives.
• The tool has been released for Windows PC and Apple Silicon Macs, and is available for artists to download and use on their artworks.
• Nightshade is the second tool from the University of Chicago team, following Glaze, a program designed to alter digital artwork to confuse AI training algorithms.
