Cara, a new AI-skeptical artist portfolio app, has surged to hundreds of thousands of users. It provides a platform for artists to share their work while preventing AI-generated content. Developed by photographer Jingna Zhang and a small team, Cara integrates Glaze, a tool from the University of Chicago's SAND Lab, to protect original art from being used in AI training. Over the weekend, the app's user base skyrocketed to over 300,000, propelling it into the Top 5 in Apple's U.S. App Store, despite growing pains in scaling its servers.
