iStock uses an automated prompt-blocking system within its Generative AI tool to prevent users from generating images of recognizable people, trademarked logos, copyrighted characters, or other legally risky content. The system also enforces a policy against generating photo-realistic depictions of people who are not real.
Details
iStock's FAQ states that the platform has 'taken care to block prompts that could generate problematic content.' The underlying AI model (powered by Bria) was trained exclusively on licensed data and engineered to prevent outputs that include known brands, trademarked products, public figures, or other copyrighted elements. Additionally, iStock's contributor policy explicitly prohibits photo-realistic AI-generated depictions of people in uploaded content. The prompt-blocking system operates automatically at the point of generation on the iStock AI Generator console.

Other practices by iStock
ModerationiStock uses a policy — enforced through contributor guidelines and file inspection — to exclude externally AI-generated images from its licensable stock library, while permitting contributors to use AI tools for minor retouching only. The contributor guidelines explicitly bar files created with generative AI tools such as Stable Diffusion, DALL-E, Midjourney, or Adobe Firefly.RecommendationiStock offers a reverse image and video search feature that uses AI image recognition to let users upload a reference photo or video clip and find visually similar stock content from iStock's library, without needing to type keywords.RecommendationiStock deployed Enhanced Search, an AI-powered search feature, in March 2024, allowing customers to find stock images, videos, and illustrations using natural, conversational language rather than exact keyword matches. Enhanced Search is turned on by default for all creative searches on istockphoto.com.
