Pinterest introduced a system in April 2025 to automatically detect when an image has been created or significantly altered by AI tools, and labels those images visibly for users browsing the platform. In October 2025, Pinterest added user controls allowing people to reduce how much AI-generated content appears in specific categories of their feed — including beauty, art, fashion, and home décor. The company estimates that approximately 57% of all internet content contains some degree of AI modification.

Details

The detection system analyzes metadata using the IPTC Photo Metadata Standard (an industry format that can record whether an image was AI-generated) as well as machine learning classifiers that examine pixel-level characteristics — such as noise patterns and color distribution — to identify signs of AI generation. Detected content receives an "AI modified" label visible on the Pin. The company has acknowledged the system produces false positives: artists have reported that hand-drawn work was incorrectly flagged, with some accounts receiving automated bans as a result. The 404 Media outlet documented multiple such cases. Pinterest's user filtering controls, launched October 2025, let users reduce (but not entirely eliminate) AI-generated content from specific feed categories.

Other practices by Pinterest

OtherPinterest maintains an internal program called Responsible AI that covers three areas: building inclusive AI features (the skin tone, body type, and hair pattern tools described in Practice 21), testing its AI systems for unfair bias (using internal tools that measure whether models perform equally well across different groups of users), and developing guidelines for the safe use of generative AI. The program includes red teaming — structured attempts to find flaws or harmful outputs in AI systems before they launch.OtherPinterest is testing AI-powered upgrades to its Boards feature that go beyond simple user-organized collections. In October 2025, Pinterest launched an experiment in the U.S. and Canada where the platform automatically generates outfit ideas from a user's saved fashion Pins ("Styled for you"), creates entirely AI-curated boards based on trending styles ("Boards made for you"), and suggests related products based on what a user has already saved ("Make It Yours").OtherPinterest uses AI to identify diverse skin tones, body types, and hair patterns across billions of images on its platform, then uses those signals to ensure that search results and recommendations reflect a broader range of human appearances. Users can filter fashion search results by body type ranges, skin tone ranges, and hair patterns. The body type technology launched in September 2023, with public user filters rolling out in March 2024; skin tone ranges have been available since 2018.
