/ˌen-es-ˌdəb-əl-yü-ˈef/ • Not Safe For Work
NSFW stands for "Not Safe For Work" and is used to label content that would be inappropriate to view in a workplace or public setting. The term originated in internet forums and has become a standard content warning across digital platforms.
In content moderation, NSFW detection is one of the most common and important use cases, helping platforms filter adult or inappropriate content to protect users and maintain brand safety.
Accurate NSFW detection protects minors from adult content, maintains advertiser brand safety, ensures legal compliance, and creates appropriate user experiences based on platform guidelines.
Modern NSFW detection uses deep learning models trained on millions of labeled images. These AI systems analyze visual features to classify content into categories like safe, suggestive, or explicit. The best systems achieve over 99% accuracy with minimal false positives.
NSFW detection APIs typically return confidence scores indicating the probability that content is inappropriate. Platforms can set custom thresholds based on their policies - stricter thresholds for children's apps, more lenient for adult platforms.
