About
Overview
NSFW Checker is an AI tool for image content safety detection, mainly used to determine whether an image contains NSFW (not suitable for public display) or other inappropriate content. It is built on open-source models and machine learning capabilities, and has been adapted from Stable Diffusion's safety checker, allowing it to be used not only for AI-generated images but also for broader ordinary image detection scenarios.
Users can upload or drag and drop images directly through the webpage for inspection. It currently supports PNG and JPG formats, with a size limit of 50MB per image. The overall barrier to use is relatively low, making it suitable for basic screening before content publishing, asset organization, and community moderation.
