NSFW Checker

What is the NSFW Checker?

The NSFW Checker (“Is This Image Safe For Work?”) uses a safety checker originally included with Stable Diffusion. With a few changes, it can evaluate not only AI-generated images but also arbitrary images, helping you determine whether content is appropriate for a work environment.

How it works

Upload an image and the tool runs the underlying safety logic to flag potentially unsafe content. The safety checker is somewhat poorly documented, but the workflow is straightforward: you provide an image and get an assessment intended for SFW use.

Supported uploads

You can click to upload or drag and drop your file into the interface. Supported formats are PNG and JPG, with a maximum file size of 50MB.

Who it’s for

This is a practical option for anyone doing lightweight content moderation or screening images before sharing them in professional or secure settings. It’s especially useful when you need a quick check across both AI and non-AI images.

Pricing

No pricing or plan details are provided.
