Turn a messy folder of images into a clean LoRA dataset, on your own PC. Sort by style, remove watermarks, text and social media UI, write captions with AI and rename everything, in one app.
Watermarks, logos, captions, social media buttons, emojis and QR codes are found and painted out, and black bars are cropped off, so your LoRA doesn't learn them.

BeforeAfterDrop in thousands of mixed images and get them grouped by visual style: photos, anime, 3D, painting, papercraft… Name the groups, fix the odd one out and export each style to its own folder.
For each kind of mark you choose: remove it, skip the image, or keep it. Text on clothes and tattoos can be left alone. Every run ends with a before/after report.
Writes a .txt caption next to every image with JoyCaption, a vision model that runs on your graphics card. Captions never mention the logos or watermarks you are about to remove.
Number a whole folder in one go: 000001.jpg, sexy000001.png… Images and their captions keep
the same number. See the result before you apply it, and undo it if you change your mind.

Secure checkout with Stripe. Windows 10/11 64-bit. An NVIDIA card is optional but much faster.
Sort by style, Clean images and Rename files also run on the processor, just slower. Captions really needs an NVIDIA card: without one it takes minutes per image and about 20 GB of RAM.
