ComfyUI-SAM3

Why we included this project

Meta's SAM3 segmentation model runs inside ComfyUI through this node pack, so you can isolate objects in stills or video by typing a short phrase like "person" or "car" instead of tracing masks by hand. The nodes return segmentation masks and bounding boxes, which covers background removal, inpainting prep, and isolating a subject before further generation steps. When text alone is too coarse, an interactive points editor adapted from KJNodes lets you click on the image to refine the result. It installs as a custom node through ComfyUI Manager or a manual clone, so it behaves like a normal part of your existing ComfyUI setup rather than a separate tool to learn.
