How AI describes Quick and Simple Labeler (QSL)

QSL (Quick + Simple Labeler) is an open-source Python library for labeling images, videos, and more, usable from Jupyter/Colab or via a CLI web server with the same interface. It supports labeling small to large datasets with features like keyboard shortcuts, zoom/pan, and advanced region tools (flood fill for segmentation and polygon snapping), and can target files on disk, the web, S3, or in-memory arrays while displaying metadata. Label configurations can be defined programmatically or in the UI, labels can be saved to JSON, and it supports batch labeling and notebook workflows for quick analyses or model inferences.
