Label Studio

Active

Label Studio is an open-source data labeling platform for text, images, audio, and video. Connect it to queue work for human annotators, read back completed labels as ground truth, and close the loop between an agent's output and a human's correction. Works against Label Studio Cloud or a self-hosted instance.
