Introduction

X-AnyLabeling is a lightweight, efficient, and unified cross-platform desktop application for AI-assisted annotation of text, image, video, and multimodal data. It combines versatile built-in tools, automated labeling workflows, state-of-the-art deep learning models, and flexible multi-format import and export. For remote inference, X-AnyLabeling-Server provides a lightweight, extensible backend for connecting custom models and compute resources.

Key Features

• Unified support for annotating and processing text, image, video, point cloud, and multimodal data.
• Covers tasks such as image classification, object detection, instance segmentation, pose estimation, oriented object detection, multi-object tracking, optical character recognition, lane annotation, image captioning, visual question answering, document parsing, and 3D point clouds.
• Provides polygons, rectangles, cuboids, rotated boxes, quadrilaterals, circles, lines, polylines, points, masks, and task-specific tools for text detection, text recognition, and KIE.
• Integrates a wide range of state-of-the-art deep learning models for AI-assisted annotation, automated labeling, and batch dataset prediction.
• Supports both local and remote inference through engines and serving frameworks such as ONNX Runtime, TensorRT, OpenCV DNN, vLLM, and SGLang.
• Supports importing and exporting formats such as COCO, VOC, YOLO, DOTA, MOT, MASK, PPOCR, MMGD, VLM-R1, and ShareGPT.
• Runs on Windows, Linux, and macOS, with interfaces available in English, Simplified Chinese, Japanese, and Korean.
• Supports custom model integration, flexible extension, and secondary development.
