Caption-Anything is a versatile image processing tool that combines the capabilities of Segment Anything, Visual Captioning, and ChatGPT. Our solution generates descriptive captions for any object within an image, offering a range of language styles to accommodate diverse user preferences. It supports visual controls (mouse click) and language controls (length, sentiment, factuality, and language).

• Visual controls and language controls for text generation
• Chat about selected object for detailed understanding
• Interactive demo

• 2023/04/30: support caption everything in a paragraph
• 2023/04/25: We are delighted to introduce Track-Anything, an inventive project from our lab that offers a versatile and user-friendly solution for video object tracking and segmentation.
• 2023/04/23: support langchain + VQA, better chatbox performance
• 2023/04/20: add mouse trajectory as visual control (beta)
• 2023/04/13: add Colab Tutorial
• 2023/04/11: Release code

Explore the interactive demo of Caption-Anything, which showcases its powerful capabilities in generating captions for various objects within an image. The demo allows users to control visual aspects by clicking on objects, as well as to adjust textual properties such as length, sentiment, factuality, and language.
