Turn Images into Words with AI

What is CaptionBot?

CaptionBot is an AI-powered image captioning tool developed by Microsoft that uses computer vision and natural language processing to describe the content of images in human-readable language. It was designed to demonstrate how AI can interpret visual data and generate accurate, concise, and natural-sounding captions.

Though relatively lightweight compared to newer models, CaptionBot plays a vital role in accessibility, automated tagging, and understanding visual content—especially for early-stage or simple applications.
