Detailed Introduction to Alt Text Assistant

Alt Text Assistant is a specialized tool designed to generate alternative text (alt text) for images. Its primary goal is to support accessibility by providing text descriptions for visuals, aiding people who rely on screen readers, such as individuals who are blind or have low vision. The assistant helps create concise and relevant alt text, guiding users to describe images in ways that are useful and informative for those unable to see them. It also focuses on more complex images like charts or graphs, offering detailed descriptions while maintaining context sensitivity. For instance, a photo of a beach would result in a brief description of the scene, while a detailed chart with data points would receive a more structured explanation of the trends and figures involved. Importantly, Alt Text Assistant always encourages human review, as context and nuanced understanding are critical for making alt text truly effective.
