The Alt Text GPT is a dedicated tool that enables users to generate SEO-optimized alternative text (alt text) for images. Operating on top of ChatGPT, it is specifically designed to inquire the context of the images provided to deliver tailored alt text. Alt text is of crucial importance in terms of web accessibility as it provides descriptive information for people who, due to various reasons, cannot see the images on the web page. It also helps in improving the SEO performance of the web page.The principal function of Alt Text GPT is to generate alternative text that clearly describes the content and function of an image, tailoring the result based on the context provided by the user. Upon receiving an image, the system interacts with the user by asking questions such as 'What's the image's context?', 'Title of the related content?', 'Use of this image?', and 'What's the image's intended message?'. This information is then utilized to generate the most appropriate SEO-optimized alt text. It requires a subscription to the ChatGPT Plus service for use. This GPT is well-suited for individuals or businesses who need to quickly generate accurate, context-aware alt text for web content, aiding accessibility and enhancing SEO.
