AI Alt Text / Caption Generator

Alt text (alternative text) is a written description of an image used by screen readers for visually impaired users, by search engines for SEO, and as fallback text when images fail to load. Good alt text improves web accessibility (WCAG compliance), boosts image SEO rankings, and creates a better experience for all users.

The AI uses advanced vision models to analyze the content, context, and details of your image. It identifies objects, people, actions, text, colors, and composition, then generates a natural-language description tailored to your chosen output type, tone, and length.

Alt text focuses on accessibility — concise, factual descriptions of what's in the image. Social captions are engaging and conversational, often including emoji and hashtag suggestions. Product descriptions emphasize features, materials, and selling points for e-commerce listings.

Absolutely. Search engines cannot see images directly — they rely on alt text to understand image content. Well-written alt text helps your images appear in Google Image Search, improves page relevance for related queries, and contributes to overall page SEO. It is one of the easiest wins for image optimization.
