Every meaningful image needs alt text — but writing it by hand doesn’t scale. This tool uses AI vision to look at each image and write a clear, specific description in seconds. That single line of text does triple duty: it lets screen readers describe the image to visually impaired users (a WCAG/ADA requirement), it helps Google understand and rank your images, and it makes you visible to AI answer engines like ChatGPT and Perplexity, which read alt text because they can’t interpret raw pixels.
What good alt text looks like
- Specific: “Golden retriever puppy chewing a blue rope toy on grass,” not “dog.”
- Concise: under ~125 characters — one natural sentence.
- No filler: skip “image of / picture of” — screen readers already say it’s an image.
- Contextual: reflect the page’s topic and, where truthful, your target keywords.
