Alt Text Generator

Drop an image, get a sensible alt attribute written for it. The AI describes what's in the image — subject, action, setting — in the concise style screen readers handle well. Output is ready to paste into your HTML, CMS, or accessibility audit fix list.

Why alt text matters

Alt text serves two audiences: screen-reader users (it's read aloud when a sighted user would see the image) and search engines (Google ranks images partly by their alt). Missing or generic alt ("image", "photo", "1234.jpg") fails both. WCAG 2.1 Level A (the baseline accessibility standard) requires meaningful alt for every non-decorative image.

Hand-writing alt for hundreds of images is brutal. AI generation gets you 90% of the way, with the writer reviewing and tweaking the output rather than starting blank.

What a good alt text looks like

1. Concise. 8–15 words. Screen readers don't pause for paragraphs.
2. Subject first. "A red Labrador puppy" not "An image showing a red Labrador puppy".
3. Includes context that matters. Setting, action, mood — only when it adds meaning.
4. No "image of" or "picture of". The screen reader already announces it as an image.

Bulk generation

Premium accounts can paste a sitemap URL or upload a folder. We crawl/process each image and return a CSV of {image_url, generated_alt} pairs ready for your CMS bulk-update tool.

Verify against the page context

The AI describes what it sees, but the right alt depends on the surrounding context. A photo of a dog might warrant "Labrador playing fetch" on a pet-toy page but "Henry, our office mascot" on an about-us page. Always treat AI-generated alt as a draft.
