Who uses this tool
The same file, different jobs. Tap a prompt to try it.
E-COMMERCE
A whole catalog, described
Zip your product photos and get alt text that names the item, color, and angle — not “a shoe”.
PUBLISHING & BLOGS
Every article image covered
Hero images, inline photos, and charts described for readers, with decorative dividers flagged.
EDUCATION
Accessible course materials
Upload the slide deck PDF; diagrams and charts get long descriptions students can actually learn from.
GOVERNMENT & COMPLIANCE
WCAG and Section 508 audits
Batch a site's media folder and close every missing-alt finding with a CSV your devs can apply.
SOFTWARE & DOCS
Screenshots that make sense
Docs screenshots get alt text naming the screen and state, with UI text included verbatim.
MARKETING
Email and social, accessible
Campaign graphics described by their message, with important on-image text carried into the alt.
SECURITY
Built for sensitive documents
Bank statements, medical files, case records. Security isn't a feature we added — it's the foundation.

Questions
Auto-captions describe pixels (“a person at a desk”). Alt text describes purpose. Tell this tool the page and audience, and it writes what the image means there — with charts, diagrams, and screenshots getting a long description that carries the actual data and text.
Images that carry no information for a reader — spacers, borders, aesthetic flourishes — should get an empty alt attribute (alt="") so screen readers skip them. The tool flags these instead of inventing filler descriptions for them.
1 credit per image, minimum 10 credits per job. A 200-image product catalog is 200 credits. Loose images, zips, and PDFs of slides all count per image or page inside.
