Nobody has claimed this yet. Be first.

The idea

Small online shops often leave product images without alt text, which hurts screen reader users and search. This tool reads a batch of product photos with their titles and drafts short, accurate descriptions the owner can review and copy.

Who it is for
Owners of small online shops selling handmade or vintage items
How it makes money
Pay per batch or small monthly plan
Suggested stack
Next.js, MySQL, Tailwind, hosted on a small VPS

PROMPT 2 OF 3

Send each photo and title to a vision capable AI model and ask for alt text under 125 characters that describes what is visible without marketing words. Show results in a table with the image, title, draft text and an edit box.
