Description

Generate alt text and product SEO copy in bulk. Use Vision AI while supporting accessibility.

Missing alt text triggers lawsuits and tanks your image SEO. Lumi's Vision AI analyzes your actual product photos to write accurate, descriptive alt text—not guesses from filenames. Unlike overlay widgets that mask problems temporarily, Lumi permanently fixes your Shopify database. Google's crawler reads your store like a blind user does: proper alt text means better rankings and legal protection. Scan your catalog for gaps, bulk-fix thousands of images, and download audit trail reports.

Vision AI alt text that supports WCAG, ADA, and EAA accessibility
Bulk-generate product descriptions, titles, and meta tags from one place
Build a reusable brand voice profile so AI copy matches your tone
Review, edit, and approve content before publishing
Automate the creation of product content for new products and alt text images

Downloaded this primarily to patch up some SEO holes in our image library. It cleared the backlog of missing alt tags almost instantly. However, the standout feature for me is the Brand Voice Analyzer. It picked up on our specific brand tone immediately, so the descriptions it generates are spot on. It’s rare to find a tool that solves the technical stuff this quickly while nailing the creative side too.
