Bulk AI Product Descriptions for Shopify
Lumi is a Shopify product description generator built for merchants who need on-brand product descriptions, SEO titles, meta descriptions, and WCAG-aligned alt text across the catalog without writing every SKU by hand.
Lumi learns your brand voice, uses product context to draft accurate content, and lets you review everything before publishing from Shopify admin.
Free plan available. Review before publishing.
Your product pages are costing you search traffic and sales
Every missing description, weak meta title, blank alt tag, and generic product blurb makes your catalog harder to find and harder to buy from.
For Shopify merchants with hundreds or thousands of SKUs, manual product copy turns into a backlog that slows launches, weakens SEO coverage, and creates cleanup work across the entire store.
- Product descriptions get rushed, copied, or skipped.
- SEO titles and meta descriptions stay inconsistent.
- Product images go live without useful alt text.
- New launches slow down while teams wait on copy.
- Generic AI drafts sound off-brand and still need heavy editing.
Generate descriptions, metadata, and alt text together
Lumi is built for Shopify catalog teams that need more than a one-off AI writer. It helps you create, review, and maintain the content that powers product pages, search visibility, image discovery, and accessibility support.
Product descriptions
Create benefit-led, on-brand descriptions that explain what the product is, why it matters, and who it is for.
SEO titles and meta descriptions
Draft keyword-aware metadata that helps search engines and shoppers understand each product page.
WCAG-aligned alt text
Generate descriptive product image alt text that supports accessibility and image SEO.
Catalog cleanup
Find content gaps across your Shopify catalog and prioritize the products that need attention first.
From messy catalog to publishable product copy
1. Connect your Shopify store
Install Lumi from the Shopify App Store and connect your catalog. No code or theme changes required.
2. Select products to update
Choose individual products, collections, tags, or bulk groups. Start small or process high-SKU batches as your plan allows.
3. Generate content in your brand voice
Lumi analyzes your existing product content and uses your catalog context to draft descriptions, SEO metadata, and alt text that fit your store.
4. Review, edit, and approve
Preview generated content before publishing. Edit individual drafts, approve in bulk, or use auto-apply options on eligible plans.
5. Keep new products from creating new backlog
Use ongoing catalog workflows to refresh new products, seasonal launches, and legacy content before gaps pile up again.
Product descriptions that sound like your store, not a generic prompt
Generic AI product copy is easy to spot. It overuses vague claims, repeats the same phrasing, and ignores the voice your customers already recognize. Lumi studies your existing descriptions, tone, vocabulary, and structure so new product copy feels consistent across your catalog.
Before: generic AI copy
"This premium product is made with high-quality materials and exceptional craftsmanship. Perfect for everyday use, it combines style and functionality."
Problems:
- Sounds interchangeable
- Adds little product-specific value
- Uses filler language
- Does not reinforce brand identity
After: Lumi brand voice AI
"Designed for everyday wear without the throwaway feel, this piece pairs durable materials with a clean silhouette that works across seasons. Dress it up, keep it casual, and let the details do the work."
Why it works:
- More specific
- More natural
- More benefit-led
- Easier to adapt by category, audience, and tone
Stop writing product descriptions one SKU at a time
Manual writing does not scale when your catalog keeps growing. Lumi helps ecommerce teams move from copy-paste cleanup to repeatable content operations.
Use bulk workflows to:
- Refresh legacy product descriptions
- Launch new collections faster
- Generate SEO titles and meta descriptions
- Improve product image alt text
- Standardize tone across categories
- Reduce repetitive copywriting work

Give every product page a better chance to rank
Search engines need clear, descriptive product content. Shoppers need copy that explains benefits, use cases, materials, fit, compatibility, and differentiators. Lumi helps you build consistent SEO coverage across your Shopify catalog.
Natural keyword integration
Add relevant product terms without keyword stuffing or robotic phrasing.
Long-tail product targeting
Create descriptions that support specific buyer searches, not just broad category terms.
Metadata automation
Generate SEO titles and meta descriptions alongside product descriptions so every page has stronger search context.
Image discovery support
Pair product copy with descriptive image alt text to support Google Images, visual search, and accessibility workflows.
Product copy and accessibility support in one catalog workflow
Lumi is not just an AI writing tool. It helps improve the underlying product content fields that shoppers, search engines, screen readers, and ecommerce teams depend on.
Use Lumi to improve accessibility support with WCAG-aligned product image alt text, stronger metadata coverage, review-before-publish controls, and higher-tier workflows that keep remediation records for ongoing good-faith documentation.
- Find missing or weak product content
- Generate WCAG-aligned image alt text
- Improve SEO metadata coverage
- Review before publishing
- Keep exportable remediation records on higher-tier workflows
- Support ongoing accessibility documentation
Lumi supports remediation work, but it does not promise guaranteed compliance because accessibility obligations extend beyond product descriptions and image alt text.

A better workflow than manual writing or generic AI
| Approach | What happens | Limitation |
|---|---|---|
| Manual writing | A person writes each product description, SEO title, meta description, and alt tag. | Accurate, but slow and expensive at catalog scale. |
| Generic AI prompts | You paste product details into a chatbot and edit the output. | Fast, but disconnected from Shopify, brand voice, product images, and bulk publishing. |
| Lumi | Generate on-brand descriptions, SEO metadata, and WCAG-aligned alt text inside a Shopify catalog workflow. | Built for review, bulk cleanup, and ongoing catalog maintenance. |
Merchants use Lumi to clear content backlogs faster
Early Shopify reviews point to two consistent themes: fast cleanup of missing alt text and stronger brand voice output. Review feedback calls out the Brand Voice Analyzer as a standout capability while also highlighting how quickly missing alt text gaps can be addressed.
Fast backlog cleanup
Fix missing content fields across many products without manual copy-paste work.
Better brand consistency
Generate product copy that follows your existing tone instead of sounding like default AI.
One Shopify workflow
Create descriptions, metadata, and alt text from the same catalog cleanup process.
