Shopify catalog cleanup
Lumi shows which products are missing descriptions, image alt text, SEO titles, or meta descriptions, then drafts the empty fields from your product details and photos. You compare, edit, and decide what gets published to Shopify.

A forest-green ceramic pitcher with a generous rounded handle and an easy-pour spout. A simple addition to the everyday table.
Ready for your review
Sound familiar?
Your supplier sent the photos, but not the words. Alt text gets skipped. Descriptions stay one line long. SEO titles and meta descriptions wait for a quieter week.
Soon hundreds of products need fixing, one at a time, so the cleanup keeps sliding to next month.
Lumi turns that backlog into batches you can finish: see what's missing, start with one small batch, approve the drafts you like, and publish to Shopify.
| Product | Description | Alt text | SEO title | Meta description |
|---|---|---|---|---|
| Forest Green Ceramic Pitcher | Filled | Empty | Empty | Empty |
| Speckled Stoneware Bowl | Filled | Empty | Filled | Empty |
| Linen Table Runner | Empty | Empty | Empty | Empty |
| Oak Serving Board | Filled | Filled | Empty | Empty |
What Lumi writes for you
Work on one product or a whole batch. All four are on every plan, including Free, within your credits.
Drafted from your product's own details. Lumi is instructed not to invent certifications or warranties.
Stop starting from a blank page.Your product title is for shoppers. Your SEO title (Shopify calls it the page title) is for search. Lumi writes the second without touching the first.
Your product title stays put.The short summary under your search listing. Lumi keeps drafts to 160 characters; Google may still shorten or rewrite them.
Give searchers a reason to click.Written from the actual photo, not copied from the product title. Works for product images and Shopify Files on every plan.
IMG_4471.jpg is not alt text.How it works
Five simple steps.
A lot less opening products one by one.
After install, Lumi counts the products missing descriptions, alt text, SEO titles, and meta descriptions. Free checks up to 500 Online Store products, best sellers first; paid plans and Cleanup check the full catalog. Filter by vendor or collection and sort by what's missing.
Pick products and fields. Lumi drafts descriptions from your product details and writes alt text from each actual photo. Cleanup and Maintain add your brand voice and 17 writing languages.
Your approval is the publish button. See current and proposed copy side by side. Edit any word, regenerate when your plan includes that option, or skip it. Nothing from a batch you start reaches your store until you publish.
Publish one update or a whole batch into the native Shopify fields your theme already shows. No spreadsheets, no copy and paste, no theme code.
Lumi saves what was there before it publishes, so you can restore the previous version of supported changes. Every plan can export published changes as a CSV, and paid plans can also export completed alt-text fixes as a CSV.
You're in charge
Batches you start wait for you, with current and proposed copy side by side. Check the facts, edit the wording, or toss it. Regenerate when your plan includes that option.
Filter by vendor, collection, or product type, sort by what's missing, and choose the fields. Lumi skips fields that already have content unless you choose to rewrite.
Lumi saves what was there before it publishes, so you can restore the previous version of eligible changes without overwriting a later edit.
Optional on Maintain
Keep up as your catalog grows. On Maintain, Lumi can draft the empty fields you choose when you add a product and fill in missing alt text after updates. It only fills empty fields and uses your monthly credits.
Automation is off until you turn it on. Once on, it starts set to publish automatically. Choose “save as drafts” to review each new batch first.
Why Lumi
Lumi puts finding what's missing, AI drafts, review, publishing, and restores in one Shopify workflow. Find the empty fields, approve the changes, and keep a record of what went live.
Accessibility, honestly
Lumi runs automated checks based on WCAG on a set number of storefront pages, and shows each issue with its page and element. It sorts issues Lumi can help fix from issues for your developer, and says what still needs a person to test.

Only when you choose to. Lumi fills empty fields by default, batches you start create drafts, and your existing content stays as it is until you publish a replacement. Rewriting existing content is something you pick. Optional automation on Maintain only fills fields that are empty.
Credits count drafts, not products. An alt text, SEO title, or meta description draft uses one credit. A product description draft uses two. If some items fail or you cancel, the finished drafts stay and credits for the unfinished items go back to your balance. Compare plans and credits
Not from a batch you start. Batches you start always create drafts for review, and you compare the current and proposed copy before publishing. On Maintain, optional automation for new products and missing alt text is off until you turn it on. Once on, it starts set to publish automatically, so choose "save as drafts" if you want to review first.
Yes, for changes published through Lumi. Lumi saves what was there before it publishes. For eligible updates, you can preview the previous Shopify value and restore it in a click. If someone edited that field after Lumi published, Lumi won't overwrite their edit.
Lumi drafts from your own product details and photos, and it is instructed not to invent claims like certifications, warranties, or health benefits. You still check the facts in each draft from a batch you start before it goes live.
Lumi installs no scripts, widgets, overlays, or theme code on your storefront. It fills Shopify's own product fields, which your theme already displays.
No. SEO titles go into the page title field under Search engine listing in Shopify. The product title shoppers see on your store stays the same.
Yes. The Free plan includes 100 credits every month for product descriptions, image alt text, SEO titles, and meta descriptions in English, so you can run the whole workflow (find, draft, review, publish) on real products. One-Time Cleanup and Maintain add your brand voice, 17 writing languages, and bigger batches, plus optional automation on Maintain.
