Every field, every photo
Luxii is the metadata editor built into Lightroom Classic.
It's a Lightroom Classic plugin for metadata, not a standalone web tool: Luxii runs inside Library ▸ Plug-in Extras, reads the frame Lightroom already rendered — develop and crop applied — and writes real metadata straight into your catalog in the same click. Here's exactly what it writes, and why each field matters.
What Luxii writes
Title, Headline, Caption, Alt Text, Keywords
As a photo metadata editor, Luxii writes five fields in the same click — title, headline, caption, alt text, and keywords — into the same standardized IPTC and XMP fields that Lightroom, portfolio sites, stock platforms, and Google Images all read. Here's what each field is, how Luxii fills it, and why it's worth having.
Title
What it is: the short name attached to the file — the label Lightroom's grid view, a portfolio site, or an importing CMS shows instead of a filename. What Luxii does: it looks at the rendered frame and writes a specific, descriptive title for that exact photo — never “IMG_4471,” never the same title repeated across a burst of near-identical frames. Why it matters: a client scrolling a gallery, or a CMS pulling in your export, sees an actual name for the photo instead of a camera-generated number.
Headline
What it is: a one-line summary, longer than the title and shorter than the caption — a quick description of the scene. What Luxii does: it writes a specific, human-readable line for the photo, distinct from both the title above it and the caption below it. Why it matters: it's a field almost nothing else in this space writes — in Luxii's own scan of every Lightroom AI tagger it could find, none generated a headline — so it's what shows up as the descriptive line on portfolio and CMS listings that pull metadata in.
Caption
What it is: the longer, plain-English description of what's actually happening in the frame — the subject, the action, the setting. What Luxii does: think of it as a photo caption generator built into your catalog — it looks at the rendered photo itself, not just its filename or folder, and writes a natural sentence describing the scene. Why it matters: this is the text that travels with the photo when it's embedded on another site or uploaded to Flickr — the context a viewer gets when they land on the image itself, not your gallery page.
Alt Text
What it is: a description written for people who can't see the photo — read aloud by screen readers, and read by Google when it decides how to index an image. What Luxii does: it acts as an alt text generator for images, writing alt text as its own field, separate from the caption, focused on accessibility rather than storytelling. Why it matters: it's what makes a portfolio usable for blind and low-vision visitors, and it carries real weight for Google Images SEO — Google reads this field when deciding whether, and how, to surface a photo in search.
Keywords
What it is: the searchable terms attached to a photo — subject, setting, style, mood — the words someone would actually type to look for it. What Luxii does: it writes a set of specific, real search terms for the photo, not a pile of generic tags. Why it matters: this is the field that makes keywording images worth doing at all — a portfolio's internal search, Lightroom's own keyword filter, and stock platforms all match against these words instead of your name.
See the difference
Before and after: blank export vs. fully tagged
No title. No caption. No alt text. No keywords. Just a filename and whatever a camera happened to embed at capture — nothing a screen reader, a stock search, or Google Images can read.
A specific title, a headline, a plain-English caption, accessibility alt text, and a real set of keywords — written into the same photo, before it ever leaves your catalog.
Same photo, same pixels, same crop. The only difference is whether anything outside Lightroom can read it.
Batch processing
Batch edit photo metadata: your whole catalog, not one photo at a time
Luxii is built for volume. Select a folder in the Library — ten photos or a thousand — and run Tag Selected Photos once; Luxii works through the entire selection, writing all five fields to every frame without you touching each photo individually. Take a 500-photo wedding gallery: instead of hand-typing a title, caption, and keyword list five hundred times, you select the folder, click once, and walk away.
Every photo tagged — all five fields, written in one call — costs exactly 1 credit, and the $39 one-time license includes 500 credits to start, enough to tag that entire wedding gallery in a single purchase. Credit packs top you up after that.

Why this gets you found
Google Images, Flickr, and every stock platform read the metadata attached to a file — title, caption, alt text, keywords — not the pixels in it. A technically excellent photo with an empty title field and no alt text is effectively invisible to all three: nothing for Google to index, nothing for a stock buyer's search to match, nothing for Flickr's own search to surface. Photo quality doesn't change that calculation — a blank metadata field reads the same to a search algorithm whether the photo behind it is a phone snapshot or a print worth framing. Luxii closes that gap: every photo gets a real title, caption, alt text, and keyword set the moment you tag it, so the work you already did behind the camera has something to actually be found by.
Lightroom's keyword panel vs. Luxii
Lightroom's own Keywording panel is a blank text field — you type every tag by hand, one photo or one manual batch-apply at a time. Luxii fills that field automatically, and writes four more fields the panel has no place for at all.

- Touch exposure, color, crop, or any other Develop setting — or your ratings and flags.
- Preserve existing metadata by default — it overwrites a field whenever it generates a new value for it, without checking whether something was already there.
- Replace Lightroom as a photo editor — Luxii writes metadata, it doesn't retouch, crop, or batch-edit pixels.
FAQ
Questions about Luxii's features
How do I add keywords to multiple photos at once in Lightroom Classic?+
Select the photos in the Library module — as many as you want, from a handful to a full shoot — and run Library ▸ Plug-in Extras ▸ Luxii: Tag Selected Photos. Luxii writes keywords, plus title, headline, caption, and alt text, to every photo in the selection in one pass, at 1 credit per photo. There's no separate batch command — it's the same command whether you select one photo or five hundred.
Does Luxii generate alt text automatically, or do I still write it myself?+
Luxii writes alt text automatically — you don't type it yourself. Running Tag Selected Photos writes it straight into the catalog with no review step in between. If you'd rather check the wording before it's written, run Preview Tags for Selected (no write) first — it shows you everything Luxii would generate without saving anything, so you can review before committing. Most photographers just run Tag Selected Photos directly and skip that step.
Does Luxii edit or retouch my photos / change Develop settings?+
No. Luxii only writes metadata — title, headline, caption, alt text, and keywords. It never touches exposure, color, crop, or any other Develop setting, and it never changes your ratings or flags. Your edits are exactly as you left them, before and after running it.
What's the difference between Lightroom's built-in Keywording panel and Luxii?+
Lightroom's Keywording panel is an empty text field — you type every tag yourself, photo by photo or via manual batch-apply. Luxii fills that field automatically, and writes four more fields the Keywording panel has no place for at all: title, headline, caption, and alt text.
Does this metadata actually help my photos show up in Google Images or on stock/Flickr?+
Yes. Google Images, Flickr, and stock platforms all read the metadata attached to a file — title, caption, alt text, keywords — to decide how to index and surface it; they don't parse pixels. A photo with those fields blank has nothing for those systems to match against, regardless of how good the photo is. Luxii writes all five fields on every photo it tags, so there's something there to be found.
If my photos already have some metadata, will Luxii overwrite it?+
Yes. Luxii overwrites a metadata field whenever it generates a new value for it — it doesn't check whether the field already had something in it first, so treat it as a replace, not a merge. If you've hand-written captions or keywords you want to keep, don't run Luxii on those photos, or run Preview Tags for Selected (no write) first to see what it would change before it writes anything.
