About Lumen
Lumen is for the pile between making and finding.
It is a Mac app for people with more images than their filenames can explain.
Your files already live in folders. Lumen helps you get useful work out of them without making you move everything into a new library.
What Lumen does
Lumen helps you manage a growing image folder, find a file from partial memory, compare similar options, and export a smaller set you can use.
It shows folders as image walls, searches words and appearance, reviews duplicates, keeps favorites and rejects, and creates resized copies or contact sheets.
The app stays focused on the work between “I know this file exists” and “I have the files I need.”
What Lumen is not
Lumen is not a cloud archive, account system, network image service, or full image editor. It does not require an import library, and it does not change original pixels when you browse, search, compare, tag, or export.
Rename, move, and Trash are separate actions that you choose explicitly. The index and generated data stay on your Mac.
Built for the next image-heavy day
AI generations, screenshots, references, product shots, exports, variants, diagrams, and photos all create the same basic problem: too many files and too little time to find the right one.
