The brightest highlights are clipping.
It tells you what's wrong
A histogram that teaches rather than decorates, and clipping described in a plain sentence.
Muse — a photo library and editor for macOS
Your photographs, in the folders
they already live in.
Muse browses, organizes, searches and edits them — without importing a thing.
Anywhere on disk
Your files, where they already are
Point Muse at any folder — a shoot, your Downloads, a pile of screenshots. Files are read in place. Nothing is imported, copied, moved or renamed.
Every kind of file, and every size of folder
Each type gets a real viewer; anything else falls back to Quick Look. Only the tiles in view are drawn, so two thousand photographs scroll like twenty.
On-device analysis
It organizes itself
Apple's Vision framework reads your images on your own Mac as the library grows — no button to press, no upload, and your own edits always win.

Tags, colors and text you didn't type
Subjects, palettes and any readable words come out on their own — and collections built on a rule keep their own membership up to date.
Non-destructive editor
Edit without leaving
A full editor, one keystroke from the grid. Your original file is never written to — every adjustment is a recipe you can undo, copy onto another photo, or throw away years later.
BeforeAfter
Versions, not overwrites
Snapshot a look, keep several versions of one frame, and paste an edit onto a hundred more.
All the way down
Tone curve, HSL color mix, split toning, grain, vignette, crop and straighten, and your own LUTs.
Import and export
Bring your library, take it anywhere
Years of keywording shouldn't be the reason you can't switch. Muse reads what your old app wrote, and gives it all back on the way out.

Out at any size
Save your own presets for format, quality, bit depth and dimensions, or take a ready-made one.
Or onto paper
Lay a collection out as a paginated contact sheet and save it as a PDF.
Privacy
Yours, and nobody else's
Analysis, search and editing all run on your Mac. Nothing is uploaded for processing, and nothing is measured about how you use it.
App privacy
Data Not Collected
Nothing leaves
That's the App Store privacy label in full. No ads, no telemetry, no accounts.

iCloud sync, if you want it
Your folders, on your disk
Muse works against the folders you already have. Put one in iCloud if you want it on your other Macs — that part is optional.

Back it all up
One backup file holds everything Muse knows about your library. Restore it on a new Mac and your photographs are matched back up automatically.
Sharing
Send a collection as a web page
Publish to your own Google Drive and hand someone a link. There's no Muse server in the middle — there's no Muse server at all.
Your Google Drive
It lands in your Drive
The images upload to a folder in your own Google Drive. Muse can only ever touch the files it put there.
Their controls
The page is theirs to use
They pick the backdrop, open any frame full size, and can save it all as a PDF.

Checked before upload
Stripped before it leaves
Muse verifies the metadata is gone before anything uploads. If it can't, it stops.
