Nymos overview

Nymos is a Mac app that renames files in bulk by reading what is actually inside them.

Drop in a folder or files and Nymos reads each file; text, metadata, EXIF, with built-in OCR for scans, then suggests one clear, findable name. Nothing is renamed until you approve it. Review the batch, edit any suggestion inline, apply one file or all of them, and undo a whole batch afterwards from the rename history.

What it reads

57 formats—PDF, Word, Excel, PowerPoint, OpenDocument, Pages, Numbers, Keynote, images (JPEG, PNG, HEIC, RAW), audio, and video named from their embedded details.

Naming that fits your system

Templates put the date, vendor, subject, and amount in the order you want. Add Finder tags, move renamed files to a destination folder, or set a watch folder that handles a download the moment it lands. A Finder service and a menu-bar icon put Nymos one right-click away.

Three languages (separate settings)

The interface runs in Dutch, Spanish, or English—and the language Nymos writes filenames in is its own setting. A Dutch consultant with a Spanish client does not have to pick one.

Two ways to run it

Nymos subscription: Documents are processed in the European Union.

What's new in version 1.1.0

Organize files: sort a whole batch into folders. Point Nymos at a folder and it proposes subfolders for the batch; rename, describe, add or remove them before agreeing. Files are then renamed and filed in one pass — nothing moves until you approve, and History can put everything back in one click. Part of the Nymos plan.
A compact list view for bigger batches, next to the tile view.
Show in Finder on every file row.
The first suggestion after opening the app arrives faster.
