Nymos

Nymos is a Mac app that renames files in bulk by reading what is inside them. The homepage puts it plainly: Nymos reads your documents, invoices, photos, PDFs and more. Not the filename, the contents, which is a distinction that anyone with a Downloads folder full of scan_0043.pdf and IMG_8821.jpg understands in their bones.

The honest engineering details are on display. It processes text, embedded metadata, and EXIF, runs built-in OCR over scanned pages, and supports fifty-plus formats. The dealmakers sit right under the download button: 60 documents free, no account, no credit card, and review first, nothing renames without your approval. That last one matters more than any model quality claim, because the nightmare scenario of bulk renaming is an AI confidently mangling two thousand files at once, and requiring a human review step before anything touches disk is the only sane architecture.

Everything runs locally on the Mac, so contracts and scans never leave the machine, a selling point for anyone whose files are covered by confidentiality obligations.

Who is this for? Consultants, accountants, designers, and researchers sitting on years of badly named files, plus anyone who scans paper and hates the resulting filename soup. It is a native Mac tool, free to start, info@nymos.ai is public as info@nymos.io, and the sixty-document trial is exactly enough to test it on one real disaster folder before paying.
