What is Nymos?
Nymos is a macOS app that uses AI to intelligently rename files in bulk by reading file content (including PDFs with OCR) rather than just filenames. Users review and approve all suggestions before any files are renamed, ensuring full control over the renaming process.

Frequently asked questions about Nymos
Does Nymos automatically rename my files?
No. Nymos suggests new names based on file content, but nothing is renamed until you explicitly approve it. You can edit suggestions inline or reject them.
What file types does Nymos support?
57 file types including PDFs (with OCR for scans), Office documents, Pages, images, text files, and more.
Is my data private?
Yes. Documents are sent directly from your Mac for analysis and then discarded—no permanent storage, no training on your data, and GDPR-compliant EU processing on the subscription plan.
Can I use my own AI provider instead of subscribing?
Yes. The self-managed option ($79 one-time) lets you bring your own API keys from Anthropic, OpenAI, Gemini, or any OpenAI-compatible endpoint.
