Nymos
Nymos is a macOS desktop application that uses artificial intelligence to rename files in bulk by analyzing their content rather than their filenames. It supports 57 file types, including PDFs with built-in OCR, Office documents, Pages files, photos, and text files. The app reads the document's content, extracts key fields such as date, vendor, and amount, and suggests a structured filename based on user-defined templates. Users retain full control: Nymos never renames files automatically; every suggestion requires explicit approval, with options to edit inline, apply one, or apply the entire batch. It includes features like watch folders for automatic analysis of new files, undo and history for reverting changes, and fast concurrent processing to handle large batches quickly. The app also supports multilingual naming, preserving the original language of each document or normalizing to a chosen language. Nymos offers two operational modes: a managed subscription where the AI processing runs on Nymos servers within the European Union, and a self-managed one-time purchase where users bring their own AI provider keys (Anthropic, OpenAI, Gemini, and others). Both modes include a free trial of 60 documents. The application is designed with privacy in mind, sending document content directly from the Mac for analysis and discarding it afterward, with no analytics or tracking.

Problem solved
Nymos addresses the common problem of messy file names, especially for scanned documents, invoices, receipts, and other files that often have meaningless default names like 'scan_2847.pdf' or 'Screenshot 2026-03-26.png'. By reading the content, it produces descriptive, searchable filenames that make files easy to find later, reducing manual renaming time and improving digital organization.
Use cases
- Organizing a cluttered Downloads folder by renaming PDFs, images, and other documents based on their content
- Batch renaming invoices and receipts for bookkeeping with consistent naming templates
- Processing scanned documents by extracting text via OCR and generating meaningful filenames
- Renaming photos based on visual content or metadata to replace generic camera filenames
- Standardizing filenames across a team or department for easier retrieval
- Automatically renaming files as they arrive in a watch folder, such as a Scan folder
Audience
- Business Users
- Startups
Pros
- Reads file content, not just filenames, including OCR for scanned documents
- User approval step prevents unwanted renames
- Flexible templates with live preview
- Watch folder automates analysis without automatic renaming
- Privacy-focused: no permanent storage, direct processing, no analytics
Cons
- Only available for macOS, no Windows or Linux version
- Monthly subscription cost for managed mode after 60-document free trial
- Requires internet connection for AI processing (unless using local compatible endpoint, but still needs AI service)
- Limited to 57 file types; some specialized formats may not be supported
- Self-managed mode requires technical setup (API keys) and additional AI provider costs
