Renamer.ai targets the tedious reality of digital filing: folders full of files named things like scan_0042.pdf, IMG_2381.webp or final_final_v2.docx that tell you nothing about their contents. The application reads each document with AI, which means the naming logic adapts to the document's own subject matter rather than a rigid pattern. In practice, a scanned invoice becomes something like Northwind-Consulting-Group-Ltd_22-03-2026_24-067_5780-EUR.pdf, capturing issuer, date, invoice number and amount in one glance-readable string.
The product goes beyond renaming. A Template Builder lets you define the exact variables you care about and describe them in natural language, so the model knows what to extract. The Magic Folder watches a directory you nominate and processes new arrivals automatically, turning a Dropbox folder or a scanner output path into a self-organizing archive. Files can additionally be routed into nested folder trees organized by year, document type, client or issuer.
Privacy is handled with a choice of processing paths: cloud processing for best quality, your own LLM API key to bypass Renamer.ai's servers, or a fully local AI model so data never leaves the device. Files are processed rather than stored, and the company states that customer data is not used to train models. It runs as a desktop app for Windows and Mac and supports over 30 file formats, with roughly 25,000 users and a free tier to test on real documents.
