RenameKit

Renamer.ai uses AI and OCR to read the actual content of your documents and auto-generate clean, descriptive filenames. A messy invoice_scan.pdf becomes AcmeCorp_Invoice_$4,500_2024-03.pdf in seconds. Photos get described from visual content, so IMG_0421.jpg becomes Whiteboard_ProductRoadmap_Q2.jpg. Built for accounting firms processing invoices and receipts, law firms organizing contracts and case files, and HR teams managing employee documents. Batch process thousands of files in one pass. Available as desktop apps for Windows and macOS, a web app, and a developer API. Customizable templates match your filing convention. A browser-based option keeps sensitive files on your machine. Unlike rule-based tools like Advanced Renamer or Bulk Rename Utility, Renamer.ai reads what is inside each document, so it works on inconsistent scans and archives where filenames are useless. Free tier: 15 files/month. Paid plans from $9.95/mo. Try it at Renamer.ai.

Renomee is a desktop batch file-renaming application for Windows and macOS. It lets users rename groups of files with natural-language instructions or conventional rules such as prefixes, numbering, find-and-replace, and date formats. For content-aware naming, it can use PDF text and metadata, photo EXIF data, audio ID3 tags, and supported document or image content to generate proposed filenames; OCR for scanned images may require a separate server request. Users can review a preview before applying changes. Typical uses include organizing research papers, invoices, scanned records, photographs, audio collections, and mixed folders with inconsistent names. The application serves individuals and teams managing local files who want consistent names without writing regular expressions. A free daily allowance is available, with paid options for larger batches and ongoing use.
