Filera vs Renamer.ai

Filera is a free batch file renaming tool for Linux, macOS, and Windows, designed to rename hundreds of files at once. A visual task pipeline offers find and replace, number sequences, dates, custom text, and case conversion, without scripting or regex. Before applying a rename, Filera shows old and proposed filenames side by side; files on disk remain unchanged until you apply the operation. Filters target files by name, type, date range, or size, and filtered files are skipped. Filera can walk directory trees and subfolders in one pass. You can rename files in place, copy renamed files to another directory, or move them. The app supports metadata-based renaming, but not regex renaming, folder renaming, or undoing changes. Built with Tauri and Rust, Filera is MIT licensed. Linux installation instructions list .deb packages for Debian and Ubuntu, and .rpm packages for Fedora and RHEL. Its Windows installer is not yet code-signed, so Windows Defender SmartScreen may show a warning.

Renamer.ai analyzes file contents with AI and OCR to create descriptive filenames. It handles more than 30 formats, including documents, spreadsheets, images, presentations, vector files, and email files. Users can rename batches, build templates from details such as document type, date, company or person names, invoice information, and project details, or set Magic Folders to rename files when they arrive. The service supports more than 20 languages and can detect a file's language automatically. Listed platforms include macOS, Windows, web, and API; desktop plans include batch renaming and Magic Folders. The free Starter plan allows 25 renames per month, while paid plans range from 200 files per month on Pro to 5,000 on Ultimate. Pro costs $9.95 a month. The web demo has a 100 MB maximum file size. Web uploads are stored on EU servers for up to 24 hours; files processed through the desktop app are not stored on the service's infrastructure. The company says data is encrypted in transit and at rest, and file contents are not used to train AI models.
