BRU

BRU is a web-based file renaming tool that works entirely in your browser. Unlike most batch rename utilities, BRU brings AI into the mix: you can describe what you want in plain English — like "add the date to all image files" or "make all filenames lowercase and remove underscores" — and the AI interprets your request and applies the changes. The tool also includes a rule-based mode for those who prefer regex or JavaScript-based renaming, giving you full manual control. All processing happens locally on your device; no files are uploaded to any server.

What makes BRU stand out is its combination of simplicity and power. For quick edits, there are one-click actions like adding a prefix, inserting the current date, or converting text to lowercase. For more complex tasks, the AI mode shines — just type what you need and hit submit. A preview table shows exactly how each file will be renamed before you finalize. BRU also offers specialized companion tools like an AI File Organizer and Photo Renamer, accessible from the main page. The free plan includes 2 AI renames per day with a limit of 50 files per operation, which covers small projects. For higher limits, you can support development via a Buy Me a Coffee.

This tool is ideal for anyone who regularly deals with file organization. Photographers can quickly rename batches of photos by date or event. Developers can use the rule-based mode for regex patterns. Office workers and casual users can clean up download folders or project directories without installing software or worrying about privacy. BRU is straightforward, does one thing well, and respects your data — exactly what a good utility should do.
