Bulk Rename Utility is an online application that simplifies the batch renaming of files using two primary modes: AI Mode and Rule Mode. Users can rename files without uploading them, ensuring privacy, as the tool operates directly from the file's directory. The AI Mode allows users to describe their renaming needs, and the AI generates appropriate new file names. Meanwhile, Rule Mode offers a customizable experience with various renaming rules, including character deletion, sequence padding, and regular expressions, catering to more advanced renaming requirements.

The interface of Bulk Rename Utility is designed for user-friendliness, enabling smooth navigation between both renaming modes. It supports local operations, ensuring that only directory and file information is accessed, which enhances user privacy. Compatible with Chrome and Edge browsers on both Windows and Mac systems, this utility stands out for its capability to integrate complex renaming functions, making it a versatile choice for anyone needing to rename multiple files efficiently.
