AI Renamer is a desktop application for macOS and Windows that uses artificial intelligence to automatically rename files based on their content. It supports images and documents, offering smart recognition of image content, EXIF data, and document text. Users can process files in batches with a drag-and-drop interface and preview changes before applying. The app provides flexibility with local model support through Ollama and LM Studio for offline use, as well as cloud-based options. Custom instructions allow personalized naming patterns.
