Zush develops an AI file renamer and naming-first file organizer for macOS and Windows. The desktop app reads the content of screenshots, PDFs, photos, RAW images, design files, Office and iWork documents, audio, and video, then turns unclear filenames into descriptive, searchable names. Zush supports batch preview, Rename History with undo, Folder Monitoring, reusable Templates, 145+ Naming Blocks, Custom AI Blocks, Finder tags and metadata, and 104 file extensions. Users can choose managed Zush Cloud AI, bring their own API key, or run supported analysis locally with built-in Local AI, LM Studio, or Ollama.
