Sparkle

Sparkle is an AI-powered file organizer for Mac that automatically sorts and manages files in designated folders, including cloud storage. It explicitly mentions automated organization, cloud integration (Dropbox, Google Drive), local file access (Downloads, Desktop, Documents, external drives), and privacy controls (only uses file names, deletes data every 30 days). It also offers duplicate file removal and multi-tier pricing. However, it does not appear to offer conversational AI for file interaction, semantic search based on content, or content-based Q&A, as it states it only uses file names and does not access file content.
