Files are indexed and processed entirely on your Mac, so your documents, recordings, and screen memory never upload to a cloud AI provider and search keeps working offline.
Query the contents of PDFs, Office and Apple documents, design files, code, images, audio, and video, returning the exact page, line, or timestamp instead of just a filename.
Recall meetings, chats, dashboards, and shared screens that were never saved as files, then jump straight back to the moment you need.
Auto-organize folders with live criteria, find and remove duplicate files, rename files based on their content, and convert documents, invoices, images and videos into structured CSV.
