Instant

Instant is a desktop search utility that finds local files on a computer based on natural language descriptions.

Instant is a desktop search tool designed to help users locate files on their Mac by describing their contents in plain English. Users type what they remember, and the software searches text documents, photos, and scans to highlight relevant passages. It supports formats including PDF, DOCX, RTF, ODT, Markdown, source code, and image files like HEIC, JPEG, PNG, WebP, GIF, and TIFF. Operating entirely offline with a local search model, the application ensures complete privacy by keeping all files and searches on the device. Users summon the interface from anywhere using a keyboard shortcut to search selected folders without needing an account.
