Semantic file search
Search by describing what a file means or contains instead of relying only on its filename or exact keywords.
Instant
Instant is a fully offline semantic file-search app for Mac that finds documents, photos, and scans from natural-language descriptions—without sending files or searches to the cloud.
Local search by meaning
Instant is a local semantic search app for Mac. It lets users describe a file in ordinary language and searches the contents of selected folders, rather than depending only on filenames or exact keywords. Results can include documents, images, and scanned material, with relevant text or passages highlighted where available.
The app is designed for private, on-device file discovery. Its site says that indexing, the search model, files, and searches remain on the Mac, with no account or cloud service required. Instant is offered for macOS 15 and later and is optimized for Apple Silicon.
Features
Text, image, and scan understanding
Processes documents, photos, and scans, including scans without a text layer, so visual and text-based material can be searched together.
Broad local file coverage
Supports PDF, scanned PDF, DOCX, RTF, ODT, Markdown, text and source code, as well as HEIC, JPEG, PNG, WebP, GIF, and TIFF images.
Relevant passage highlights
Shows matching passages or highlighted text alongside results, helping users verify why a file matched the query.
Fully offline operation
Runs the index, search model, and searches locally; the site says files and searches never leave the Mac and no account is required.
Global keyboard access
Opens from any app with Option-Space by default, with support for choosing another shortcut combination.
Use cases
Finding details in personal documents
Describe a contract clause, policy detail, or payment term in everyday language and locate the relevant document or passage without remembering its exact wording.
Recovering scattered notes and memories
Search notes, wish lists, photos, and related files using a remembered idea or event, such as a gift suggestion written down months earlier.
Searching scans and image-based records
Locate information in veterinary records, receipts, manuals, or other scanned documents when the original file has little or no searchable text layer.
Retrieving working materials by context
Use a broad description to find a recipe, draft, speech, or code-related file across selected folders, then inspect the highlighted passage to confirm the match.
