File Brain

A local AI file search app for Windows, macOS and Linux that searches document contents by meaning and reads text in images with OCR.

File Brain is a desktop search app for people who remember a document's subject but can't recall its name or location. You can describe what you're looking for and search the contents of files on your computer.

Search by meaning: Combine semantic and full-text search with typo tolerance, and search in one language for documents written in another.
Text in images: Use OCR to find words inside screenshots, images and scanned documents.
Document and archive search: Search content in PDF, Word, Excel and PowerPoint files, as well as archives and binary files.
Automatic indexing: Keep the search index updated as files change, with a dashboard showing indexed files, storage usage and recent additions.
Duplicate detection: Identify files with matching contents even when their filenames differ.

The free app is open source under GPL-3.0 and supports Windows, macOS and Linux. All indexing and processing happens locally. It reads your files without modifying or deleting the originals.

File Brain requires Python and Docker, and initial setup downloads the required components. It can run on a CPU, with optional NVIDIA GPU support for faster indexing.
