File Brain

File Brain is an intelligent local file search engine and document finder for desktop use. It is built to help people locate files on their computer by searching by meaning rather than relying only on exact filenames or keywords, and it is described as privacy-first and completely offline.

Its core capabilities include semantic search, OCR, and automatic indexing. The product says it can search by concepts, meanings, and context; it is resistant to typos, so a misspelled query can still return results; and it supports 1,000+ file formats, including documents, archives, and binary files. File Brain also offers cross-language search, OCR and image analysis for text inside screenshots, scanned documents, and images, and duplicate-file detection by content. The page further says it can connect knowledge across scattered documents and notes. In its Pro offering, it adds conversational AI for asking questions about files, visual understanding for finding scenes in videos and objects in images, and unified search across Google Drive, Dropbox, OneDrive, and network shares such as SMB and FTP.

The tool is shown as a desktop app, with command-line support listed in the feature comparison. Its Free tier includes local file search, fuzzy and typo-resistant search, text-based semantic search, auto-indexing, and command-line support. Paid Pro tiers are sold as perpetual licenses with a one-time payment, and include auto-updates and priority support for one year. The Pro tiers listed are Knowledge Engine, Media Suite, and Cloud Connect, with the higher tiers adding features such as chat with files, similar-file search by text, visual content understanding, cloud storage connections, and remote access with a web UI.

File Brain says it is built for researchers, managers, and others handling complex data.
