File Brain

Your Local AI Search Engine

Find what you mean, not just what you say. File Brain runs locally on your machine to index and understand your files.

What is File Brain?

File Brain is a desktop application that helps you find files instantly using natural language. Instead of remembering exact filenames, you can ask questions like "flight ticket invoice", and File Brain uses AI to understand the meaning and show the relevant files.

Key Features

• 🧠 Find what you mean: Uses advanced Semantic Search -in addition to full text search- to understand the intent behind your query (e.g., search for "worker", find documents mentioning "employee").
• 📝 Typo Resistance: Robust against typos. Search for "iphone" even if you typed "ipnone".
• 📄 Supports Everything: Extracts the content of over 1400+ file formats (PDF, Word, Excel, PowerPoint, images, archives, and more).
• 🌍 Cross-Language Search: Search in one language to find documents written in another (e.g., search for "Chair", find documents mentioning "Silla" -in Spanish-).
• 🚀 Fast Matching: Search results are shown within milliseconds, not minutes.
• 👁️ OCR Support: Automatically extracts text from screenshots, and scanned documents.
• ⚡ Auto-Indexing: Detects changes in real-time and updates the index instantly.
• 🛡️ Read-Only & Safe: File Brain only reads your files to index them. It never modifies, deletes, or alters your data in any way.
• 🔒 Privacy First: All indexing and AI processing happens 100% locally on your machine. Your data never leaves your computer.

Why File Brain?

Most search tools look for exact matches of filenames or content. File Brain goes further by understanding meaning, tolerating typos, and extracting text from images. See how it compares to other popular tools:
