Your files, finally connected.
FilDOS is an Open-Source AI-native File Browser for your PC. Search by meaning, chat with your documents, and see how your work connects. All running locally on-device.
The file browser built for the AI era
FilDOS looks like a familiar file browser, but underneath it builds a private semantic index that understands what's inside your files.
Search by meaning
Ask for ‘receipts from tax season’ or ‘the part of the lecture about kestrels’. FilDOS finds documents, photos, audio and video by meaning, and opens them at the page or moment that matched.
Private, on-device AI
Everything stays on your device. Models run locally, your index lives locally, and your files never leave your machine.
Chat with your files
Ask questions across your documents and get answers with citations. Tag files, use slash commands.
File manager first
List, grid, gallery or column view, and Quick Look on Space. Sort, group and filter however you work.
Your clouds, one window
Browse local folders and cloud storage side by side with one consistent interface.
Open source
Built in the open on GitHub. No accounts, no subscriptions, no telemetry.
More than a file browser
Canvas
FilDOS builds a living map of your files and the relationships between them. Click any file to explore its world.
Research mode
Searches across your files, reads what it needs, and answers with sources you can open.
Hide from AI
Conceal your files from search and AI to never have the agent accidentally read your private files.
Plug any AI model
A built-in catalog of local models: Llama, Qwen, Gemma, Phi, Mistral, DeepSeek or paste any GGUF from Hugging Face. Everything runs right on your hardware.
Private by architecture, not by promise
