The Ask AI panel lets you research across your files in plain language. Answers come from a model running entirely on this device — nothing leaves your system.

Mentions and commands

The composer understands three kinds of reference:
TriggerWhat it does
@fileAttach a file’s contents to the conversation
#folderBring a folder’s listing into context
/commandRun a built-in command — e.g. /find runs a semantic search and hands the hits to the model
Quick-action tiles get you started: Summarize this folder, Find a file, Explain a file, and Perform a file action.

​
Acting on your files

Beyond answering questions, the assistant can do things — create, copy, move, rename, list, read, and delete-to-Trash — through function calling. Every action is:
  • Recoverable — deletes go to the OS Trash; creations and copies never overwrite.
  • Visible — each call streams to the panel as an activity chip and is saved with the message.
  • Yours to approve — file-changing actions happen with your consent.

​
Bring your own model

FilDOS ships a built-in catalog spanning 0.6B to 35B parameters, grouped by family — Llama, Qwen, Gemma, Phi, Mistral, SmolLM, DeepSeek, Granite, and more. Every model runs on your own hardware via node-llama-cpp (Metal on Apple Silicon).
  • One model stays resident; switching disposes the old one.
  • A device probe recommends the best-fitting model for your machine.
  • A per-model customize panel tunes temperature, top-p, max tokens, context window, and custom instructions.
  • You can also add any GGUF from the internet — paste hf:owner/repo, owner/repo, or a direct .gguf URL.
Manage everything in Settings → Assistant.

Conversations are saved

Every exchange — including the files you mentioned and the sources a /find pulled in — is persisted locally, so you can reopen a conversation from the history view and continue it later.
The assistant respects Hide from AI: anything you’ve excluded from indexing is invisible to chat as well.
