J.A.R.V.I.S.

A Czech voice assistant for Windows with an Iron Man-style HUD, local actions and LLM conversation.

🔒 Private repository

01 The problem

A personal experiment: how far can a hobby voice assistant go in Czech, controlling the PC and answering freely?

02 What it does

  • Voice commands for apps, system actions and web lookups, Czech text-to-speech.
  • Free conversation through an LLM via OpenRouter, with simple memory.
  • Local FastAPI server and a HUD, packaged for Windows with PyInstaller.

03 Architecture

  1. 01 CorePython: parser, brain, memory, TTS, action handlers
  2. 02 ServerFastAPI for the HUD and remote relay

05 How I worked with AI

My first larger project built together with AI tools. It taught me where agents help and where they quietly produce code nobody understands.

06 What is verified

  • Source exists as a private repository (a Windows voice assistant).

07 Honest notes

  • This is the older voice assistant, not the newer agent operating system I am working on. That one is not published and is not described here.
  • No tests; a hobby project.
