ThorOS 0.5 — first-boot Welcome window
ThorOS 0.5 — AI-first, local-first, voice-driven Linux
ThorOS is an operating system built around a local AI assistant. A voice assistant — "Jarvis" by default, rename it to anything — drives your desktop, opens and controls apps, writes documents, and answers questions. 100% local: no cloud, no account, no telemetry. Built on Debian 13.
✨ New in 0.5
A friendly Welcome window now greets you on first boot. It shows live setup progress (you can watch the AI download instead of wondering if the machine froze), then walks you through talking to your assistant — say "Jarvis", rename it, what to do if something's slow. A "Getting Started" entry is also added to the apps menu to revisit the tips anytime. All the under-the-hood reliability fixes from 0.4 are included.

Install
- Write the ISO to an 8 GB+ USB stick with balenaEtcher or Rufus.
- Boot from it and choose Start installer (or Live system to try it without installing).
- On first boot the Welcome window appears and shows progress while it auto-detects your GPU and downloads the local AI model (~5 GB — needs internet, ~10–20 min). The assistant is ready once that finishes.
- Say your assistant's name (default "Jarvis") and start talking — or open the text-chat window.

First steps & troubleshooting
- Be patient on first boot. ThorOS spends ~10–20 minutes (one time, needs internet) downloading its AI model — the Welcome window shows the live percentage. Jarvis says "I'm still getting set up" until that finishes — that's expected, not a bug.
- Talk to it: say "Jarvis" then your request — "Jarvis, open Firefox", "Jarvis, write a thank-you note", "Jarvis, what's 15% of 240?". No microphone? Use the Jarvis Chat window.
- Rename it: say "Jarvis, call yourself Athena" — then just say "Athena." The name is the wake word (no "hey").
- Replies slow? On a PC with an NVIDIA card, the fast GPU driver finishes installing on the first reboot — restart once and it speeds up a lot.
- Check the AI downloaded: open a Terminal and run

Notes for this release
- Hardware-agnostic: boots on any 64-bit PC. An NVIDIA GPU is auto-detected and used for fast responses; it also runs CPU-only (slower for the 8B model).
- Network firmware + SSH are included; the installer configures networking with DHCP.
- Internet is needed once on first boot to fetch the AI model; fully offline-capable afterward.
Requirements
- 64-bit PC · 8 GB+ RAM (16 GB recommended) · ~25 GB disk
- Microphone + speakers for voice (or use the text-chat window)
