Your PC.
Your voice.
Your assistant.
Nexus is a smart AI voice assistant that lives on your Windows PC. Say “Nexus” and just talk — it opens apps, answers, sees your screen, types for you, and runs your whole computer. Hands-free. Private. Local.
One-time payment. No subscription. Ever.
An AI that actually runs your computer —
by voice, hands-free, on your machine.
No cloud round-trip. No "as a large language model" excuses. Just say it — Nexus does it.
Talk naturally
Say "Nexus" or hold F8 and speak. Real AI understands what you mean — no rigid commands.
Private by design
LOCALThe AI brain runs on YOUR PC. Conversations stay on your machine — not in a big cloud.
Sees screen & camera
"What's on my screen?" or "What am I holding?" — AI vision looks and describes.
Live info, always current
News, weather, live crypto prices (BTC, ETH, SOL, memes), exchange rates — read aloud.
Gesture control
Air mouse with your finger, AR gesture canvas, face auto-lock when you step away.
Runs your PC
Opens apps, types for you, plays songs, screenshots, volume, shutdown — all by voice.
16 languages
Switch by voice: "Nexus, speak Spanish." Natural spoken replies in any of them.
Self-installing & self-healing
One file installs the app, AI engine and model. Re-downloads anything missing on its own.
