A voice-controlled Windows assistant with a holographic presence — push to talk, give commands, dictate into any window, and get answers from an AI brain that runs on your own machine. No cloud account required.
Join the waitlist — we'll email you the day Viper is available.
Your PC, controlled the way it should be — by talking to it.
Push-to-talk voice chat with natural speech, or just say the wake word. Dictate straight into whatever window you're working in — email, documents, chat.
Open apps, control system settings, set reminders and timers, and run everyday PC tasks with voice commands. Lives in your system tray, always a word away.
Viper ships with built-in AI that installs automatically — no API key, no account, no cloud. Your conversations stay on your PC.
Analyze photos and screenshots with a question — "what's wrong with this wiring?" works as well as you'd hope.
Ask for the weather or look something up — Viper checks multiple sources and tells you when they disagree, with sources cited.
A floating, transparent assistant with a face that moves as she speaks — voice-driven lip sync, click-through so she never gets in your way.
Like everything Grayline makes, Viper is built for people who don't want their life in someone else's cloud. The AI brain runs locally on your PC. No account to create, no subscription keeping the lights on — when it launches, you buy it once and it's yours.
Tell us you're interested — one message, no spam ever.
You'll hear about it the day Viper goes on sale.
Install, say the wake word, and put the keyboard down.
