What is VixOS

VixOS is a web operating system. Once you log in, your browser opens a desktop with windows, a taskbar and apps, just like a computer, except it goes wherever you have the internet. Your account, files and settings are the same on every device.

In the middle sits the AI bubble. Type or say what you want and it opens an app, writes a document, prepares a presentation or builds you a brand new app. VixOS is made by Vixtab in Czechia.

What VixOS can do

AI bubble and voice

Type, or say “hey vix”. The bubble opens apps, changes the look, writes text or does the work for you. You can also just talk to the AI out loud.

Apps from one sentence

Describe the app you want and VixOS builds it, tests it and installs it for you. Ready-made apps are waiting in Vix Store.

AI agents in the background

Agents work on a schedule: they draft emails, do research or prepare a daily summary and leave the result in VixOS.

Files made by AI

PDF, Word, Excel, PowerPoint, video and audio straight into your folder, with file viewers built into VixOS.

Mail, calendar and widgets

Mail, calendar, tasks, weather, a calculator and more widgets you arrange on your desktop.

Studying
