Your whole computer,
in a browser.
SinkOS V2 is a modular, browser-based operating system. Files, writing, chat, calls, slides and an AI assistant, on any device, with nothing to install.
Everything in one desktop
Each module is its own app, and they all share one account and one file system.
Core
The file explorer. Browse, organise and send files, and receive them from other people.
Sink Writer
A word processor that saves to your account, so your documents follow you across devices.
Sink Chat
Real-time messaging with friends, plus opt-in secret chats that are end-to-end encrypted.
Sink Calls
Voice and video calls straight from the browser.
Sink Browser
A tabbed browser with bookmarks, running inside SinkOS.
Sink Charts
A spreadsheet grid with bar, line, pie, radar and scatter charts.
Sink Slides
Build presentations and export them to PPTX or PDF.
Calendar
Keep your events on the taskbar, one click away.
Nexus AI
An AI assistant with voice mode and file attachments, built into your desktop.
Built to be yours
Three things SinkOS is designed around.
Any device
Sign in on a laptop, a school computer or a phone and your files and apps are already there.
Security first
Your OS password is checked on the server, not in the page, and activity is monitored for threats.
Share directly
Send files person to person with a six-digit code. The recipient approves every transfer.
