Workspaces
Personal, Organization and Project spaces with members, departments, roles, multi-step approvals, contracts, files and an audit log — the same rules on web, VietOS desktop and the ViSi app.

VietOS — the AI workspace made in Vietnam
VietOS is a browser-based operating system with the ViSi assistant, built and operated in Vietnam. Create a free account, then work in your Workspace from any device.
Sign-in and most app screens are currently in Vietnamese; an English interface is on the roadmap.
ViSi assistant
Ask in plain language: summaries, cited research, reminders and automations. Phone numbers, emails and ID numbers are masked before reaching AI models.
Sign in your way
Scan a QR code with the ViSi app (2-minute code, you approve on your phone), password with optional two-step verification, and passkeys (Face ID / fingerprint / Windows Hello).
Work across borders
Dates and times follow each viewer’s time zone; invite collaborators anywhere with a link, QR code or VietOS ID.
For organizations
Roll out VietOS to your team
Verify your company domain so employees with a verified company email can request to join; you approve each person. Enterprise plans include VAT invoices and contract-based quotas.
