Private instant messaging for overseas teams
Private IM for overseas customers: dedicated nodes and multi-region overseas deployment — 100k-member groups, multi-device access, and multi-account login in one client for cross-border teams at scale.
WinTalk is private instant messaging for overseas customers: one dedicated node per customer, joined by node-code search. Regions are Singapore, US East, US West, the Middle East, Japan, and Europe. A single group holds up to 100,000 members, and a dedicated environment supports up to 100,000 people online at once. On Windows, macOS, Android, and iOS, one client can sign in up to 10 accounts at the same time, all staying active. After registration, policy can auto-create groups, auto-join groups, and auto-add friends.
