WHY SOWHAAT

A room with people in it.

Most messengers begin with everything you missed. SoWhaat begins with the people who are here now.

Presence before backlog

Online, away, or free for chat tells you whether now is a good moment.

Conversation before content

No feed, stories, channels, mini-apps, or engagement machinery.

Small on purpose

A focused native app that opens quickly and stays out of the way.

WINDOWS 0.2.09a

A new name, with continuity where it matters.

Existing installations keep their accounts, protected history, saved Preferences and compatible network identity.

A new public name and a consistent signed Windows identity.
Fresh green status artwork, phone and birthday badges, and a clearer About box.
Ctrl+Enter to send, Ctrl+S for status, and a dedicated Shortcuts page.
An aggregate unread count on the taskbar and safer post-update relaunching.
