Same rooms, same invites — with a real keyboard. Your phone stays the key to your account; your computer syncs to it.
Both desktop apps are in beta — the Windows build especially is early.
Open the DMG and launch KLATalk — it offers to install itself to Applications. (Dragging still works on macOS 15 and earlier.)
Unzip anywhere and run klatalk.exe. The beta build isn't code-signed yet, so Windows may show a SmartScreen notice — choose "More info → Run anyway".
KLATalk has no passwords — your phone is your key, and it opens your computer too.
