Every screen-share tool asks the other person to install something, sign up, or click through a warning. TabConnect does not. You start from the Chrome or Edge toolbar, pick one tab, and hand over a short code, a link or a QR code. They open it in any browser, desktop or mobile, and they are watching. Freeze the view, lock the room, cap viewers, chat, send files up to 25 MB, use a laser pointer or pass over remote control. Free, and it still connects on locked-down corporate networks.
