Twiddla is a free, no-setup, web-based meeting playground. Mark up websites, graphics, and photos, or start brainstorming on a blank canvas. Voice and Text chat too!
Twiddla is a real-time online collaboration tool. Its beauty is in its simplicity and accessibility: no plug-ins or downloads, no need to work around complex firewalls, no advanced scheduling. It’s available 24-7 and the only requirement is a computer with an internet connection and a web browser. It’s browser-agnostic, user friendly, and probably more fun than you're supposed to be having at work.
