Online Collaboration Tools

Kollaborate.io is a full-featured real-time collaboration app which allows you to instantly meet with customers, students or teammates without needing to login, install or download anything.

Kollaborate.io integrates video conferencing, VoIP, whiteboarding, document and image sharing, text chat, as well as the ability to auto-archive content and to easily invite other people into a meeting.

Whatever you load, resize or move on the collaboration desktop is also resized and repositioned for everyone else. Everyone sees the same thing.

One unique feature of Kollaborate.io is its clutter-free interface, which completely disappears in the background when it is not needed. 

Definitely worth a try.

Free version available.

Pro versions ($9.99 or $29.99/mo) provide ability to have private and password-protected meetings and with the more expensive plan, to access the archive and schedule meetings.
