Online Collaboration Tools

Gruveo is a secure and free web app which allows you to easily start a video-conference session with anyone without needing to register, download, install or login anything. 

To start a video session you simply input a numeric code (of three or more digits) of your choice on the Gruveo home page and then communicate that code to anyone you want to video call. That's it. Your computer and the other device will automatically create a direct connection allowing your video conversation to start instantly.

An excellent solution for instant video calls that require zero set-up time and which may benefit from secure encrypted communication and anonymity.

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.
