Online Collaboration Tools

Ninchat is a web service which offers you the ability to create one or more persistent, online collaboration rooms, where you can text chat and videoconference with up to 12 people concurrently.

Collaborations rooms, or channels, created with Ninchat integrate text, video conferencing and file sharing via Dropbox. These rooms can be set to be "public" or "private" depending on your needs.

The chat history is "infinite" and fully searchable, allowing for effective  asynchronous exchanges, and messages can be exchanged also privately between individual users.

All Ninchat communications are SSL encrypted, there is an open API to extend and customize this service, and the service works across desktop computer and tablets/smartphones (Android only for now).

Basic plan free to use (2 rooms).

Higher pricing plans go from a "Small" 5-room option at $15/mo up to "large" for 30-rooms at $70/mo.
