Etherpad is a highly customizable Open Source online editor providing collaborative editing in really real-time.
Collaborating in really real-time
No more sending your stuff back and forth via email, just set up a pad, share the link and start collaborating!
Etherpad allows you to edit documents collaboratively in real-time, much like a live multi-player editor that runs in your browser. Write articles, press releases, to-do lists, etc. together with your friends, fellow students or colleagues, all working on the same document at the same time. More Info »
All instances provide access to all data through a well-documented API and supports import/export to many major data exchange formats. And if the built-in feature set isn't enough for you, there's tons of plugins that allow you to customize your instance to suit your needs.
You don't need to set up a server and install Etherpad in order to use it. Just pick one of publicly available instances that friendly people from everywhere around the world have set up. Alternatively, you can set up your own instance by following our installation guide
This opensource project is based on the original Etherpad (by Appjet) , made from AppJet Inc. , later acquired by Google which open-sourced the key libraries required to create Etherpad Lite.
