Editing documents in groups can be a challenge. Versioning systems like subversion or cvs help your group to keep a consistent copy of your document, but don't provide realtime collaboration. Wouldn't it be great to edit the same document, live, in realtime, together with everyone in your group?

Time for SubEthaEdit

With SubEthaEdit you can. The idea of collaborative editing has been researched for years, with notable results. But now for the first time it has been implemented in a way you actually want to use: A sophisticated technique allows all users to type anywhere in the text without locking parts of the text for other users, making SubEthaEdit just as easy to use as a traditional text editor.


Everyone's invited

Using Mac OS X's unique Bonjour features you don't have to edit long lists of preferences anymore, configuring servers and clients. It's as easy as editing a local file, just announce your document and type away. You can even see who is available for collaboration on your network and invite them by dragging and dropping them to your document.

Programming extreme

XP LogoSubEthaEdit's real power unfolds when programming in teams. Pair programming is taken to the next level with multiple input foci, text coloring and other cool awareness features. No more fights for the keyboard or running around the desk.


SubEthaEdit is a great tool for showing, teaching and helping with any text based task from programming to writing essays. SubEthaEdit allows you to set collaborators in a "Read only" group, preventing them from writing anything, but ideal for showing something or working in turns. By using invitations students can ask for help on a specific problem.

Take notes

SubEthaEdit has been used to take notes together at conferences like O'Reilly's OS X Conference, Open Source Convention, Emerging Technology Conference, PyCon, NECC, WWDC and Siggraph. With its new web page export feature you can store these notes with all collaborative metadata intact.
