TitanPad is a free web 2.0 tool that enables users to work collaboratively in a single document. Similar to Google Documents, this online tool allows many people to work simultaneously on the document. Users can chat while working on the document, can import existing documents to work on and also export documents from TitanPad. It also provides the option to view previous versions of the document and includes a time slider to view the entire history of the document.
TitanPad was effectively shutdown on the 31st of December 2017 because of unsustainability.
