Presenting Live Documents – Office updated for the Internet Generation.
Live Documents is an online office productivity suite that gives you the powerful productivity features of Microsoft Office coupled with the collaboration and mobility of Google Docs at a price point that doesn’t burn a hole in your pocket.
Live Documents is the only online office suite that provides “non-lossy roundtripping” for Microsoft Office documents – rest assured that the documents that you import do not lose data or formatting (even documents with esoteric elements that we do not support currently are retained as in the original and can be seen when exported back to Microsoft Office formats).
