Zoho announced early this morning that they've taken the first steps toward making Zoho Writer available as an offline app using the Google Gears tool. Initially the docs saved offline will be read only but full offline functionality is planned.
We are taking our first steps towards offering Zoho Writer offline. With this update, you’ll now be able to access all your documents offline (Mac or PC) in read-only mode. We will offer offline editing capabilities in the coming weeks.
Zoho Writer Offline capabilities is based on Google Gears. Many thanks to Google for a great open source project. We plan to support and contribute to this project.
A new commenting feature has also been added. A video showing the offline capability is available in the blog post announcing the new features.
