Finally, a product that delivers on the dream of true cross-browser, cross-platform, multiple form factor synchronized bookmarks. If you can set the home and/or new tab page in a browser, you can now have all your bookmarks, arranged exactly the same way, in all your browsers. You heard me correctly: the same bookmarks in every browser on desktop, mobile and tablet.

Pros
Pro Official Android app
If you have need to manage or organize, share or export your bookmarks on the go, Atavi offers an Android app which provides a quick and easy means to do so. The web page interface on mobile is fine for visiting your bookmarks, but the app brings the smooth drag-and-drop and long press inputs that are needed to easily rearrange or share your collection.
Pro Search engine integration
At the top of your Atavi bookmarks page on each browser tab is a search field, which can be set to pass your query to Google, Bing, Yahoo!, or Yandex. There's no need to lose the familiar new tab page search field when switching to keeping your bookmarks with Atavi.
Pro Unique implementation as a browser homepage
Atavi is able to be used in almost any web browser and platform because it bypasses the native bookmark management, instead providing access to your links through a responsive web page. With every new tab opened, your bookmarks appear with all the grouping and sorting options you expect from the native bookmark manager.
Pro Stable browser extensions for Firefox, Chrome, and Opera
Atavi's browser extensions further simplify use of the service by ensuring that new tabs display your Atavi bookmarks and providing a one-click mechanism for importing bookmarks you already have in that browser into your Atavi account.
