Guardo.io VS Superdense

Have all yours ‘get back to’ stored in one place. Guardo is the easiest way to save and categorize links, making browsing more productive. On a modern web, you need a place to store links privately and have the ability to quickly and easily search and group them. The browser does not provide you with the tools to organize the links you have saved outside of its own ecosystem. Guardo aims to fix this by making browsing more productive by creating a better way to save links with a simple user interface.
