No. This is a fundamentally different idea. This is not a bookmarking/archiver/knowledge base/search engine. For my personal searchable knowledge base I personally use DevonThink. This tool is crazily different -- it screenshots your screen and makes your entire screen history searchable. That's game-changing because it captures information that you don't consciously choose to save or store. That's a whole class of information that's not available with existing tools.
