I've been working on this in my spare time for a while now. I built it to scratch an itch I was having with keeping track of things I'd come across online.
I wanted something that could; track links in one click, give me visual references of all the stuff I had collected, archive the page as it was when I viewed it and give me ranked full text search across all my stuff. It's pretty beta at the moment so I'm very open to constructive feedback.
