Another tool to help knowledge workers get to what they need quickly. I've been trying Atlas Recall over the last month. The general idea is that it sits on your computer (Mac currently, Windows soon) and keeps track of everything you see. And then if you are trying to recall "where did I see X", you can ask Atlas Recall for help. It does exactly that: will show you what you have seen, whether it was on the web or in a chat session or in documents you've been writing / reading.
