Evernote, the memory-extension software I reviewed last month, has just released a client for the Mac (in addition to its Windows and Web-based version). You should be able to download the Mac version here. The company is also expanding its private beta to the first 2,000 TechCrunch readers who sign up here.
In the words of CEO Phil Libin, “The main idea of Evernote is to create an external brain.” Evernote lets you highlight any portion of a Web page and clip it, or take a picture with your camera phone and send it to your PC or the Web. Each of these digital “notes” is archived and can be searched, including any words (even handwritten ones) visible in those pictures. For instance, you can search for “crazy milk sake” and all the pictures of sake bottles will come up, with the the word “crazy,” “milk,” and “sake” highlighted in yellow.
