In an increasingly data-oriented world, sifting through mounds and mounds of information quickly becomes more and more important. Look at tools like Google Desktop and the Microsoft Search built into Windows Vista. They are all about finding information quickly and efficiently.
It is with this goal in mind that Xobni developed their software. Being able to click on an e-mail and see everything about that contact is an extremely valuable tool. Automatically, Xobni has extracted the phone number from my contact’s signature, listed everyone else in my network that this contact has communicated with, as well as putting the files and conversations with this contact at my fingertips. But Xobni goes further than that by actually quantizing the data and informing me just how important this contact is to me (in a strictly e-mail sense of the word – my wife won’t be happy to find out that she’s #5). Having this data handy helps to better prioritize and respond to "critical" items in your inbox more efficiently. My day is freed up from reading UPS shipping notices and standard report reminders and I can focus on doing my work, with the knowledge that Xobni is watching my inbox for one of my top e-mailers for me. If one of my contacts has multiple e-mail addresses, Xobni automatically groups them together and shows me all communications with this person, not just from the e-mail address they sent me e-mail from.
It is an Outlook search engine on steroids, allowing a much quicker path to recent e-mail to and from each contact. I would highly recommend it to people like me that have 8 GB mailboxes and desperately need to bring some order to their lives.
