Greplin does the same thing but for your online data that you store on Facebook, Twitter, LinkedIn, Google Voice, Dropbox, Gmail and a bunch of other services. You can run a query and find public and private data on those sites. Tweets including DMs are shown as well as digging into the transcripts of your Google Voice voicemail.

Greplin uses OAuth and other APIs for authorization, so they never see your third party credentials. Since Greplin’s searches work on a variety of online sites it is invaluable to the small business owner who does business online by saving them a lot of time locating the exact information they need when they need it.
