Gmail has some pretty great advanced search features, but it can't search the content of any documents you may have floating around your email. Web service Attachments.me brings even more advanced searching to your Gmail inbox, and we've got beta invites.
Attachments.me will not only search the content of your attachments, but it will tag your attachments for you, let you search by file type, and even bookmark those searches for later. And like every other web service that seems to come out these days, you can send those attachments straight to Twitter and Facebook. Check out the video above to see it all in action.
Attachments.me is in beta right now, but we've got 2000 invites for Lifehacker readers to give it a try. To check out Attachments.me, just head to their homepage and sign up for a new account using the invite code
lifehacker. Please don't email us for invites!
