Web/Chrome: You probably have too many cloud services storing your stuff. Xendo allows you to search Google (and all its services), Dropbox, Evernote, Pocket, and plenty more in one place.
Unlike other services that just search your files on cloud storage providers like Dropbox or Google Drive, Xendo searches everything. You can find notes you've written in Evernote, links you've saved in Pocket, and calendar events in Google Calendar. It can even search more work-oriented services like Slack, Hipchat, and Trello.
