Xendo is an online research tool that provides unified search across cloud-based storage (such as Dropbox, Evernote, Google Drive, OneDrive) and email (such as Gmail, Office 365) and other services such as Slack, Trello and Asana (25 integrations to-date). Xendo offers advanced search capabilities such as proximity searching (looking for term or phrase within a number of words of a second term or phrase). Xendo uses OCR (Optical Character Recognition) to make scanned documents searchable. For some services, Xendo offers a content preview to speed research.
