Tempo AI’s smart calendar has had a good run in the U.S., which it now hopes to replicate on the other side of the Atlantic. The iOS app launched today in the Apple iTunes stores in the U.K. and Ireland. It makes sense for Tempo to go after two of the largest English-speaking countries. Its smart calendar is essentially parsing the language within its customers’ email, appointments and social media accounts to create context for calendar events. Like its fellow SRI Labs spin-off Siri, Tempo is using natural language understanding and machine learning techniques to power a virtual assistant, except in this case it takes the form of calendar rather than a user interface.
