Microsoft and Genee, a schedule planning service, jointly announced this week that Microsoft would acquire the company.

Genee, which launched in 2014, is powered by artificial intelligence. The purchase of the company will aid Microsoft in building Office 365 productivity software. Co-founders Ben Cheung and Charles Lee will join Microsoft and help develop features for Office 365. Genee will shut down service on Sept. 1.

“As we continue to build new Office 365 productivity capabilities and services our customers value, I’m confident the Genee team will help us further our ambition to bring intelligence into every digital experience,” Rajesh Jha, corporate vice president for Outlook and Office 365, said in a statement.

After it closes service, Genee will no longer send users reminders and agendas from their calendars, but existing calendar entries will remain.

Cheung and Lee announced the acquisition on the company website, saying that Microsoft is the “leader in personal and enterprise productivity, AI, and virtual assistant technologies.”

Jha boiled down how Genee works in a blog post:

“Say you want to meet a potential customer, Diana, for coffee. Simply send an email to Diana and copy Genee, like you would a personal assistant. Genee understands that you want to ‘Find a time to meet with Diana for coffee next week’ and will streamline the process by emailing her directly with appropriate options that work with your calendar and preferences. Genee will even send out the meeting invite on your behalf – freeing up your time.”

Further details of the acquisition were not disclosed.
