Notion AI, a communications intelligence company, launched from stealth with $9.5 million funding and an email app that “predicts what’s important to you with over 95 per cent accuracy”.

The iOS and Android app works with existing email services and claims to save people time and reduce communications stress by predicting which messages are most important to a user, with high levels of accuracy from the outset.

It also improves responsiveness by highlighting items waiting for replies and gives users access to insights about their relationships with the people they email.

Notion believes that through the app it can “uncover the largest social network you already have… buried inside your email history”.

Soon, users will also be able to link Notion to Amazon’s personal assistant service, Alexa, and “talk to their email”.

Alexa can read out important emails, notify users about emails waiting for replies, and even archive, snooze or send messages.

“Today’s communication tools offer little in the way of improving the way we communicate or the underlying relationships behind our conversations,” said Guy Suter, co-founder and CEO.

“Artificial intelligence will improve how people communicate by focusing our time and encouraging behaviours that build stronger relationships.”

Notion AI is based in Ann Arbor, Michigan, and was founded in 2013. The firm prototyped its cloud intelligence platform in 2014 and in 2015 started a private beta of its Android and iOS apps.

Drive Capital and Accel led the Series A round, with participation from Hyde Park Venture Partners and Silicon Valley Bank.

In the future the firm wants to focus on expanding its cloud intelligence technology to power the next suite of features for the Notion app “and beyond”.
