Realtime location sharing by sending an email. (Winner, Calhacks 2014.)
There are many location sharing platforms, but for the most part, they all require their own proprietary app.
Yat changes this.
Simply send an email to your friends and CC Yat's email bot. A secure session is generated and every user is emailed an invite. The invites contain a unique link which direct users to the webapp. Here, users can see each other's locations in a very ephemeral way. No apps to download, no accounts to remember. Simple.
Yat also uses wit.ai's powerful natural language processing to extract meaningful data. It can identify both an address and a time in your email and customize your event accordingly.
Yat was built with Qiming Weng at Calhacks 2014, and won the SendGrid Sponsor Prize for best use of the Sendgrid API.
