Cheers! spokesman Matt Claridge said the aim was to help young New Zealanders make better choices while out drinking through a channel they use every day.
"Many of us have had a situation where our best intentions to go home early were forgotten once we were out having a few drinks with friends," he said.
"The Sober Self Bot brings to life that original idea you had so that you can remind yourself of those plans. Maybe it's that you wanted to get up early to go to the gym, or take the kids out for a bike ride, or catch up with mates."
Uber New Zealand general manager said people could already get home safely with the push of a button but the app was to help them make good choices about when to call it a night.
"The Sober Self Bot is all about taking this a step further, and giving Kiwis a fun and easy way to keep themselves honest when the peer pressure to stay for another round kicks in," he said.
The bot was part of a wider campaign around responsible drinking which will be launched on the Jono and Ben Show tomorrow night.
