## What is Without?

AI Powered Sustainability! Without is a social platform to encourage and learn about sustainable initiatives. Progress and contributions can be tracked so everyone can do their part to making the world a more sustainable place. 

Accept challenges, earn points, challenge others and join teams to work together on common causes.

Without enables users to create challenges for their community to voluntarily abstain from certain activities, such as conserving energy by turning off lights for a day. By focusing on actions that resonate with local communities, users can effect tangible change while learning practical ways to reduce their carbon footprint through daily habits. 

Participants earn points for their involvement, and the educational platform Watsonx.ai offers insights to deepen their understanding of the environmental impact of their choices. Additionally, Watsonx.ai categorizes user-generated challenges, aiding others in finding challenges aligned with their interests.

Benefits of completing challenges accumulate and show you your contributions per category as well as those by the teams you join.
