Humans vs AI

A/B testing OpenAI's GPT-3

This is a friendly competition between human copywriters and copy generated by the new VWO feature powered by OpenAI's GPT-3 API. In this competition, we will test AI-generated copy for headlines, buttons or product descriptions against existing (or new) human-written copy for participating websites. The tests will be conducted on VWO or any A/B testing platform you are using today.
