Post Intelligence (Pi) is the world's first AI-based social media assistant. Pi helps users make great posts and gain followers by creating a deep learning model just for them.Pi learns what you post about and what works well with your audience. Once it understands you and your posting patterns, Pi will suggest great content, optimal times, and even personalized topics, so you will always have something to say.The best part is that Pi's skills get better with time, so the more you use it, the better it will get.PI was acquired by Uber in June of 2017.
