What is Pi?

Pi is a personal conversational AI product from Inflection AI, designed around dialogue shaped by an individual’s interests and needs. People can chat with it directly in an app, or communicate through text messages, WhatsApp, Instagram, and Facebook. This makes it suited to users who want to ask questions, explore ideas, or maintain an ongoing personal conversation through familiar channels.

The name Pi refers to “personal intelligence,” reflecting its focus on conversations tailored to the person using it. Depending on the subject, it can take on roles such as a teacher, coach, confidant, or creative partner. Pi is therefore a fit for people who value natural back-and-forth interaction and want one conversational tool that can adapt to different personal topics.
