Pi

Pi is Inflection AI's personal AI companion for supportive, friendly conversation by text or voice, on the web and in mobile apps.

Pi, short for personal intelligence, is a chatbot from Inflection AI built to be a kind and supportive conversation partner rather than a productivity tool. It talks by text or voice, with a choice of voices, and is designed to listen, ask questions and respond with empathy, humor and a diplomatic tone on sensitive topics. People use it to talk through a problem, think out loud about a decision, explore an idea or practise a conversation, and it remembers earlier chats. Pi is available on the web at pi.ai and in iOS and Android apps. It is free to use.
