What is Pi?

Pi is a personal AI assistant launched by Inflection. Its official introduction is "Hi, I'm Pi--your personal AI". It is designed to support you, be intelligent and available at all times. Unlike task-oriented assistants, it places more emphasis on "helping you think things through", "cheering you on" and "being a companion when you just want to chat". When you open the page, it will first ask you what it should call you, and the overall atmosphere is warm and natural, like a friend who is online at all times rather than a cold tool. For many users, it is more like a "confidant" for emotions and thoughts rather than a productivity tool, making it suitable for slow-paced in-depth conversations. The page has no complicated tool stacking; you can start chatting as soon as you open it, with almost zero learning curve. It doesn't push you to complete tasks quickly, but first makes the conversation itself comfortable.

Who is it for?

Users who want a conversation partner without task pressure, focus on emotional support and idea sorting, as well as those who prefer a natural and friendly conversation style and are looking for someone to talk to anytime; also include users who want to practice expression and sort out their inner thoughts.

Things to know

The conversation content may be used to improve services, so please be cautious when sharing topics involving privacy; the interface is mainly in English, which poses a certain language barrier for Chinese users. As a companion-type assistant, it cannot replace formal services such as professional psychological counseling. Please seek professional help if you suffer from severe emotional distress; when relying on AI companionship for a long time, also pay attention to whether your social needs are met. Don't just keep important things in conversations, and the memory boundary is subject to the official instructions.
