Pi
A personal AI built for supportive, thoughtful conversation
About Pi
Pi is a personal AI assistant created by Inflection AI, co-founded by Mustafa Suleyman, one of the original co-founders of DeepMind. Unlike productivity-focused AI assistants, Pi is built around the idea of personal connection — it is designed to be curious, warm, and emotionally attuned, engaging users in meaningful conversations about their thoughts, challenges, goals, and daily experiences. Pi remembers details from past conversations, enabling it to build a sense of continuity and familiarity over time that most AI assistants lack. It is available via web browser and mobile app, and can also be accessed via voice for a more natural, conversational experience. Pi does not attempt to complete complex technical tasks or write code — its value lies in its quality of conversation, its reflective questioning style, and its ability to help users think through problems in a low-pressure, supportive environment.
