Pi

Pi, from Inflection AI, is a personal AI assistant designed around warmth, empathy, and natural conversation rather than productivity, making it a go-to for emotional support, reflection, and friendly advice. After Inflection pivoted toward enterprise in 2024-2025 and dropped Pi support on third-party messaging apps in early 2026, Pi continues operating via its own apps and website, still serving millions as a companion. It remains the standout chatbot for users who value a kind, supportive conversational tone over raw task performance.

Key features

• Empathetic, conversation-first design
• Natural voice conversations
• Emotional support and reflective dialogue
• Available on web, iOS, and Android
• Remembers context across conversations
