Pi
Inflection AI's conversational assistant designed for empathetic, supportive dialogue.
Definition
Pi is a conversational AI assistant developed by Inflection AI, designed with an emphasis on empathetic, emotionally supportive dialogue rather than purely task-focused responses. It positions itself as a personal companion and is accessible across web, mobile, and messaging platforms. Its ownership and development direction shifted after much of Inflection's team moved to Microsoft, so its current status is worth verifying before publishing.
