Pi
by Inflection AI
Pi is a conversational AI assistant created by Inflection AI and designed for personal, supportive dialogue across web and mobile interfaces. Its future became less certain after Inflection shifted toward enterprise AI in 2024.
Why Abandoned
Pi's website remains reachable, but Inflection AI pivoted toward enterprise AI after Microsoft hired much of its leadership and team in March 2024. Inflection said Pi would continue at that time; its current long-term product commitment is unclear.
