AI assistant by Anthropic with advanced reasoning and long context windows

Pi (Personal Intelligence) represents a different approach to AI assistants. Rather than focusing purely on productivity or information retrieval, Pi is designed to be a supportive conversational partner that listens, asks thoughtful questions, and provides emotionally intelligent responses. Created by Inflection AI (founded by LinkedIn co-founder Reid Hoffman and DeepMind co-founder Mustafa Suleyman), Pi uses advanced language models trained specifically for natural, empathetic conversation. The AI adapts its communication style based on user preferences and maintains context across conversations. Pi excels at helping users think through problems, process emotions, brainstorm ideas, or simply have interesting discussions. Unlike task-focused AI assistants, Pi prioritizes the quality of conversation and the user's wellbeing. The platform is available through web, iOS, and Android apps, and even offers voice conversation capabilities. Pi has gained a loyal following among users who appreciate having a non-judgmental AI companion for daily check-ins, creative thinking, or working through challenges. Recent updates have improved Pi's memory capabilities and expanded language support.
