Pi
Pi is the personal AI chatbot developed by Inflection AI, designed to offer a conversational experience that blends emotional intelligence with practical knowledge. Rather than just answering queries, Pi aims to act as a supportive companion—engaging users in dialogue, reflecting their emotional tone, and providing advice, brainstorming, or simply a friendly conversation.
Under the hood, Pi runs on Inflection’s custom language models (such as the “Inflection‑2.5” upgrade), which the company claims deliver high performance in reasoning, math, and general tasks while using less compute than some peers. Users can export their conversation history to retain ownership of their data, and Pi is available across web and mobile platforms. While its tone emphasizes empathy and moderation, Pi isn’t immune to occasional factual errors or conversational quirks that come with generative AI.
