Pi by Inflection AI is a personal artificial intelligence assistant built around a foundation model that emphasizes emotional intelligence (EQ) alongside raw cognitive ability (IQ). Designed for individuals seeking a conversational AI that feels more like a thoughtful conversation partner than a transactional chatbot, Pi is available as a free web application and native mobile apps for iOS and Android.
How It Works
Pi is powered by Inflection AI's proprietary large language model, which was trained to excel at both helpful task completion and empathetic, supportive dialogue. Users interact with Pi through a chat interface on the web or mobile apps, typing or speaking naturally. The assistant maintains conversational context across sessions and can engage on a wide range of topics — from career advice and productivity tips to casual conversation and learning. Pi also offers a "Word of the Day" feature and supports voice input and output across all platforms, making it accessible hands-free.
Key Capabilities
Pi offers several core capabilities that distinguish it in the personal AI space. Voice conversations are supported end-to-end on web, iOS, and Android, allowing users to speak naturally and hear Pi respond. The assistant adapts to each user's preferred name and language, and supports multiple languages for both input and output. Users can upload images for Pi to analyze within conversations, and Pi can generate images upon request. The platform enables full chat history export in a documented, plain-text searchable JSON format — making Pi one of the first major AI assistants to offer comprehensive data portability through its collaboration with the Data Transfer Initiative (DTI).
Platforms & Availability
Pi is available as a web application at pi.ai, with dedicated native apps for iOS and Android available through their respective app stores. The experience is synchronized across devices so users can pick up conversations wherever they left off. Notifications are supported to alert users when Pi has a response ready, though frequency can be customized in settings. A developer API is also available through the Inflection AI Developer Portal, enabling third-party integration with Pi's underlying model capabilities.
Privacy & Data Control
Inflection AI operates as a public benefit corporation and has made user data portability a core product principle. In partnership with the Data Transfer Initiative (DTI), Pi allows users to export their complete conversation history in an open, documented format with secure digital signatures. This exported data can be archived, transferred to another LLM service, or imported into Inflection AI's enterprise product. Users can also delete their account and associated data at any time through the app settings.
Enterprise Offering
In addition to the consumer product, Inflection AI offers Inflection for Enterprise — a bespoke AI system built around the same foundational model, fine-tuned to individual business needs. Built in partnership with Intel on AI hardware, the enterprise system provides companies with owned, secure, and customizable AI deployments at a reduced total cost of ownership compared to cloud-based alternatives. The enterprise product brings Pi's emotionally intelligent approach to workplace AI, aiming to help teams become more empathetic and effective collaborators.
