What Pi AI is

Pi is a conversational assistant from Inflection AI, built around supportive dialogue rather than task automation. It asks follow-up questions, remembers what you have discussed and keeps a calmer tone than most assistants, which is why it is often used for thinking through decisions rather than producing artefacts. The interface is deliberately simple: a chat with voice input on mobile. The limits are capability and positioning: it is weaker than frontier models at coding, long documents and complex research, it does not integrate deeply with other tools, and the company has shifted focus toward enterprise since launch, so consumer features and limits have changed. For output-heavy work, a general assistant is the better choice. Typing is optional on mobile, since the voice mode handles the conversation hands-free. It is deliberately not a tool for generating documents, which is why it feels different from a work assistant.

Pricing in detail

The assistant is free to use on web and mobile, with usage limits that apply during busy periods. There is no published per-seat consumer plan comparable to other assistants, and the company focus has moved toward enterprise deployments. Because consumer terms have changed before, confirm the current limits in the app rather than relying on older descriptions.
