About Pi

Pi is a personal AI built by Inflection AI, designed for conversation rather than task completion. It's useful for working through decisions, talking through problems, or just having an engaged back-and-forth. It asks follow-up questions, remembers what you've shared across sessions, and maintains a consistently calm, unhurried tone. The underlying models (Pi-3.1 family) are trained in-house by Inflection. Pi is available on web, iOS, Android, Mac, Windows, WhatsApp, Discord, Telegram, and SMS. Voice mode offers eight voice options with natural-sounding inflection. Core access is free with no usage limits, though rate limits were introduced in 2024 to manage infrastructure costs. Conversations are private by default and not used to train models without your consent. Enterprise licensing is available for custom deployments.

Pricing

Completely free. No subscription tiers, premium features, or usage-based pricing. Rate limits may apply to prevent abuse of free resources.
