Pi
FreeSupportive personal AI for thinking, learning, planning, reminders, and voice conversations
About
Pi is Inflection's personal AI assistant, designed for natural, supportive conversations rather than a large set of expert controls. It can help users think through decisions, learn about a topic, brainstorm, plan next steps, create reminders and to-dos, and have voice conversations on the web and mobile apps. Pi also supports user-controlled memory, chat sharing and export, translation, notifications, and access through Apple Messages. Official help materials say Pi runs on Inflection-2 by default and does not let users choose between models. Pi can make mistakes, so verify important information and do not treat it as a substitute for professional advice.
✨ Key Features

- Planning and to-dos — Turn a conversation into next steps, reminders, and personal to-do items.
- Voice conversations — Use the microphone and speaker on the web, iOS, and Android for spoken conversations.
- Personal memory — Pi can remember user-approved facts such as preferences, goals, routines, and communication preferences.

💳 Pricing
- Free — Pi is presented as a free personal AI service on the official consumer site. Current official materials reviewed for this draft do not publish a paid subscription or a reliable paid plan matrix.
Do not describe Pi as freemium or assign a monthly price without a current official pricing source. Availability, limits, account requirements, supported channels, and data controls may vary by platform. Review the current privacy and terms pages before using Pi for sensitive personal information.
