Pi, created by Inflection AI, is a conversational AI positioned as a "personal intelligence partner" rather than a productivity tool. It focuses on emotionally supportive, natural dialogue, helping users vent, think out loud, prepare for hard conversations, or simply chat about topics like science and culture. Beyond conversation, Pi handles daily-life tasks such as setting reminders and to-dos, and supports voice-based interaction so users can talk instead of type. It's available as a web app at hey.pi.ai plus iOS and Android apps, built by Inflection AI, a public benefit corporation focused on human-centered AI.
Pieces is an AI-powered productivity tool that runs locally on your computer, passively capturing research, chats, notes, and meetings into a searchable timeline. Instead of manually saving snippets or notes, Pieces builds context automatically in the background and lets users query their own recent activity by time, topic, person, or tool. It integrates with over 30 applications including Gmail, Slack, VS Code, Claude, and GitHub Copilot, and can generate instant summaries like standup updates, meeting prep notes, and day recaps. Data is stored on-device by default with granular controls to pause or delete captures, and it supports the Model Context Protocol for use with AI coding assistants.
