Poke is a proactive AI personal assistant that operates through messaging apps including Apple Messages, WhatsApp, and Telegram. It integrates with third-party services like Gmail, Notion, and Oura to help users manage tasks, emails, schedules, and health data via text. Poke learns user preferences over time and proactively surfaces relevant information without being prompted. Developers can extend its capabilities by building custom integrations through the Poke Kitchen recipe system.
