OpenAI adds Spotify, Canva, Booking to ChatGPT

OpenAI has begun integrating external apps directly into ChatGPT using the Model Context Protocol (MCP), enabling users to perform tasks like listening to music, planning trips, or designing content without leaving the chat interface. An App SDK allows developers to connect their services to ChatGPT, with initial partners including Spotify, Figma, Canva, and Booking.com and additional integrations planned from Peloton, Uber, and Tripadvisor. The features are available to all registered ChatGPT users outside the EU in Free, Go, Plus and Pro plans, while the EU rollout awaits regulatory and privacy-compliance alignment. OpenAI is also testing ChatGPT Pulse, a daily personalized update feed from chats and connected apps. App connections require explicit user consent for data sharing; an app directory is planned to surface trusted tools, and OpenAI is exploring a monetization framework for developers. This move reinforces ChatGPT as a central hub for work, travel, and personal creative tasks.
