Personal AI is shifting from single-session answers to durable context. OpenAI says the new ChatGPT memory starts with US Plus and Pro users and uses a more efficient architecture that reduced compute needs by about 5x.
Google said on March 17, 2026 that Personal Intelligence is expanding in the U.S. across AI Mode in Search, the Gemini app, and Gemini in Chrome. The feature connects services like Gmail and Google Photos so Google can answer with more user-specific shopping, travel, and troubleshooting help, and Google says it is available to free-tier users.
