Google has introduced "Personal Intelligence" for Gemini. This new feature gives Google's Gemini AI tool access to your emails in Gmail and/or your photos in Google Photo to deliver more personalized results. This strictly opt-in (for now) feature can also link YouTube and Google Search, and works across platforms. Personal Intelligence doesn't let Google train its AI model on your personal data; instead it lets a pre-trained model access your data upon request. Personal Intelligence can be turned off at any time, and you can choose which apps to connect. It will explain where it sourced data for personalized results so you can verify yourself. It also has "guardrails" for sensitive topics like health.
