Google kicked off 2026 with the addition of Personal Intelligence to Gemini, allowing its AI to pull in more of your data to formulate answers. It started as a paid feature but eventually came to all Gemini users. However, this feature wasn't available in the car until now. Google is rolling out Personal Intelligence to Android Auto and Google Built-in, and it is still, thankfully, an optional feature.
As Google points out, a generative AI's outputs are better "when it knows the world and knows you," which is correct in an uncomfortable sort of way. The more context you can provide to a model, the better the output will be at the end of the token shuffle. Since Google has so much of your data already, it sees Personal Intelligence as a differentiator versus other AI systems. You don't have to provide the AI context because it already has it from apps like Gmail and Calendar.
Personal Intelligence is beginning its rollout in Android Auto today, and it will come to vehicles with Google built-in in the next few months. As an aside, "Google built-in" is questionable branding, but it refers to cars that run Google software in the infotainment system rather than projecting an interface from your phone. Very few vehicles have Google built-in, but Google often releases new car features on them first. This time, it's the other way around.
