Google expanded Gemini's Personal Intelligence so it can build custom travel itineraries by connecting the dots across a user's Gmail, Google Photos, Search, and YouTube history. Users ask Gemini to combine their dream destinations, favorite activities, and past reservations into a personalized travel plan. Connected apps and personalization settings remain user-controlled.

Google expanded Gemini's Personal Intelligence capability so that the assistant can build a travel itinerary fully customized to the user. Personal Intelligence connects the dots across the user's Gmail, Google Photos, Search, and YouTube history, then uses those signals to draft trip plans, rather than relying only on a blank prompt.

In practice, a user asks Gemini to combine their dream destinations, favorite activities, and past reservations into what Google describes as a one-of-a-kind brainstorm for future travel. The system reuses the same Personal Intelligence layer Google has been rolling out across other use cases like photo reimagining inside Gemini and the Gemini project home.

You control which Google apps Personal Intelligence connects to and can manage personalization settings at any time. The feature is rolling out to eligible Gemini users. Once enabled, the travel itinerary use case works directly inside the existing Gemini app — no separate product or signup required.

Still wondering? A few quick answers below.

Personal Intelligence is a Gemini capability that connects the dots across the user's Google apps — Gmail, Photos, Search, and YouTube — and their chat history preferences, then uses those signals to give responses tailored to that user. Google positions it as moving Gemini's answers from generic to personally relevant for tasks like trip planning and idea generation.

When a user asks Gemini to plan a trip, Personal Intelligence pulls signals from connected Google apps: reservations and confirmations in Gmail, visual interests from Photos, queries from Search, and watch interests from YouTube. Google's tweet frames the output as a one-of-a-kind brainstorm for future travel, combining the user's dream destinations, favorite activities, and past reservations.

Google specifically names Gmail, Google Photos, Google Search, and YouTube as the connected sources for Personal Intelligence in this announcement. Connections are user-controlled — the user chooses which apps to link and can manage personalization settings within the Gemini app at any time. No app is connected automatically without explicit user choice.

Personalization is managed inside the Gemini app's personalization settings. From there the user chooses which Google apps Personal Intelligence is allowed to draw from. Connections can be added or removed at any time. Google's announcement explicitly highlights this user control as part of the Personal Intelligence design.

The travel itinerary capability is part of Gemini's Personal Intelligence layer, which is rolling out to eligible Gemini users. Once a user has Personal Intelligence enabled and the relevant Google apps connected, they can ask Gemini to build a travel itinerary the same way they would any other Gemini request, without needing a separate product.
