Prepare at home
Download a suitable model over a reliable connection and try a short conversation before leaving. Check that it works without a connection, and leave enough storage and battery for your journey.
Start with a few details
Try: “Make a warm postcard from these notes: rainy morning, good coffee, long walk.” Tell the AI who you are writing to and the tone you want.
Keep the story yours
Use an answer as a draft, not a record of what happened. Remove invented details and change the wording until it sounds like you.
Check current information at the source
Train delays, opening hours and entry rules can change. Check the transport operator or official authority rather than relying on an offline answer.
Keep travel essentials within reach
Save tickets, maps, bookings and emergency numbers separately. Keep original documents too: a conversation backup does not include your source files or photos.
