otsuka vs ChatGPT
ChatGPT is good for researching a trip and drafting a plan. otsuka turns the plan into days with times on your phone, and changes them with one tap when the day changes, with undo.

| Changing the plan | One tap for rain, one for a tired day, one to move a thing. Each says where everything lands, and can be undone. | You ask again, and it writes the reply again. |
| On the day | Opens on today: what's on now, what's next, the rest below. | The same chat |

Where ChatGPT is better
- It answers anything: visas, packing, what a dish is, the history of a place.
- Any destination and any kind of trip.
- It's free, or already part of what you pay for.
Where otsuka is different
- The plan is a schedule that lives on your phone, not a message in a conversation.
- Changes follow fixed rules: meals stay, the things you came for stay, nothing lands on top of something else, and every change can be undone.
- Travel mode: today, one thing at a time.
- otsuka's first plan is written by AI too, so check the places that matter before you go.
