Plan a surprise on the family computer without spoiling it
The plan hides from your chat list and search, and it opens only with your PIN or Face ID.

How do I keep a ChatGPT chat private on a shared computer?
Lock the chat. Open the chat's three-dot menu and select Lock chat, then open it later with your 4-digit PIN or Face ID (as of October 2026). It's the right pick when you want to keep the plan and come back to it. If you only need a one-off answer you never want saved, a temporary chat fits better. Locking hides the chat from history and search, but it isn't encryption, so treat it as privacy from people nearby.

Your prompt

ChatGPT opens with your prompt already typed in. It's copied too, just in case.
The prompt that gets copied
I'm planning a surprise for [THE OCCASION, e.g. my wife's 50th birthday] on [THE DATE, e.g. Saturday, March 14]. My budget is [YOUR BUDGET, e.g. about $600] and the people involved are [YOUR HELPERS, e.g. our two kids and her sister]. Things they love: [WHAT THEY LOVE, e.g. jazz, Italian food, the beach] Things to avoid: [THINGS TO AVOID, e.g. big crowds, being on stage] Please give me: 1. Three surprise ideas that fit the budget, each with a one-line reason it suits them. 2. For the idea I pick, a countdown checklist from today to the day. 3. A cover story I can use if they ask what I'm up to. 4. Short, friendly messages I can send to each helper with their job. Keep it realistic and easy to pull off. Ask me which idea I want before you build the checklist.
Plan a birthday, anniversary or proposal surprise in a ChatGPT chat you lock with a PIN, so nobody sharing your laptop or phone stumbles on it in your history.
