Outcome

Planning a destination wedding in Sesimbra, Portugal, and getting the same questions from guests despite a detailed website, a bride built a custom GPT as a travel assistant: she pasted in the private wedding website content and told it to act as a friendly travel agent answering about venues, travel tips and dress code. She says it took under 5 minutes to set up and saves her time; custom GPTs need a paid account.

Prompt Recreated prompt

The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I know, you suggest options and ask what you need, and we'll narrow it down step by step. Nothing gets booked, bought or sent until I say so.

Goal: Let's set up an assistant that answers guests' questions about my event using only my event details.

What I'll share as we go:
- All event details (venue, dates, travel, dress code, schedule)
- Tone I want
- Questions guests ask most

Rules:
- Answer only from the details I give; say 'please ask the hosts' when unsure.
- Keep answers short and friendly.
- Point to official sites for flights, visas and transport.
- Never share private details I mark as private.
- If a site asks for a login, a CAPTCHA or payment details, stop and hand control back to me.
- Ask for my OK before you pay, book, send, submit or cancel anything.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: Assistant instructions plus a test of 5 common guest questions.

You'll know it worked when: it answers the common questions correctly and says when it doesn't know.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

    A few months before his wedding, TechRadar's Hamish Hector tested Bridebook's ChatGPT integration with the venue brief he and his fiancée had used. Several venue costs were wrong compared with quotes they'd received, and he found it no more useful than scrolling Bridebook or Google, in some ways less, because its results were more restrictive.

    Hosting a family reunion for 55+ relatives from around the world, an organiser used Claude to clean a messy master roster, get vendor headcounts, send individual reminder emails, reconcile costs, produce individual schedules and roll-call sheets, and flag food allergies by meal. It also laid out the event program, cooler signs, mingling Bingo cards and colour-coded name tags on a specific Avery template. Earlier she'd used ChatGPT for the schedule, a local guide and newsletters.

  • Gemini vs ChatGPT on a check-engine EVAP code: replace the sensor or clear the code?Recreated promptEvidence: Described by poster

    After a check-engine light on his pickup, a driver read one evaporative-system code and the sensor readings, then asked Gemini and ChatGPT what they meant. Gemini suggested replacing the sensor; ChatGPT said to clear the codes and see if they came back. He cleared them, and after a long trip the code hadn't returned, avoiding a costly, labour-heavy part replacement for now.
