The short version: ChatGPT won't book your venue or turn up on the day, but it will do the thinking work that eats your evenings: building a budget, drafting vendor emails, working out a guest list and writing a timeline. Below are prompts you can copy, paste and edit for your own wedding, grouped by the stage you're at.
I've written these the way I'd use them myself: specific enough to get a useful answer first go, with the bits you need to fill in marked in square brackets. Swap those out, run the prompt, then treat the answer as a first draft you tighten up, not a finished plan.
Setting your budget and working out priorities
Most wedding budgets fall apart because nobody wrote down what really matters to the couple before the quotes started coming in. Start here before you contact a single supplier.
I'm planning a wedding for [number] guests with a total budget of [amount]. Break this budget down into typical percentages for venue, catering, photography, attire, flowers, music and everything else, then flag which categories usually go over budget so I know where to build in a buffer.
Here are the three things that matter most to us for our wedding: [list your top three, e.g. good food, great photos, a live band]. Suggest where we could spend less on everything else without the day feeling cheap, given those priorities.
We have [amount] left after booking the venue and catering. List the remaining wedding costs we're likely to forget about, such as [alterations, postage, marriage licence, hair and makeup trials], with a rough UK cost range for each.
Finding and negotiating with vendors
This is where ChatGPT earns its keep. It can draft the awkward emails so you're not starting from a blank page every time you need to chase a florist.
Write a polite email to a wedding venue asking whether they offer a discount for a [day of the week, e.g. Friday or Sunday] wedding, or for booking more than [number] months in advance. Keep it warm but direct and ask for their current availability for [month/year].
I've had a quote of [amount] from a [type of supplier, e.g. photographer] for [package details]. Write a reply asking if they have a smaller package or a way to bring the price closer to [your budget], without sounding like I'm trying to get something for nothing.
Write a list of ten questions to ask a wedding caterer before booking them, covering dietary requirements, staffing, corkage, and what happens if guest numbers change closer to the day.
Guest list and invitations
The guest list is where budgets quietly balloon. A clear cut off line, decided early, saves a lot of awkward conversations later.
We want to keep our wedding to [number] guests and a budget of [amount] per head. Suggest a fair way to decide who makes the final cut when we're currently at [current number] names, including how to handle plus ones and children.
Write wording for a wedding invitation for a [formal/casual] wedding at [venue] on [date], including a line asking guests to RSVP by [date] and a polite way to mention there's no space for children under [age].
Building the timeline for the day
A tight, realistic timeline stops the day running late and costing you extra in venue overtime or vendor fees.
Build a wedding day timeline starting from [ceremony time] at [venue], including hair and makeup, travel time, photos, the ceremony, drinks reception, speeches, meal and first dance, finishing by [time]. Flag anywhere the schedule looks too tight.
We have a [number]-minute gap between the ceremony and the wedding breakfast while photos are taken. Suggest three ways to keep guests entertained during that gap that don't cost extra.
Write a rehearsal dinner run sheet for [number] people the night before the wedding, keeping it to two hours including welcome drinks, food and a short toast.
Cutting costs without it looking cut price
This is the section that saves the most money. Ask ChatGPT to think like someone who's planned a lot of weddings on a tight budget, not someone reaching for the most expensive option first.
Suggest ten ways to reduce the cost of wedding flowers by at least [percentage or amount] without the arrangements looking sparse, including which flowers are usually cheaper in [month] in the UK.
We want a full bar for [number] guests for [number] hours but our drinks budget is [amount]. Suggest a drinks menu that keeps costs down without it feeling like a cash bar, including how to word a sign for guests.
List realistic ways to cut catering costs for a [number]-guest wedding, comparing a sit down meal, a buffet, food stations and grazing tables on rough cost per head in the UK.
DIY touches that don't eat your weekends
DIY only saves money if it doesn't cost you three weekends and a trip to the emergency room with a glue gun burn. Ask for the ones that are really worth doing yourself.
Suggest five wedding DIY projects that are truly quick to make (under two hours each), save real money compared to buying them, and won't look homemade in photos, for a [style, e.g. rustic/minimalist] wedding.
Write step by step instructions for making our own wedding favours using [materials you already have or want to use], for [number] guests, including a rough cost per favour.
Handling stress and family opinions
Budget weddings come with their own particular stress: the relative with strong opinions and no budget of their own. A neutral third party helps you find the words.
Write a kind but firm message to a family member who keeps suggesting expensive additions to our wedding that we can't afford, without starting a family argument.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
We're feeling overwhelmed with [number] weeks left until the wedding and still have [list what's left to do]. Turn this into a prioritised to do list by week, with the most urgent and hardest to change items first.
Getting better answers out of every prompt
The quality of what you get back depends almost entirely on how much detail you put in. A prompt that just says "help me plan my wedding" gets a vague, generic answer that could apply to anyone. A prompt with a real guest number, a real budget, a real month and a real style gets something you can use straight away.
It also helps to treat the first answer as a starting point rather than the finished thing. If a suggestion doesn't fit your venue, your family, or your taste, say so and ask for another version. Something like "that's too formal for us, can you make it warmer and less scripted" gets you a far better second draft than starting again from scratch. Think of it as a conversation with a very quick, very patient planning assistant rather than a vending machine that only gives one answer per question.
One more thing worth doing: save the good answers somewhere outside the chat, in a document or a notes app, as you go. Wedding planning stretches over months, and chat histories get long and hard to search. A simple running document with your budget breakdown, your vendor emails and your timeline in one place will save you more time than any single prompt.
Finally, don't be afraid to ask for the blunt version. A prompt like "tell me honestly if this budget is realistic for what we want" tends to get a more useful answer than one that only asks for positive suggestions. Planning a wedding on a budget means making trade offs, and it helps to know where the real pressure points are before you've signed a single contract.

Frequently asked questions
Is it safe to put personal details into ChatGPT while planning a wedding?
Keep names, addresses and payment details out of your prompts. Use placeholders like "the venue" or "our supplier" instead of real names if you're worried about privacy, and never paste in anything from a contract that includes bank details.
Can ChatGPT really book anything for us?
No. It can draft the email, but you still need to send it, make the call or fill in the form yourself. Think of it as a very fast, very patient assistant who writes brilliant first drafts and does none of the admin.
Will these prompts work for a wedding outside the UK?
Yes, just swap the currency and add your country when you ask about costs, since prices and typical customs (like corkage or service charges) vary a lot by country.
How do I get a better answer if the first one feels generic?
Add more detail. Instead of "our wedding", say the guest number, the month, the style and the budget. The more specific the prompt, the less generic the answer.
Wedding planning on a budget is mostly about decisions made early and stuck to. Use these prompts to get the boring parts (the emails, the spreadsheets, the timelines) off your plate fast, so you've got more time and energy left for the parts that really feel like planning a wedding.
