Three weeks out, the seating chart is done, the cake is paid for, and there’s still a blank document titled “vows.docx” that you open, stare at, and close. Writing what you feel about the person you’re marrying — in a way you can read out loud without crying or cringing — is genuinely hard, and a lot of people have quietly opened ChatGPT to break the logjam. Same goes for the best man who’s realized the toast is in four days.
It can help. But wedding words are the one place where “let AI write it” can backfire badly — sometimes embarrassingly, and in one real case, legally. So here’s how to use it to beat the blank page without handing over the part that makes it mean something.
First, the cautionary tale that’s all over TikTok
In early 2026, a court in Zwolle, the Netherlands, ruled that a couple wasn’t actually, legally married. A friend acting as their one-day registrar had used ChatGPT to write a warmer, more personal ceremony — lovely lines about laughing together, growing together, “a crazy couple.” The problem: the AI script left out the specific declaration Dutch law requires for a marriage to be valid (Article 1:67 of the Civil Code — the formal “I accept you as my spouse and will fulfil the duties the law connects to marriage”). Because that exact wording was never said, the court found no marriage had been established. The couple had a beautiful ceremony and no legal marriage.
That’s the extreme version of the real risk. The everyday version is quieter: AI writes something fluent and completely generic, you read it at the altar, and three guests afterward ask if you used ChatGPT. The fix for both is the same.
The 5 prompts that keep your voice
The whole method rests on one idea: you supply the truth, ChatGPT shapes it. It should never be making up how you feel — it should be organizing what you tell it.
Prompt 1: Make it interview you
Don’t ask for vows. Ask it to ask you:
I'm writing my wedding vows. Before you write anything, interview me — ask me
the questions that will surface the specific stories, moments, inside jokes,
and promises that make good vows. Ask a few at a time and wait for my answers.
Answer in messy, honest sentences. The day you got caught in the rain, the thing they do that drives you crazy and that you’d miss instantly. This is the raw material no AI can invent.
Prompt 2: Draft from your answers only
Now write a first draft of my vows using only what I told you. Keep my voice —
plain and warm, not flowery. About 90 seconds spoken. Build it around the real
stories, not generic "you're my best friend" lines.
Prompt 3: Strip the clichés
Cut every line that could appear in anyone's vows. If a sentence would work for
a stranger's wedding, replace it with something only I would say.
This single prompt is what separates vows that sound like you from vows that sound like a greeting card.
Prompt 4: The read-aloud pass
Read it back formatted for speaking — short lines, natural pauses, nothing I'll
trip over. Flag any phrase that's hard to say out loud or might make me choke up
mid-sentence.
Prompt 5: The validity check (do not skip this)
What does my officiant or venue require me to actually say for the ceremony to
be valid or complete? List the questions I should ask them before finalizing.
ChatGPT can’t know your jurisdiction’s rules — but it’s good at reminding you to ask. Then you confirm the required wording with your officiant, not the chatbot. That’s the step the Dutch couple’s registrar skipped.
The best-man / maid-of-honor version
Same method, different shape. Have it interview you for the story — the one that captures your friend — then ask for a structure: open, the story, the heartfelt turn, the toast. Two extra rules for speeches: tell it to keep it under four minutes spoken, and never include a joke you can’t personally vouch for. The AI doesn’t know which inside jokes land and which one gets you a death stare from the head table.
What this means for you
- If you’re writing your own vows: use it to get unstuck and to cut clichés, never to manufacture feeling. The vows people remember are specific and a little imperfect — feed it your real stories and protect them through every edit.
- If you’re the best man or maid of honor: this is a lifesaver for structure and nerves. Just verify every joke and keep it short — the speech that kills is the one that’s clearly about this person.
- If you’re not a “words person”: this is genuinely what AI is best for — you clearly feel it, you just can’t shape it. Let it organize what you tell it, then read it out loud until it sounds like your mouth, not a script.
- If a friend is officiating: this is the one with legal stakes. Have them confirm the exact required wording with the venue or local registrar before the day. A heartfelt ceremony that skips the legal line is the one viral story you don’t want to star in.
What ChatGPT can’t do here
- It can’t feel anything. It produces fluent, plausible emotion — which reads as hollow precisely when it matters most. The realness has to come from you.
- It can’t know the legal requirements. Marriage validity rules are local and specific. It will happily write vows that aren’t legally sufficient. Confirm with a human.
- It can’t keep your secrets out. Don’t paste anything you wouldn’t want logged. Sharing “the story of how we met” is fine; sharing private details about other people is not.
- It can’t make it sound like you on the first try. The default voice is everyone’s voice. The cliché-cutting and read-aloud passes are not optional — they’re where the personality goes back in.
The bottom line
ChatGPT is a great cure for the blank page and a terrible ghostwriter for your heart. Let it interview you, draft only from your real stories, cut every line a stranger could say, and confirm any required wording with your officiant — and you’ll stand up with something that’s unmistakably yours, just finished on time. The couple in Zwolle didn’t lose their marriage because they used AI. They lost it because nobody checked what actually had to be said.
