Writing vows is the part of the wedding almost everyone dreads. You are staring at a blank page, trying to sum up years of love in two minutes, with an audience in mind. So it is no surprise that more couples are asking whether a chatbot can help. The honest answer: yes, as a sparring partner. No, as a ghostwriter. And there is one legal wrinkle every couple should know about before the big day.
Why couples are turning to AI for vows
Vow-writing is hard because it is personal. You want it to sound like you, but you also don't want to ramble, cry through paragraph three, or accidentally say something that only makes sense to you. AI tools promise a quick first draft, and a Los Angeles event planner told Fox News that many of her couples put their main ideas into ChatGPT and use the result as a starting point. Marriage-focused voices have been cautious: Focus on the Family's Greg Smalley said using AI to get ideas for what to say is fine, but warned against copying it word for word.
That framing is the useful one. AI can unstick you. It cannot know the way your partner laughs at their own jokes.
The legal wrinkle: vows are not the same as the legal declaration
Here is the story worth knowing. In early 2026, a Dutch court ruled that a couple's marriage was not valid because a legally required declaration of consent was missing from their ceremony. The couple had asked a friend to officiate as a one-day registrar, and reports said the ceremony text had been checked with or drafted by ChatGPT. Some details are disputed, including how much AI was actually involved, and the couple reportedly denied parts of the account.
The takeaway isn't "AI ruined a wedding." It's this: your personal vows and your legal marriage declaration are two different things. The legal wording, the words that actually make you married, is set by your local rules. Whether you are marrying in the US, UK or Canada, check what your officiant or registrar must say, and make sure those words are in the ceremony script exactly as required. Personal vows are the creative part you add on top.
This is a general overview, not legal advice. Your licensed officiant or local marriage office is the authority.
A sensible way to use AI for vows
If you want help, treat the tool like a writing buddy:
- Start with your own notes. Spend ten minutes jotting memories, inside jokes, small habits, and what you'll promise. Raw and messy is perfect.
- Ask for structure, not sentences. "Give me three possible outlines for a two-minute vow" beats "write my vows."
- Rewrite everything in your own voice. If you would never say the word "tapestry" out loud, cut it.
- Keep the specifics. A generic line about "always being there" is forgettable. "I'll keep pretending I like your playlist on road trips" is vows.
- Read it aloud. Time it. Two minutes is plenty.
- Keep it private until the day. Don't show your partner; the surprise is half the point.
What AI can't do
It can't remember the night you got stranded in the rain and ended up laughing anyway. It can't tell if a line sounds like you. And it can't judge whether your grandmother in the front row will be fine with a joke. Those are human calls, so make them yourself.

FAQ
Is it okay to use ChatGPT for wedding vows? There's no rule against it. Most advice is to use it for ideas and structure, then rewrite so the words are truly yours.
Can AI-written vows make a marriage invalid? Personal vows alone don't make you legally married; the required legal declaration does. In a reported Dutch case, a marriage was ruled invalid because a required declaration was missing. Confirm the wording with your officiant.
How long should wedding vows be? About one to two minutes, or roughly 200-300 words, is a comfortable range for most couples.
Should we write vows together or separately? Many couples write separately and keep them secret. Others agree on a shared length and tone so neither feels out of step.
