I Let AI Write My Wedding Vows — Here's What Happened

 Writing your wedding vows is the hardest two minutes of writing you will ever do. It has to be romantic but not cheesy, personal but not embarrassing, and short enough that nobody starts checking their phone. So I did what any sensible person in 2026 would do: I handed the job to AI and waited to see if it could write something I would actually say out loud.

The Setup: Four AI Tools, One Impossible Job

I gave four tools the same brief: write two-minute vows for a wedding, warm and funny, built around a real story — how we met at a friend's rooftop party, the terrible first date at a noisy taco place, and the moment I knew, on a rainy drive home. ChatGPT (free tier, Plus is $20 a month) got the most detailed prompt. Joy, the free wedding platform, has an AI feature called Writer's Block that drafts vows and toasts — it even offers tones like Shakespeare, pirate, therapist and TikToker. Provenance, which builds ceremony scripts, has a free ceremony-builder tier. And Vows.you is a free vow tool that needs no login at all, with cliche detection and a practice teleprompter

What the AI Actually Wrote

The first drafts were... fine. Polished, even. And completely interchangeable with anyone else's vows. ChatGPT gave me "you are my best friend, my greatest adventure, my home" — a sentence that has probably been read at ten thousand weddings. Joy's Shakespeare tone was genuinely funny and completely unusable unless I wanted my guests to think I had time-travelled. Provenance had the best structure: a clear opening, a story beat, then the promises. Vows.you did something clever — it flagged the cliches in my draft and timed how long it would take to read aloud, which kept me inside the one-to-two-minute sweet spot. Every tool produced something readable. None of them produced something that sounded like me.

The Fix: Feeding It Real Memories

The turning point was the prompt, not the tool. When I stopped asking for "romantic wedding vows" and started feeding it specifics — the taco place, the rain, the exact joke from our first date — the drafts changed completely. ChatGPT rewrote the same vows around those details and suddenly they sounded like our story, not a greeting card. My rule became simple: the AI gets the facts, I keep the feelings. Anything it wrote that I would not actually say out loud got cut, no matter how pretty it sounded. I read every version aloud, twice, because vows are spoken, not read — a line that looks beautiful on screen can fall flat in your mouth.

The Verdict: Brilliant First Draft, Terrible Final Author

Here is the honest result. AI is a brilliant first-draft machine and a terrible final author. The vows I would actually use ended up about 70 percent mine and 30 percent AI scaffolding — its structure, my stories, my words. If you are staring at a blank page, start with Provenance for the structure, let ChatGPT rewrite around your real memories, and run the result through Vows.you to kill the cliches and check the timing. And never, ever send an AI draft untouched — your partner will know, your guests will know, and honestly, you will know. It is the same lesson I learned letting AI plan my honeymoon — the tool does the heavy lifting, but the memories have to be yours. The best wedding vows are not the most poetic ones. They are the ones only you could have written — and AI, used properly, just helps you get there faster.
