Can AI write my wedding toast?

Half. AI gives you a strong structure and smooth lines. The stories and feelings have to come from you, or it'll sound generic.

Their names: [NAMES]
Two or three real stories or details: [STORIES]

  1. Give it real stories.

"Ladies and gentlemen, family, and friends, welcome! My name is [Your Name], and I'm honored to stand here today as Michael's best man and longtime friend. I've known Michael for 13 incredible years, since our college days, and I've had the privilege of watching him grow into the kind, compassionate, and adventurous person he is today.

I still remember the story Michael shared with me about their senior year. After a grueling exam, he surprised Emily with a homemade pizza, and they ended up sharing a midnight study session. It was a small gesture, but it spoke volumes about Michael's thoughtful and caring nature. And, as we all know, that study session was just the beginning of their beautiful journey together.

What I admire most about Emily and Michael is the way they balance each other out. They share a sense of adventure, a love for laughter, and a deep commitment to one another. Like the time Emily organized a surprise birthday road-trip for Michael to a lake cabin, where they got lost but discovered a hidden waterfall. Or, who could forget their infamous flour fight during their first holiday together, when their cake-baking attempt ended in a hilarious mess? These moments showcase their ability to find joy in the unexpected and to laugh together, even in the most chaotic of situations.

To Emily and Michael, your love is the kind that inspires us all. You make each other better, and your bond grows stronger with each passing day. So here's to the happy couple: May your love continue to be the guiding force in your lives, and may your adventures together be filled with laughter, joy, and an endless supply of pizza. Cheers!"

The answer includes multiple stories instead of the required single story.

The made-up sample (a messier one):

  • [e.g. best friend of the groom for 12 years]College roommate and longtime confidant of the groom; we met during sophomore year and have been practically inseparable for about 13 years now, sharing everything from late‑night pizza runs to questionable career advice.
  • [NAMES]Lena Patel and Marco Silva
  • [STORIES]The night Marco tried to navigate our road‑trip to the beach using a napkin map from a coffee shop and got us hopelessly lost for two hours; the time Lena accidentally set off the fire alarm at the venue while testing the candles and we all had to evacuate the rehearsal dinner; the moment Marco showed up to Lena's birthday with a karaoke machine and sang 'Can't Help Falling in Love' off‑key but with total sincerity.
  • [e.g. warm with a few light jokes]A friendly, heartfelt tone that leans into genuine affection, sprinkled with a couple of gentle, good‑natured jokes that anyone at the wedding can appreciate without feeling left out.
  • [e.g. exes, inside jokes others won't get]Avoid any mention of past relationships, obscure college nicknames, or inside jokes that only a handful of friends would understand.
  • Use only supplied stories, no invented memories
  • Follow structure: intro, one story, what makes them great, toast line
  • Maintain friendly, heartfelt tone with gentle jokes
  • Avoid prohibited content like past relationships or obscure nicknames
  • Didn't make up details we never gave it

Here's a possible wedding toast:

"Ladies and gentlemen, family, and friends, welcome! My name is [Your Name], and I'm honored to stand here today as Marco's college roommate and longtime friend. I've had the privilege of knowing Marco for 13 incredible years, and I've seen him grow into the kind, compassionate, and slightly navigation-challenged person he is today. Speaking of which, who could forget the time Marco tried to navigate our road trip to the beach using a napkin map from a coffee shop? We got hopelessly lost for two hours, but it was worth it just to see the look of determination on his face.

As I've gotten to know Lena over the years, I've seen the way she brings out the best in Marco, and vice versa. They balance each other's quirks and strengths, and their love is the kind that makes you believe in fairy tales. Like the time Marco showed up to Lena's birthday with a karaoke machine and sang 'Can't Help Falling in Love' off-key but with total sincerity – it was cheesy, but it was also perfectly sweet.

What I love about Marco and Lena is the way they make each other laugh, the way they support each other's dreams, and the way they've built a life together that's filled with love, adventure, and a healthy dose of humor. So here's to Marco and Lena: may your love continue to be the guiding force in your lives, and may you always find your way, even when the map is a little sketchy. Cheers!"

Watch for extra story breaking the required one‑story structure.

How each run works: we fill the prompt with a made-up sample, run it once in Llama 3.3 70B, and GPT-OSS 120B grades the answer against the prompt's own rules. Word limits are counted by code, and every quote flagged as made up is checked against the full answer. Your results can differ. How we test.
