Every AI writing tool will happily write a wedding toast. What it cannot do is know the story — the night your friend fell asleep at the shared Airbnb, the way the couple argue about dish duty. That is the whole speech. So the useful division is: let the tool do the scaffolding, you do the memory.
What it is genuinely good at
- Structure. Three beats: where you met, what changed, what you wish for. Every good toast follows one of these.
- Timing. Feed it your own words and ask for a 90-second version. You cannot self-edit from the inside; it can count.
- Tone checks. Ask it to make the same paragraph funnier, softer, or shorter. You pick, it rewrites.
- Vow language. Sample clauses you would otherwise never phrase — the commitment parts that are hard to start.
- The less emotional documents. Table cards, order of service, thank-you notes to the venue team.
Where it falls flat
- In-jokes. It has never been to that wedding. A "private joke" it invents lands silently in front of 120 people.
- Accurate detail. Dates, places, the name of the dog. Check every one.
- Anything a relative will recognise. A model will write a touching line that is factually wrong about someone in the room.
- Vows that sound got from the internet. Guests have heard them. The online vow template is the single most noticeable thing at a wedding.
Our honest workflow
Write your raw material badly and in order — five minutes of voice notes, no editing. Paste that in and ask for a structure with markers for where your story goes. Fill the markers with the real anecdotes. Then ask it to cut to 90 seconds. Practise it standing up; if you run over, the version you cut is what you read.
On editing time: our 30-day benchmark measured about 22 minutes of editing per 1,000 words on the cheap dedicated writer versus 8 minutes on the premium one. For a one-off speech that math does not matter. What matters is that you only get one go at this, and no model has ever been to your wedding.
One rule
Read it out loud to one person who was there. If they laugh in the right place, it is a speech. If they ask "wait, is that true?" — fix the fact, and the speech gets better on its own.
What people ask
Can AI write my wedding vows?
It can draft the shape and offer phrasings you would not reach for. Every specific memory should be one you actually lived.
Is it awkward to use AI for a best-man speech?
No, guests have never once thought about how the words were drafted. They notice only whether it was funny and whether you looked nervous.
How long should the speech be?
90 seconds is about 200 words of real content. If a model hands you 900, cut it — that is what it does badly and you do well.
Frequently Asked Questions
Can AI write wedding vows?
It drafts structure and phrasing. The memories and promises must be yours — guests recognise templated vows instantly.
How do I stop my speech sounding generic?
Include one verifiable, slightly embarrassing, true detail. Specificity is the only thing that reads as a real speech.
Is it worth paying for a tool for one speech?
Not for the speech itself. Only if you also write the thank-you notes, table cards and venue copy around it.
