What the alternative costsA free chat interface is enough for a first draft, and no human alternative price is supplied here.
If this goes wrong: the speech sounds generic or a joke lands badly, but you can remove the line and rewrite the draft before the wedding.
What to actually do
Do it yourself
The route this page recommends
A chat interface, no skill needed, and roughly 30 minutes until you can act on the result.
How to actually do it
- Open a blank note and write down the groom's full name, your relationship, how long you have known him, the couple's names and the target speaking time.
- Gather two or three specific stories with a clear beginning and outcome, then remove anything private, humiliating or unsuitable for the wedding guests.
- Add one sincere observation about the couple, the names of anyone who should be thanked, and a list of subjects or jokes to avoid.
- Paste the prompt into ChatGPT, Claude or Gemini and replace every bracketed slot with your own details before sending it.
- Read the generated speech aloud and delete any line that is not true, does not sound like you, or depends on an audience reference that guests will not understand.
- Compare every name, date, relationship and event in the draft against your notes, then ask the chatbot to shorten or soften any section that feels too long or too sharp.
- Send the final draft to the groom or another trusted person only if doing so will not spoil the surprise, and practise it aloud with the written toast.
Prompt
Write a best man's speech for my wedding reception using the information below. Make it sound like a real person speaking, not a formal article or an AI-generated script. Details: - My name: [your name] - Groom's name: [groom's name] - Bride or partner's name: [name] - How I know the groom and how long we have known each other: [details] - Two or three specific stories that show the groom's character: [stories] - One warm observation about the couple: [observation] - Guests who will be present and anything they will recognise: [details] - Topics, people or jokes to avoid: [details] - Desired tone: warm, funny and affectionate, without embarrassing anyone - Target speaking time: [for example, five to seven minutes] Use only the facts I provide. Do not invent achievements, events, relationships or quotations. Keep the humour kind and understandable to the whole room. Start with a short welcome, introduce my relationship with the groom, develop the best stories with clear transitions, say something sincere about the couple, thank the relevant people if appropriate, and finish with a concise toast. Mark any place where a missing detail is needed as [CHECK THIS] rather than guessing. Give me the speech first, followed by a short list of factual details and jokes I should check before reading it aloud.
Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

The distant thirdA person who owns the outcome does this end to end, worth it when the failure is dear.
What it gets wrong
- AI cannot know which private story the groom would genuinely enjoy hearing told in front of family and friends.
- It cannot reproduce your shared history or natural speaking voice from a few facts without sounding partly generic.
- It cannot reliably judge whether a joke will embarrass someone in that particular room.
- It cannot deliver the timing, eye contact, pauses and warmth that make a speech work in person.
Even on a YES, the friction has a name: taste, relationship and context depth.

FAQ
- Can ChatGPT write my best man's speech?
- Yes. It can turn your stories and notes into a structured speech with an opening, jokes, a sincere section and a toast. You still need to supply the real material and remove anything that does not sound like you.
- What should I tell AI to write a best man's speech?
- Give it specific stories, the couple's names, your relationship with the groom, the intended tone, the speaking time and anything that must not be mentioned. Tell it to use only your facts and mark missing details instead of inventing them.
- How long should a best man's speech be?
- Choose a speaking time that suits the wedding plans and put it in the prompt. The model can draft to that limit, but reading the speech aloud is the reliable way to find sections that need cutting.
- How do I make an AI-written best man's speech sound like me?
- Use stories and phrases you would actually say, then read the draft aloud and rewrite any polished or exaggerated wording. AI can arrange your material, but your own details, delivery and judgement provide the voice.
