Speech prompt

A copy-and-paste prompt for ChatGPT, Claude or Gemini that gets a professional speech on the first try, plus the cheapest model that does it well.

What most people type

best man speech for my brother's wedding, we fished together every summer growing up, keep it funny but heartfelt

It works, but the AI has to guess your brother's name, partner's name and fishing story, so the first answer usually needs another round. The version below asks for exactly what a professional would deliver.

The better prompt

Write a best man speech for my brother's wedding. Tone: funny but heartfelt.

Context: my brother and I fished together every summer growing up. Use that as the central thread of the speech.

Details to work in (use placeholders where I haven't filled them in):
- Brother's name: [brother's name]; partner's name: [partner's name]
- A specific fishing memory or funny story: [fishing story]
- What my brother is like as a person: [something specific about him]
- What I've noticed about him with his partner: [something specific about the couple]

Structure: a short opening that introduces me and my relationship to the groom, one or two funny stories, a turn to a sincere moment, and a toast to the couple. Keep the humor warm and never embarrassing or at the expense of the partner or guests.

Format: a speech I can read aloud in about [speech length, e.g. 3 minutes], written in plain spoken language, with the toast as the last line.

Replace the [brackets] with your details before you send it: brother's name, partner's name, fishing story, something specific about him, something specific about the couple, speech length, e.g. 3 minutes.

Why this version works

  • Made fishing the central thread. Anchors the speech in their real shared history.
  • Added placeholders for names and stories. Specific details make a speech land and avoid invention.
  • Added structure ending in a toast. Best man speeches follow a known arc.
  • Added speaking-length placeholder. Speeches are timed, so length matters.

  • Structure such as opener, stories, toast
