How to write any letter in under three minutes using AI
Letter writing used to be one of those tasks that people would put off for days. The blank page, the finding of the right words, getting the tone just right. It used to take a while. AI has changed all of that completely.
Step one: describe the situation
Open your AI tool and describe what’s happened. Write it just as you’d explain it to a friend. For example: “I need to write a letter to my energy company. They’ve charged me incorrectly and I’ve been trying to get it sorted for two months with no response.”
Step two: tell it the tone you want
Add a sentence about how you want to come across. “I want to be firm and clear but polite. I don’t want to be aggressive.” This makes an enormous difference to the result.
Step three: read and adjust
AI will produce a draft in seconds. Read it through. If anything needs changing to sound more like you, just say so: “Can you make the opening a bit warmer?” or “Can you add a specific request for a response within 14 days?”
What kinds of letters work well?
- Complaint letters to companies or organisations
- Thank-you letters and cards
- Formal requests to councils or authorities
- Letters to doctors, hospitals or insurance companies
- Personal letters to friends or family when you want to get it just right
Not sure how to describe what you need? I made a free Build a Great AI Prompt tool that asks you a few simple questions and writes the request for you, ready to copy into ChatGPT, Claude, Gemini or Copilot.
A note on dates. Everything here was checked when it was written and I go back over my posts regularly to keep them up to date. Apps, prices and rules do change, so for anything important a quick look at the official source is worth it.
Want to try this yourself?
Letter writing with AI is something Kevin can take you through properly at one of his workshops or in a follow-up session after a free library talk. You’ll leave having done it yourself and knowing you can do it again at home. Just ask Kevin to show you.
