How do I write a resignation letter with AI?

Give ChatGPT or Claude your job title, notice period, last working day and preferred tone, and ask for a short professional letter under 150 words that thanks your employer and offers help with the handover. Check your contract for your notice period, and add names and dates yourself before sending.

Copy-and-paste prompt

Swap the bits in [square brackets] for your own details.

Write a short, professional resignation letter. I'm leaving my role as [job title] at [company placeholder]. My notice period is [length], so my last day will be [date]. Tone: [warm/neutral]. I'd like to [thank my manager for X / offer to help with handover]. Keep it under 150 words and don't mention [anything to avoid].

How to do it

  1. Open ChatGPT or Claude and start a new chat.
  2. Copy the prompt below and replace everything in [square brackets] with your details.
  3. Check your contract for your notice period before you send it.
  4. Add your real names and dates yourself.
