Tips

  • Dates, order numbers and names make a complaint letter work. Put them all in.
  • For a cover letter, paste two or three lines from the job ad into the details.
  • Resignation letters should be short and kind. Save the reasons for a conversation.
  • Ask the AI for a shorter version if the first draft runs past one page.

Frequently asked questions

Is this letter generator free?

Yes. A free PromptItIn account writes the prompt, no card needed.

What kinds of letters can it write?

Cover letters, complaints, resignations, requests, recommendations, apologies and thank-you letters. For anything else, pick the closest kind and describe it in the details.

Why do I get a prompt instead of the letter?

You run the prompt in your own AI, then ask it for changes until the letter is right. The prompt keeps all your facts so nothing gets lost.
