Choose the kind of letter, add the facts, and get a prompt that has ChatGPT, Claude or Gemini write it with the right structure and tone.

This is an interactive tool. Use it at https://promptitin.com/free-tools/ai-letter-generator.

## How to use it

1. Tap the kind of letter you need.
2. Write the key details. The example in the box shows what helps.
3. Add who it's to and a tone if you like.
4. Tap Make my prompt, log in with one click, then run the prompt in your AI.

## 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.

## FAQ

### 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.

### Can I use it for formal or legal letters?

It's good for clear, formal writing. For anything with legal weight, like a contract dispute, have a professional check it.

### 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.
