The online letter generator writes 12 letter types: cover, business, formal, recommendation, resignation, complaint, thank-you, apology, invitation, leave application, inquiry, and personal letters. Pick a type, set one of 9 tones, and describe your topic, and the generator builds the right structure for it.

How do I write a letter with this AI letter-writing tool?

Enter the topic or purpose of your letter, then add who will receive it. Choose a letter type and tone, set a length, and add any extra details you want included. Click Generate Letter, and you get a complete draft in seconds, with a date line, salutation, body paragraphs, and a signature, ready to edit before you copy or download it.

What does the AI Suggest button do?

The AI Suggest button fills in the Topic or Target Audience field for you instantly if finding the right words is hard for you. Tap it next to either field when you are not sure what to type, then accept the suggestion as it is or edit it before you generate the full letter. It is a fast way to get started without a blank field.

Can I edit the letter after it is generated?

Yes, the generated letter is fully editable right in the output panel. Click into the text to change any wording, swap in real names and dates for the placeholders, or adjust a paragraph until it sounds like you. Your edits are kept when you copy or download the letter, so the final version is exactly what you send.

Can I download the letter as a Word or PDF file?

Copying your letter is free for everyone, with no limit on how many times you copy it. Downloading it as a formatted Word or PDF file is available on paid plans, which is useful when you want a ready-to-print document. You can always copy the text and paste it into your own document to save time and effort.

Is the AI letter generator free to use?

Can I use ChatGPT instead to write a letter?

Does this free letter maker store or share the details I enter?

No, the tool does not store or share the details you enter. Your topic, audience, and any additional details are used only to generate your letter in that session, so you can write freely without worrying about your information being kept or passed to a third party.
