Just pick the type, set a tone, and describe your topic - the generator structures the whole letter for you.

How do I write a letter with this tool?

Enter the topic or purpose of your letter, tell us who will receive it, choose a letter type and tone, and add any extra details you want included. Click Generate and you get a complete letter in seconds - with a date line, salutation, well-organized body paragraphs, a courteous closing, and a signature line. You can then edit it directly in the output before copying or downloading.

What does the AI Suggest button do?

If you are not sure what to type, the AI Suggest button next to the Topic and Target Audience fields instantly fills in a relevant suggestion for you. It is a quick way to get unstuck - accept the suggestion as-is or tweak it to fit your situation before generating the full letter.

Can I edit the letter after it is generated?

Yes. The generated letter is fully editable right in the output panel - click into it and change any wording, swap in real names and dates for the placeholders, or adjust a paragraph. Your edits are kept when you copy the letter or download it, 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. Downloading it as a formatted Word (.docx) or PDF file is available on paid plans - useful when you want a ready-to-print, professional document. You can always copy the text and paste it into your own document at no cost.

How do I write a formal letter?

A formal letter follows a clear structure: your address and the date at the top, the recipient's details, a formal salutation such as "Dear Mr. Smith", body paragraphs that state your purpose clearly and politely, a formal closing like "Yours sincerely", and your name and signature. Select "Formal Letter" as the type, set a professional or formal tone, and the generator builds every one of these parts for you - so you get a correctly formatted formal letter without memorizing the rules.

Can I use it to write a cover letter for a job?

Yes - cover letters are one of the most popular uses. Choose "Cover Letter" as the type, enter the role or company as your topic, and add key details like your experience or the job title. The AI writes a tailored, professional cover letter you can edit and send. Pair it with the Grammar Checker to proofread before you apply.

Is the AI letter generator free to use?

Yes - you get 3 free letter generations right away with no sign-up required. Create a free account for more generations across all 30+ writing tools, and paid plans add unlimited letters plus Word and PDF downloads.
