About this tool

Official letters to offices, banks and institutions — correct layout, one clear request, one page.

Letters to institutions follow conventions that are never written down anywhere but are immediately obvious when missed. Block layout, a subject line, one request per letter, and a reference number if you have one.

Describe what you need and who it is going to. The letter comes back in conventional layout with placeholders for the addresses and date, a subject line that tells a clerk where to route it, and a single clear request — because a letter asking for three things typically gets one of them answered. Anything you did not supply comes back as a bracket. It stays to a page, which is the length that gets read by someone working through a stack of them.

How to use

  1. Say who the letter is going to, describe exactly what you are asking for with any reference numbers, and choose a tone
  2. Press Generate and give it a few seconds.
  3. Copy what you need, or generate again for a different take — every run is fresh.

Frequently asked questions

Because institutions route letters by subject. A letter asking three unrelated things typically gets forwarded once and partially answered. Separate letters get separate answers.

It comes back as a placeholder for you to fill in. Getting the exact office or department right matters more than the wording for whether the letter reaches someone who can act.

Whatever the institution specifies. Where something may need proving later, posted mail with proof of delivery is still the safer record — keep a copy either way.

No. Your input is sent to the AI provider this site is configured to use purely to generate your result, and is not stored here afterwards. There is no account for it to be attached to. Even so, keep passwords, financial details and other people's private information out of it.

The site owner selects one model that powers every tool here, so there is nothing for you to configure. Describe what you need, press Generate, and read the result before you use it.
