LetterRuler is a free AI letter writer for the letters people find hardest to start: hardship letters, appeal letters and cover letters. You type the facts; it drafts a clear, polite letter that uses only those facts and marks anything missing with [brackets] for you to fill in.
How it works. Your text is sent to an AI model run by Cloudflare Workers AI, which returns a draft. We keep the free service sustainable with a daily limit.
What it will not do. It will not invent facts, promise outcomes, cite laws you did not mention, or write deceptive letters. It is not a lawyer, doctor or financial adviser.
Who is behind it. LetterRuler is published by Ecomparadise, LLC and edited by Alex. We build small, single-purpose tools, test them in real browsers, and explain plainly what they can and cannot do.
