Free AI letter writer

By Alex, editor · Updated October 25, 2026 · Published by Ecomparadise, LLC

Hardship letters, appeal letters, cover letters and more. Type your facts, get a clear, honest draft in seconds. No sign-up.

Write plain facts: what happened, dates, amounts, and what you want. Use the example to see how it works. Use last 4 digits only for account numbers.

Free, no sign-up. Uses only the facts you type and marks missing details in [brackets]. Daily limit applies.

Not legal, medical or financial advice. LetterRuler drafts wording from the facts you type. It does not know the rules that apply to your situation and cannot promise any outcome. For eviction, immigration, employment, insurance, tax or court matters, have the draft reviewed by a qualified professional or a free legal aid service before you send it.
