FAQ

Questions people ask before they write

Is this letter actually written by AI?

Yes. Each letter is generated by AI and tailored to the details you provide, so the draft reflects your specific complaint rather than a generic template.

Will this letter actually work?

A clear, professional complaint letter gives you a better chance of getting a response than a rushed email or phone call summary. It helps you present the facts and the outcome you want in a format companies take seriously.

Do I need to create an account?

No. You can generate a free preview and purchase your letter without creating an account first. After payment, we create an account automatically so you can access your unlocked letter again later.

What if I need a follow-up letter?

The 3-pack gives you three paid unlocks for $9.99. Credits are stored on your account and do not expire, so you can use the extras whenever you need them.

Is my payment secure?

Yes. Payments are handled by Stripe, and the app never stores your card details directly.
