The idea
Everyone has a parking ticket they think is unfair, or a refund a company keeps dodging. Most people never write the letter, because it's annoying and they don't know what to say.
An AI chatbot can write a letter, so why would anyone pay? The bet: people pay to skip the work. The tool asks the right questions, writes a finished letter in the right format, and hands it over as a PDF ready to send.
How it works
- You pick the kind of letter and answer a few questions in plain words.
- The AI writes the letter. You see the first part free.
- If you like it, you pay, and the full letter unlocks as a PDF you can download, share or print.
The AI only uses what you tell it. It doesn't invent laws, facts or deadlines, and it refuses to write threatening or fake letters.
The tools behind it
- Claude (an AI by Anthropic) writes each letter. It's paid per letter, about a cent or two each (an estimate).
- Cloudflare hosts the website, on its free plan.
- Stripe handles payments, so the card details never touch the site.
- The buyer's own browser turns the letter into a PDF, so no extra service is needed.
No office, no developer, no monthly software bills. The code was written with AI too.
