Why this exists

An official letter in a language you half-read is a special kind of fear. It sits on the table all evening. You photograph it for a friend who "knows German". You paste it into a translator and get words without meaning: what is a Vollstreckungsankündigung, and is fourteen days a lot?

The people who know — translators, tax advisers, lawyers — charge €50–150 to tell you what the letter is. Not to solve it: just to name it and point at the date. That price exists because the knowledge is scattered across official portals in officialese.

What's This Letter does the naming and the pointing. It reads your letter twice — once to extract what it says, once to verify every claim against the document — and answers three questions: what is this, who sent it, by when must I act. Key passages are quoted word-for-word and translated. Facts about the notice type come from the authority's own pages, checked and dated.

It stops exactly where advice begins. It will not tell you whether the claim is right, what you owe, or what to argue — that is work for a licensed professional in your country, and pretending otherwise would make a $5 tool dangerous. What it does instead is turn a frightening envelope into a plain sentence and a date, in your language, in a minute.
