Your PESEL stays in Europe.
We built ExplainMyLetter for sensitive documents. So we don't treat your data like the average AI tool does.
EU-hosted AI
We use Mistral, a French AI company. Your letter is processed in EU data centers. Not the US. Not China. Not 'the cloud.'
PII redacted before the AI sees it
PESEL, NIP, IBAN, Steuer-ID, email, phone — all stripped to placeholders before your letter leaves our server. The AI literally can't see them.
Never stored, never trained on
Your file is processed in memory and discarded. We pay Mistral the contract tier that prohibits training on customer data.
GDPR-native
Built in the EU, for EU residents. Data Processing Agreement available on request.
Three steps. Thirty seconds.
Built for the dread of opening official mail in a language you don't speak — not for enterprise document workflows.
Snap, paste, or upload
A photo of the envelope, a pasted email, or a PDF — we read PDFs, JPG/PNG, and text. Multi-page letters too.
Translate + explain in context
Polish, German, Spanish, French, Italian, Ukrainian, Czech in. English, German, Spanish, Polish, or Ukrainian out. With local context — not just word-for-word translation.
Deadlines extracted automatically
Every date with a deadline shows up as an action item. Visual countdown for the urgent ones so you don't miss the 14-day appeal window.
Just the actions you need to take
We only list what the letter actually requires. No 'consider doing X.' No padding. If there's nothing to do, we say so.
Why not just paste it into ChatGPT?
Because ChatGPT is general. It can translate decyzja o ustaleniu podatkubut it doesn't know that the appeal window starts on delivery, not signature date. It doesn't know that this Wrocław property tax letter has four quarterly payments. And you really shouldn't be pasting your PESEL into a public chatbot.
ExplainMyLetter is built for one job and does it without sending your PESEL to a US server.
