How to read a Mietvertrag
Mietvertrag documents are full of language designed by lawyers for lawyers. PaperLens reads yours in seconds and explains every clause in plain language. Below is a guide to what to look for, in your language.
Häufige Fragen
Is this legal advice?+
No. PaperLens explains what your document says in plain language. For decisions that matter, talk to a qualified professional. We're a reading aid, not a lawyer.
How accurate is the AI?+
PaperLens uses Google Gemini 2.5 Flash with structured output and per-document-type prompts. We benchmark against a curated test set of 200+ real documents and flag low-confidence results. The AI is good — it's not perfect. Always treat the output as a starting point, not the last word.
What documents work?+
Leases, employment contracts, NDAs, insurance policies, medical bills, EOBs, tax letters, mortgages, terms of service, privacy policies. PDFs and photos up to 20 MB.
How is my data handled?+
Uploads are stored privately in your account folder, scanned by a single AI model, then auto-deleted. Free: 1 day after analysis. Paid: 30 days. We don't sell, share, or train on your documents. The repo is open source — verify it yourself.
What languages?+
Output in 5 today (English, Spanish, Portuguese, German, French) with 15+ more rolling out. The analysis itself works on any language the document is written in — we read your German lease and explain it in Spanish if that's your locale.
What if I cancel?+
You keep access through the end of the period you paid for. Your analysis history stays in your account. Cancel from /dashboard → Manage subscription, no email required.
