What PaperLens actually finds
Concrete things, not generic promises. Every analysis returns these by default.
Auto-renewals you'd miss
Lease and subscription clauses that quietly extend you for another month or year. PaperLens flags every one with the deadline you need to remember.
Fees that aren't in the headline
Pet fees, late fees, 'amenity' fees, resident benefit packages, processing fees. Itemized in your output so you know the real monthly cost before you sign.
Clauses that may be unenforceable
Non-competes in California. Non-refundable deposits in some states. Penalty clauses that exceed legal caps. PaperLens cites the relevant rule when it applies in your locale.
Billing errors and duplicate charges
Industry studies put medical billing error rates around 1 in 10. PaperLens cross-checks procedure codes, dates, and your EOB against the invoice.
The questions you should ask
Every analysis ends with 3-5 specific things to clarify with the landlord, employer, insurer, or doctor. Not generic — pulled from your specific document.
Plain-language definitions
Every piece of jargon in your document defined inline. 'Indemnify', 'subrogation', 'co-insurance', 'deductible' — explained as if you've never seen them before.

Resumen
Contrato de arrendamiento de 12 meses desde el 1 de marzo. Renta mensual $2,150 con depósito de $4,300. Se renueva automáticamente mes a mes salvo aviso escrito con 60 días. El inquilino paga servicios; el propietario paga la HOA. Mascotas permitidas con tarifa no reembolsable de $400.
Riesgos destacados
- MediumAuto-renewal at month-to-month
Lease auto-renews unless 60 days notice given. Easy to forget; sets up an involuntary stay-on past the year.
- HighNon-refundable pet fee
$400 fee not held in escrow and not returned even if the unit is left undamaged. Restricted in California, Oregon, and others.
Why Pro pays you back
$6.99/month is roughly the cost of one missed clause. Here's what Pro users typically use it for in a single month.
PaperLens finds:
Duplicate charges, miscoded procedures, services your insurance covers but the provider didn't file
↳ Industry studies estimate 80% of medical bills contain at least one error
PaperLens finds:
Auto-renewal deadlines, hidden rent escalators, fees disguised as 'resident packages'
↳ Catching a single month of unwanted auto-renewal pays for 2 years of Pro
PaperLens finds:
Equity vesting cliffs, non-compete scope, on-call expectations buried in 'duties'
↳ One round of negotiation usually beats your annual subscription cost many times over
PaperLens finds:
Out-of-network surprises, claim filing windows, exclusions for things you actually need
↳ Switching plans to fill a coverage gap can save thousands per year
PaperLens explains documents — it doesn't guarantee savings. Specific outcomes depend on your situation. We don't store your documents past the retention window and we don't sell anything to insurers, landlords, or employers.

Preguntas frecuentes
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.
