Frequently Asked Questions

Upload any contract, invoice, estimate, or financial document (PDF, DOCX, TXT, JPG, PNG, HEIC — up to 50 MB). Our AI forensic engine scans the document for hidden surcharges, duplicate billing, inflated pricing, deceptive financing terms, and suspicious language. The analysis generates an evidence-based report with exact page-level citations, quoted evidence from your document, and actionable negotiation recommendations.

HiddenFeeAI detects 10+ categories of financial risk: hidden surcharges (undisclosed fees added to invoices), duplicate billing (charges billed multiple times), inflated pricing (marked-up rates beyond market value), deceptive financing (misleading loan or payment terms), contractor markups (inflated labor and material costs), warranty gaps (missing or limited coverage terms), telecom junk fees (hidden carrier and service charges), banking penalties (unexplained account and overdraft fees), insurance manipulation (claim adjustments and overbilling), and dealership financing (marked-up interest and add-ons).

A single document analysis costs $29.99 USD — a one-time payment with no subscriptions, no recurring fees, and no hidden charges. One detected hidden surcharge can potentially save you hundreds or thousands of dollars.

We support PDF, DOCX, TXT, JPG, PNG, and HEIC files up to 50 MB. Scanned documents and photographs are processed using OCR extraction.

You can drag and drop your file onto the upload area on our homepage, or click to browse and select a file from your computer. The upload is encrypted in transit using TLS 1.3.

HiddenFeeAI extracts the actual pricing language, fee structures, and contractual terms from your uploaded document. The AI then analyzes this text against our forensic detection models to identify hidden surcharges, inflated pricing, duplicate billing, deceptive financing, and suspicious legal language. Unlike generic AI tools, every finding includes exact page references and quoted evidence from your specific document — we never hallucinate or invent findings.

Not necessarily. If your document is straightforward and contains no hidden fees, deceptive language, or unusual pricing structures, the AI may return minimal or no findings. We do not guarantee that every document contains detectable issues. This is clearly stated as a non-refundable situation in our refund policy.

Unlike generic AI chat tools that may fabricate responses, HiddenFeeAI only reports findings that are directly supported by text extracted from your uploaded document. Every finding includes exact page-level citations with quoted evidence, so you can verify each claim against the original source.

Absolutely. All uploads are encrypted in transit using TLS 1.3 and stored encrypted at rest using AES-256. Documents and extracted text are automatically deleted from our servers after the analysis is complete. We do not sell, share, or use your documents for AI training purposes.

No. HiddenFeeAI provides AI-generated analysis and findings for informational purposes only. The output does not constitute legal or financial advice. You should consult with a qualified attorney or financial advisor before making decisions based on our analysis.
