Paste text, upload a file (PDF, DOCX, TXT, or an image), or snap a photo. Hidden Catch reads the document with AI and returns a plain-English, severity-ranked risk report that quotes the clauses it flags as risky, explains them, and suggests what to do about them.

Not by us. Documents are processed ephemerally to generate your report and are never stored on our servers. The text is analyzed by Anthropic under API terms that do not use it to train models. Anthropic automatically deletes API inputs and outputs within 30 days, and keeps them longer only if its automated safety systems flag a request (up to 2 years) or where the law requires. See our Privacy Policy for the full picture.

Hidden Catch reviews documents and returns reports in over 10 languages, including English, Spanish, Portuguese, and French. You can also receive the report in a language different from the source document.

Everything runs on credits. A typical text scan costs 1 credit; larger documents and scanned-image pages add work, so OCR and analysis are quoted additively. The optional follow-up tools each cost 1 credit: asking up to 10 questions about a report, comparing a re-scan against a previous report, or drafting a reply. The official source check costs 1 credit for a normal document. The complete quote is shown before any paid OCR or AI analysis starts. Credits come in one-time bundles, starting at $9 for 5 credits, and purchased credits never expire.

You can, but you get a different tool. A general chatbot gives you a one-off answer that depends on how well you prompt it, and temporary chats may still be retained for safety review. Hidden Catch is purpose-built for document risk review: the accepted document is reviewed against a consistent risk checklist, flagged clauses are quoted verbatim, and severity is kept separate from the plain-language explanation. Your document is never stored on our servers, and the only copy that exists anywhere is a temporary one our AI provider, Anthropic, keeps under its API retention policy, deleted within 30 days unless a request is flagged for safety review. Reports stay only in the current tab unless you download the PDF yourself.

No. Hidden Catch is an informational tool that helps you understand a document. It is not a law firm and does not provide legal advice. For decisions with significant consequences, consult a qualified attorney.
