Find clauses that have been added, modified, or deleted in a contract.
When you receive the V2 of a 30-page contract, it is impossible to verify changes like a sneaky comma or an altered clause with the naked eye. Our comparator extracts the raw text from your two PDF files, then highlights additions in green and deletions in red.
The entire text scan and delta processing happen via your own web browser's JavaScript engine. None of your sensitive legal documents ever leave your computer.
Select the original version (A) of your document and the revised version (B) to audit respectively.
The local engine synchronously extracts the raw text from each document and runs a word-by-word comparison.
Instantly inspect the analyzed lines of text neatly highlighting every single addition and deletion.
During the renegotiation of commercial contracts, corporate bylaws, vendor quotes, or terms of service, proofreading a multi-page document by eye is tedious, exhausting, and highly risky. A single clause altered, added, or quietly omitted can carry heavy legal or financial ramifications. Our semantic comparator provides an impartial, objective, and instant audit of structural modifications.
Technically, this application orchestrates the pdfjsLib engine to asynchronously scrape textual tokens from your files via the `getTextContent()` method. These sanitized string payloads are then submitted to the jsdiff engine through the efficient `Diff.diffWords` API. The algorithm computes the variance tree and applies surgical Tailwind CSS classes: text highlighted in green represents additions, while text struck through in red indicates deletions. Since the analysis runs entirely offline, your business trade secrets remain safe.
The comparison script analyzes digitally encoded characters natively embedded within the PDF architecture. If your files originate from a photocopy or an un-OCRed image-only scanner, no text layer can be extracted or compared.
Yes. That is the exact purpose of a decentralized serverless utility. The text comparison occurs locally inside your web browser's JavaScript memory heap. Your legal agreements remain 100% private and secure.
