About AutoProof

AutoProof is a local-first Chrome extension that helps sellers, creators, and freelancers capture reliable snapshots of web pages for record-keeping and dispute resolution. With one click, AutoProof saves the current page as a web archive (MHTML), generates a cryptographic SHA-256 hash, and stores the file locally on your device. No accounts, no cloud storage, and no external servers are required. AutoProof is designed for situations where you need to document what a page looked like at a specific moment, such as product listings, receipts, policies, or published content. Key Features • One-click page capture as a web archive (MHTML) • Cryptographic SHA-256 hash for tamper detection • Files stored locally on your device • Export evidence files when needed • No tracking, no analytics, no data collection Who AutoProof Is For • Marketplace sellers • Online creators • Freelancers and contractors • Anyone who needs proof of what existed online Important Notes • MHTML files must be opened in Google Chrome for correct rendering • macOS Preview and Microsoft Word do not fully support MHTML files • AutoProof provides technical evidence files only and does not offer legal advice
