GetProofAnchor is a web evidence platform that helps individuals, companies, legal teams, auditors, journalists, and investigators capture and preserve online content as verifiable digital proof.
Instead of relying on ordinary screenshots, GetProofAnchor creates a tamper-evident evidence bundle that can include a screenshot, video, captured HTML, extracted text, metadata, cryptographic hashes, a verification report, DNS, TLS and timestamping records. The goal is to make it easier to prove what existed online at a specific moment in time — even if the page is later changed, deleted, edited, or disputed.
GetProofAnchor is designed for situations where online content matters: website changes, social media posts, public claims, misleading information, policy pages, competitor content, compliance records, online harassment, defamation, disputes, investigations, and regulatory documentation.
Each capture is built with integrity in mind. The evidence package can be independently reviewed, verified, and archived, helping users maintain a stronger chain of custody than a normal screenshot or browser printout. GetProofAnchor supports public web captures and is built with forensic-style documentation, auditability, and long-term verification in mind.
The platform is especially useful for lawyers, compliance teams, journalists, OSINT researchers, businesses, and anyone who needs reliable proof of online content before it disappears.

KDE's okular might be a good choice. I haven't personally used it for epub but I know it supports it. https://okular.kde.org/. - Source: Hacker News / over 3 years ago
