ProofSnap

ProofSnap provides digital evidence capture and certification tools for individuals and professionals who need to preserve online material. Its Chrome and Edge extension captures web pages in one click, creating evidence packages with SHA-256 hashes and an RSA-4096 digital signature. Professional plans add a blockchain timestamp, while capture options include single pages, multi-tab sessions and signed video proof. A Trust Verifier lets users check package hashes, signatures and timestamps, and sample packages and guides are available for review.

For customers who prefer assistance, ProofSnap offers done-for-you services for web pages, email threads, chat exports, social media posts, YouTube videos and documents, photos, audio and other files. These services return signed, timestamped packages or readable, line-numbered transcripts, with several options offered within 48 hours. The company also provides evidence services for insurance investigations and resources for law firms, investigators, journalists and people handling disputes. Its guides cover topics such as screenshot authentication, messaging records and court evidence.
