Evidrop is secure evidence sharing software built for attorneys, law firms, and legal professionals who need to share sensitive media files — video, audio, and images — with proof of integrity and viewer accountability. When you share evidence through Evidrop, every video frame is watermarked with the viewer's email address. If shared evidence is leaked or screen captured, the viewer's identity is embedded in the content. SHA-256 cryptographic hashing at the point of upload creates a tamper-evident record that proves files have not been modified. The platform automatically generates FRE 902(13) self-authenticating evidence certificates formatted under 28 U.S.C. § 1746, documenting the hash verification, chain of custody, and access history in a single court-ready document. Every access is logged with the viewer's IP address, timestamp, and browser information. Evidrop offers two storage modes: auto-expiring delivery for time-sensitive sharing, and permanent vault storage with FRCP 37(e) litigation hold capability for active cases. Access notification emails alert you when someone views your evidence. Free tier available with 200MB storage. Professional plan at $149/month includes 50GB storage and vault mode. Enterprise plan at $499/month includes 500GB storage and all features.
