Use Cases

From bloggers preserving their sources to lawyers building court-ready evidence — Cataproof adapts to your needs.

Content Creator & Blogger
Prove your sources, archive references, protect against link rot
The Problem

Online content changes or disappears without warning. Screenshots can be faked. Bloggers and journalists have no easy way to prove their sources were real at the time of writing.

The Solution

Capture any web page with Cataproof and receive a cryptographically signed evidence package. Download it, share a verification link, or embed the interactive <cataproof-viewer> directly on your website so readers can verify your sources themselves.

How it works
Enter a URL
Paste the page you want to preserve as evidence.
Capture
Cataproof visits the page in a secure, isolated browser and captures everything.
Download or embed
Get a signed ZIP package, share a verification link, or embed the viewer on your site.
Readers verify
Anyone can independently confirm the evidence is authentic and unmodified.

Lawyer & Notary
Court-admissible digital evidence with full chain of custody
The Problem

Legal professionals need web evidence that courts accept. Simple screenshots lack provenance, timestamps are easily disputed, and manual notarisation of web content is slow and expensive.

The Solution

With Cataproof, you can add qualified RFC 3161 timestamps, session video recordings, full network traffic logs, and chain of custody documentation to any capture — everything needed for court proceedings, all in one tamper-proof archive.

How it works
Start an interactive session
Navigate to the target content, including pages behind logins.
Record everything
Video, screenshots, HTML, and full network traffic are captured automatically.
Qualified timestamp
An independent RFC 3161 authority certifies exactly when the evidence was captured.
Receive your evidence package
Download a tamper-proof archive with chain of custody documentation included.
