The AI-powered evidence platform for IP litigation teams. Capture, timestamp, and preserve digital evidence with court-ready chain of custody — in seconds, not hours.
The problem
Today, boutique IP firms lose billable hours — and sometimes cases — to the laborious, error-prone process of manually capturing and archiving digital evidence. Screenshots lack legal weight. Web content disappears overnight. Courts increasingly scrutinise chain of custody.
Counterfeit listings, infringing posts, and domain content disappear within hours of detection — often before you can capture it.
Courts and opposing counsel increasingly challenge unverified screenshots. You need timestamped, cryptographically sealed capture.
Paralegals spend 3–5 hours per case manually documenting, formatting, and organising evidence packages. Perdura does it in minutes.
Built specifically for IP attorneys and their paralegals — not generic web archiving.
Describe a task in plain English. Our AI agent autonomously navigates the web — across multiple pages, dynamic content, and complex UI interactions — to capture exactly what you need.
Every capture is cryptographically sealed with a trusted RFC 3161 timestamp the moment it's taken. Tamper-evident, verifiable, and accepted in courts worldwide.
Generate formatted PDF bundles with embedded metadata, hash verification, and chain-of-custody documentation — ready to file or send to opposing counsel in one click.
Set recurring capture schedules on infringing URLs, marketplaces, or social accounts. Perdura monitors continuously and alerts you the moment new evidence appears.
Organise all evidence by matter. Search, tag, and export across multiple cases. Purpose-built for litigation boutiques managing 10–50 active matters at once.
Every action — capture, export, access — is logged in a tamper-proof audit record. Full traceability from collection through to courtroom, with no gaps in the chain.
Type a plain-English instruction — "Capture all listings for 'Rolex Submariner' on this counterfeit marketplace, including seller pages and checkout flow" — or paste a list of URLs into the structured capture mode. No technical knowledge required.
AI Agent ModeOur Browser Use AI agent autonomously browses, clicks, scrolls, and extracts — across as many pages and interaction steps as needed. A real-time task log lets you follow along or run other work while it captures. Full-page screenshots, HTML source, and video are preserved.
Autonomous CaptureThe instant each page is captured, Perdura computes a SHA-256 hash and applies a trusted RFC 3161 timestamp from a certified authority. The seal is embedded in the evidence record and cannot be altered retroactively.

Perdura was designed from the ground up to meet the evidentiary standards of IP litigation — not retrofitted from a generic archiving tool.
"Courts are increasingly scrutinising digital evidence. A screenshot without provenance is a liability, not an asset. The chain of custody begins the moment you capture — not the moment you file."
