By investigators, for newsrooms.
Online sources disappear. Your evidence shouldn’t.
Capture, preserve, and re-use web content — creating tamper-evident capsules that hold up under scrutiny. On your infrastructure, under your control.
In pilot with European investigative newsrooms.

How it works
From capture to published evidence
One workflow — from the moment you capture a page to a verifiable source in your published story.
Capture
One click turns any page — social media and logged-in content included — into a faithful, interactive capsule, made right on your machine.
Organise & collaborate
Build a shared source desk: organise captures, deep-link to the exact highlight, and collaborate with your team.
Publish & embed
Keep a capsule private, share it with your team, or publish and embed it on your own site. Private by default — nothing leaves your machine unless you choose.

A byline for the evidence
Journalism has always run on attribution — who saw it, who stands behind it. Chain of custody is the byline extended to your sources. And it forces an honest reckoning with what a faithful record actually contains.
Every investigation should start with an empty browser
A small ritual borrowed from the Berkeley Protocol — and what it really protects. A note on hygiene before evidence.
Your screenshot won't survive a legal challenge. Here's what will
Chain of custody isn't just for courts. When a reader asks "how do I know you saw this?" — here's what journalists and newsrooms need to know about web archiving and chain of custody.
An archive that rewrites history: what the Archive.today ban means for your sources
Nearly 700,000 citations removed after an archiving service was caught tampering with its own captures. Here's what it means for reporters who rely on third-party archives as evidence.
