JAGRION · PLATFORM FOR DOCUMENTED CHANGE
Jagrion monitors selected public and authorised sources, stores every version and shows exactly what changed — with source, time and hash.
Both products share the same documentation engine. Choose the entry point that matches the source you need to follow.
PRODUCTS
Two entry points. The same documentation engine. Evidence Watch follows broad source types; PlanVagt follows official local-plan information for an address.
Monitor changes in regulation, supplier policies, official registers, APIs and critical web pages. Every preserved version includes a timestamp, hash and reviewable difference.
A traceable documentation layer for changes to GDPR Article 28 data processing agreements (DPAs), policies and public sources used in work involving DORA, EUDR, GPSR and Safety Gate.
Get notified when the official local-plan information for an address changes.
PlanVagt follows official planning information linked to a selected address and preserves its history for later review. The introductory pilot has limited access.
WHY NOW
Rules, supplier terms, plans and public registers are continuously corrected or replaced. A screenshot captures a moment; version history captures the sequence and makes the change verifiable.
SPECIALISED CAPABILITIES
These capabilities define the domain scope of an Evidence Watch pilot or a professional engagement.
Follow official environmental signals and external emergency sources. Jagrion combines alerts, maps and version history so each signal can be traced to its published source.
Preserve public trails across campaigns, domains, media, contracts and company registers. Analysis consistently separates documented facts, indications and hypotheses.
Every assessment is bound to its source and classified as a documented fact, an indication or a hypothesis for further research.
The source shows the fact directly.
Several public trails point the same way.
A question for further research.
HOW IT WORKS
Our complete engine is protected. Its verification logic is not: every conclusion must leave a trail that a third party can check.
Sources, versions, dates and hashes before interpretation.
The data route from its origin to the visible output.
Changes, branches, exceptions and absences under the same key.
The first verifiable divergence—or the exact evidence still missing.
DOCUMENTED EXAMPLES
REAL CASE · EUROPE · OFFICIAL SOURCE
REAL CAPTURE · HTTP 200Evidence Watch preserved the official Safety Gate homepage. The European Commission's 2025 report documents record volumes of alerts and actions.
An alert can be followed from product and risk to the countries and measures published by authorities.
Figures are from the official report published on 5 March 2026; the hash belongs to the Safety Gate source preserved by Jagrion.
REAL CASE · SOUTH AMERICA · OFFICIAL SOURCE
REAL CAPTURE · HTTP 200Evidence Watch preserved Cortolima's published satellite assessment with its original bytes, UTC time, hash and signed receipt.
Cortolima reported that the estimate was produced with satellite imagery and official cartography.
Observed fact: preserved official report. Affected area does not by itself establish the origin or motivation of the fires.
PROFESSIONAL SERVICES
Rapid audit of 3–10 files, versions or outputs. Deliverable: chronology, hashes, differences and next evidence objects.
Source → transformation → publication map, with controls, gaps and the first observable divergence.
A bounded comparison of two or more versions or periods. Deliverable: continuity map, adversarial checks, prioritized inspection points and an exact plan for the evidence still needed.
Practical training for legal, media, civil-society and data teams working with AI and evidence.
JAGRION RESEARCH
Research develops comparison methods, fail-closed prototypes and new ways to locate the first observable divergence. Documented use cases can form the basis of future products.
Current applied research covers democratic integrity, cybersecurity, transport, aviation and space.
No conclusion becomes stronger by hiding a contradiction.
If source, key or coverage is insufficient, the system blocks the claim.
AI extends the field of view; a person keeps final responsibility.
We protect the private method while making its outputs verifiable.
