Human content review and Article 50(4) compliance evidence for AI-generated text.
We do the actual review. We produce the documented evidence. You get an audit-ready compliance file you can hand to any regulator, enterprise customer, or auditor. Founded by a doctor, run by a network of credentialed reviewers.
Founding customer cohort opening Q2 2026. Procedure document and reviewer roster available on request. We are not a law firm.
The EU AI Act applies to your content. You probably do not have a compliance answer.
It applies even if you are not in Europe.
Article 50(4) attaches to AI-generated text published to inform the public on matters of public interest. If your content reaches EU users, you are in scope. There is no carve-out for non-EU publishers, and the regulation tracks the audience, not the office address.
The transparency obligation takes effect 2 August 2026.
From that date, AI-generated text in scope must either be labelled as artificially generated, or fall under the human review exemption. Article 99 penalties run up to EUR 15M or 3 percent of global annual turnover. Reputational exposure exceeds the fine.
System-level GRC vendors do not cover content.
Vanta and Drata cover SOC 2. Delve and Holistic AI cover the AI system. Nobody covers the article. There is no off-the-shelf product for "human reviewed this piece, here is the reviewer, here is the procedure, here is the evidence." That is the gap we close.
An audit-ready compliance file. Reviewed by named humans.
A continuing subscription that delivers the six documentation components an Article 50(4) human review claim is built on. Issued under your editorial designation, available on request to any regulator, customer, or auditor.
Editorial Review Procedure
A 12-section written procedure document, customized to your publishing workflow, versioned and dated. The artefact a regulator asks for first.
Named reviewer roster
The natural persons authorized to review your content, with credentials, languages, and signed reviewer agreements on file.
Editorial responsibility designation
A written designation of the editorially responsible person for content under this engagement. Three configurations available: customer-side, Sygil-side, or shared.
Per-article attestation log
One signed attestation entry per article, with reviewer, timestamp, methodology version, and a hash that lets a third party verify integrity.
Monthly evidence report
A bundled monthly report tying together the procedure version in force, the roster in force, and the attestation entries from that period.
Customer compliance vault
A secured store of every artefact above, queryable by article ID, exportable as a PDF package, retained for the regulatory limitation period.

Five steps from intake to attestation.
A continuing service, not a one-time audit. Every article in scope flows through the same five steps before it publishes.
Scoping call
A 15-minute conversation to confirm you are in scope, identify which content surfaces are covered, and pick the editorial responsibility configuration that fits your structure.
Procedure customization
We adapt the standard 12-section Editorial Review Procedure to your publishing workflow, sign-off chain, and tooling. You get a versioned PDF and a markdown source.
Article intake
You submit articles via the intake endpoint (web, email, or API) before publication. Each piece is logged with a unique ID, source, intended publication date, and audience.
Human review
A named reviewer from your assigned roster reads the article against the procedure, applies the agreed methodology, and records the review decision with their credentials on the entry.
Attestation and delivery
A signed attestation is generated, hashed, written to your compliance vault, and returned to you. The article is cleared to publish under the Article 50(4) human review exemption.
Why publishers choose Sygil.
Three things that no general compliance vendor, no AI detection tool, and no editorial agency can credibly offer in the same package.
Named, credentialed, on the record.
Every reviewer on your roster is a named natural person with verifiable credentials, a signed reviewer agreement, and a photo on the team page. Not a model. Not an offshore mystery box. Real names a regulator can phone.
We do Article 50(4). That is the entire product.
We do not sell general AI governance, model risk audits, or system-level posture management. One regulation, one obligation, one deliverable. The narrowness is the moat.
Editorial responsibility you can actually assign.
Editorial responsibility under the Code of Practice can sit with a credentialed individual. Our founder is an MD. The PhD network is real. Regulated verticals reward this in a way no SaaS competitor can copy.
Your enterprise customers are about to start asking.
EU enterprise procurement teams are already adding AI content questions to vendor questionnaires. Banks, pharma, media holding groups, and government tenders cite the AI Act in their 2026 vendor reviews. By Q3 2026 these questions are standard. A vendor who cannot answer them loses the deal, slows the renewal, and triggers a legal escalation every time. A vendor who can answer in one page closes faster. That one page is what we produce.
