Human review logs, legal timestamps, PDF reports, FCA financial promotions, greenwashing checks, governance evidence and a cryptographically sealed audit trail you can verify on demand.
Don't take our word for it — verify a real audit record yourself →EU AI Act Article 50 enforcement begins 2 August 2026. AI generated marketing copy must be disclosed or documented. Agencies are in the frame.
What is already coming for your agency
Enforceable August 2026
If you use AI to write copy for clients, you must disclose it and prove it was reviewed before publication. The obligation sits with the creator, not just the brand.
Active now
Any copy touching investments, returns, crypto or financial products must be pre approved by an FCA authorised person. One unapproved ad triggers an investigation.
Enforcement ramping 2026
Sustainability claims like carbon neutral, eco friendly or net zero require substantiated evidence. Writing them without proof is now a regulatory offence across the EU.
Active now
UK advertising rules cover every ad your agency produces. Income claims, guarantees, testimonials and urgency tactics are all regulated. Agencies are routinely named in upheld complaints.
Updated 2023, active now
Influencer content, affiliate links and paid partnerships for US facing clients must all be clearly disclosed. Agencies managing these relationships carry liability if disclosure is missing.
Active now, UK
The CMA is actively pursuing greenwashing cases. Environmental claims must be accurate, clear and substantiated or your agency is exposed.
Sentinel checks copy against all of these, automatically, before it publishes.
Why Sentinel
Without a record, your agency has no defence. Sentinel logs every review with a timestamp, sealed into a cryptographic hash chain you can verify on demand, and generates a PDF report. When the regulator or client asks what you checked and when, the answer is instant, and provably untampered.
Professional indemnity insurers increasingly require documented compliance processes. A timestamped audit trail showing you reviewed copy before it published is exactly the kind of evidence they expect.
Your team ships fast. Compliance cannot be a bottleneck. Sentinel checks copy against FTC, GDPR, ASA, FCA and the EU AI Act in under 60 seconds. The compliance review happens before the brief leaves your desk.
Financial promotion rules are the highest stakes area of UK advertising law. One unapproved copy can trigger an FCA investigation for both you and your client. Sentinel checks financial copy at source, before it publishes.
The EU Green Claims Directive and CMA Green Claims Code are actively enforced. Agencies writing sustainability copy for clients are exposed if claims are unsubstantiated. Sentinel catches it before it becomes a headline.
Give Sentinel a URL and it fetches the live page, strips navigation and boilerplate, and runs a full compliance check against the actual published copy. If the page changes, run it again in seconds.
Paste the YouTube URL and Sentinel fetches the transcript automatically. Or drop in an audio file and Whisper transcribes it first. Every word goes through all 30 risk categories before a penny is spent on traffic.
Every check fires a webhook to any URL. Paste your Zapier hook into Settings and check results flow directly into Slack, your CRM or Google Sheets. The REST API lets you embed checking into your own systems.
The EU AI Act requires disclosure on AI assisted content from August 2026. If you use AI to write copy for clients, the obligation to disclose sits with you. Sentinel records what was checked, when, and by whom.
Every check can be rendered into a short video summary: the score, the flags, the risk breakdown, presented clearly. Send it to a client, drop it in a report, or use it to show a prospect exactly what you found on their site. No screenshots, no explaining a spreadsheet.
Who it's for
When a client campaign triggers an ASA or FCA complaint, the agency that wrote the copy is named too. Sentinel gives you a timestamped audit log sealed in a cryptographic hash chain, verifiable on demand, proving you reviewed it before it went out, plus white label reports, team seats, client workspaces and ongoing monitoring.
Sentinel replaces informal email review with a logged, timestamped audit trail. API access and webhooks let you integrate checking into your existing workflow. Every report is retrievable in seconds.
Sentinel checks copy against FCA financial promotion rules before publication and logs a timestamped audit record confirming it was checked.
GDPR, FTC, ASA, EU AI Act, ACCC and CASL checked simultaneously. Bulk check flags risk across every page in one run. Weekly monitoring flags changes before they become complaints.
