EU AI Act · Article 50 · Applicable 2 Aug 2026

Price the fine, not the feature.

The Article 50 scanner is free — it's the way in. The Vault is the paid system of record: it registers each AI system, scans it continuously, holds the tamper-evident evidence, and exports an independently-verifiable dossier. You pay per AI system you put under proof, not per seat and not per gigabyte.

Currency

What's at stake vs. what it costs

Article 50 breaches are fined per the regulation — up to €15M or 3% of global turnover. Move the slider to your AI footprint.

The value metric

Per registered AI system

An AI system is the unit of regulatory scope — each carries its own Article 50 obligation set. You're billed on how many you put under proof, so price tracks risk, not headcount.

Seats

Free & unlimited in-tier

Invite your whole compliance, legal, and engineering org into the cockpit at no per-seat cost. We want everyone living in the evidence — that's the gravity that makes it the system of record.

Anchoring & storage

At cost, never the metric

The nightly Bitcoin batch costs the same whether it commits 10 receipts or 10 billion — one Merkle root, one transaction. Unlimited records ride the shared batch. The Vault holds 32-byte commitments, so storage is never billed. The only premium is on-demand sub-hour anchoring.

Straight answers

What exactly is "an AI system"?

It's the unit Article 50 regulates: a deployed model or model-backed feature that produces a regulated output — emotion recognition, biometric categorization, or synthetic/generative media — under one provider, for one purpose. Versions, retrains, and the seats around it don't add to the count; a genuinely separate system with its own purpose does. You register them, we meter them, and you can move the line by archiving ones you've retired.

What happens if I go over my tier's system count?

On Starter, you're never blocked. Your plan includes 3 AI systems, and each extra one is just +€100 a month (shown in your currency), prorated — and only while you keep it. Archive a system and the charge stops. We always show the cost and ask you to confirm first, so there's never a surprise. On Team and Business you simply upgrade in one click when you need more room. Need more than Business (60 systems)? Talk to us about Enterprise.

Are taxes and fees included?

Yes. The price you see is the price you pay — applicable country and regional taxes (VAT/GST) are included in the listed amount, no surprise line items at checkout. Bitcoin anchoring fees are passed through at cost and never marked up. Storage is never billed.

Monthly or annual — and can I switch?

Both. Monthly is month-to-month, cancel anytime. Annual is billed once and gives you up to 2 months free (the deepest saving is on Team). You can upgrade any time with prorated credit; downgrades take effect at the next renewal. Multi-year terms (deeper discount, rate locked) are available on Business and above — just ask.

What if it's not for us?

Every paid plan starts with a 14-day trial and is backed by a 30-day money-back guarantee. Lock the founding rate today and it stays at that price for the life of your subscription, even as list prices rise after launch.
