AI Sigil is compliance software for companies that ship or use AI. You register each AI system you run — what model, what data, what it decides — and the platform maps it against a maintained library of 28 regulatory frameworks: the EU AI Act plus 27 national and state AI laws, with the obligations, deadlines and documentation each one demands.
This is a different animal from everything else in this directory. Nobody buys compliance software because they want to; they buy it because the EU AI Act’s obligations started landing in 2025 and the paperwork alternative is a spreadsheet someone forgets to update.
What it costs
Tiered subscriptions: a Self-Service plan and a Dedicated plan that adds an implementation lead, SSO/SAML and procurement paperwork (DPA, MSA, SOC reports). There is a 14-day free trial of the full platform with no card. Their pricing page renders exact figures in-app rather than in plain text, so we won’t quote numbers here — check their pricing page directly.
What we can’t tell you
We run AI systems, not an AI compliance programme, so we have not stress-tested the framework library against real legal advice — and you should not treat any tool in this category as a substitute for it. What a register like this genuinely does is make the lawyer conversation cheaper: you arrive with an inventory instead of paying counsel to build one.
