Book a consultation →Who this is for
You don't need a compliance background to use Trestano. If any of these sound like your business, you're in the right place.
SMEs using AI tools
You already use ChatGPT, Copilot or industry-specific AI — but haven't formalised how it's governed or documented.
Teams adopting AI informally
Staff are signing up to AI tools without a central process, and you want visibility and control before it becomes a problem.
Businesses needing defensible documentation
You need an AI usage policy and risk assessments you can actually point to if a customer, regulator or insurer asks.
Organisations preparing for audits
A client due-diligence questionnaire, insurer review or procurement check is coming, and you want your AI governance ready first.
How it works
Three steps, no consultancy engagement, no jargon.
Register your AI tools
Answer plain-English questions about each tool your business uses — what it does and what data touches.
Get instant risk ratings
Every tool is classified as lower, medium or higher risk, with EU AI Act flags where they apply.
Download defensible documentation
Generate your AI usage policy and risk & impact assessments, ready to share with customers, insurers or regulators.
See where you stand in minutes
Free, no credit card. Register your tools and get an instant risk picture before you commit to anything.
Start free — check your AI compliance status →What makes Trestano different
Compliance tools are usually built for big enterprises with in-house legal teams. This isn't.
Built for UK regulations
Aligned with UK GDPR, ICO guidance and the EU AI Act where it applies to you — not a US template with the names changed.
Designed for non-technical teams
Plain-English questions and ready-made answers. No jargon, no developer required, no legal background needed.
No consultancy day rates
You get the structure and documents of a governance programme, without £1,500-a-day advisers on site.
Clear, predictable pricing
A free check, a one-off Starter payment or a simple monthly plan. You always know what you'll pay before you pay it.
Documentation you can hand over
Policies and assessments you can share with customers, insurers or a regulator — as a PDF, in your name.
Trusted foundations
Trestano is built on ISO 42001, ICO guidance, and industry-standard AI governance frameworks — so every document you produce stands up to scrutiny.
