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.

1

Register your AI tools

Answer plain-English questions about each tool your business uses — what it does and what data touches.

2

Get instant risk ratings

Every tool is classified as lower, medium or higher risk, with EU AI Act flags where they apply.

3

Download defensible documentation

Generate your AI usage policy and risk & impact assessments, ready to share with customers, insurers or regulators.

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.
