• WHAT KLAUS DOES

Six building blocks that make you AI Act ready.

Klaus covers the four areas of obligation under the AI Act: risk management, documentation, human oversight and training. Step by step, in plain language, without a law firm.

Risk classification

Klaus reviews your AI applications and assigns them to the four EU risk categories, from minimal to prohibited.

Mandatory documents, automatically

Declaration of conformity, risk management, logging concept. Klaus generates everything at the click of a button.

Obligations checklist

A concrete to-do list for every AI system. What do you need to do, by when, and how do you prove it?

AI training for your team

Article 4 requires AI literacy in your organisation. Ready-made learning units, done in 20 minutes.

Incident reporting

High-risk AI must report serious incidents: to the right authority, within the right deadline. Klaus prepares the report and guides you through the process step by step.

Always up to date

The EU AI Act is being supplemented by implementing acts. Klaus keeps track and tells you what changes.

• THE 4 RISK CATEGORIES

Not all AI is the same.
Klaus knows the difference.

The EU AI Act sorts AI systems into four risk categories. What you need to do to comply with the AI Act depends on which AI systems you use.

Classify your AI
LEVEL 01OK
Minimal

Spam filters, recommendations, AI in toys

Practically no obligations. Klaus documents it anyway, so you have the answers ready in an audit.

LEVEL 02Transparency
Limited

Chatbots, deepfakes, generated text

You have to tell users: "You are talking to an AI." Klaus provides the ready-made disclosure texts.

LEVEL 03Strictly regulated
High

Applicant scoring, credit checks, education, medicine

Risk management, logging, human oversight, conformity assessment. Klaus guides you through all of it.

LEVEL 04Off limits
Prohibited

Social scoring, manipulative targeting, emotion recognition in the workplace

Stop immediately. Klaus spots it early and suggests legally sound alternatives.

• HOW IT WORKS

Three steps to being AI Act ready.

No meetings with lawyers. No bloated spreadsheets. Klaus asks questions, you click answers.

1Step 1

Build your AI inventory

You tell Klaus which AI tools your team uses and which ones you develop yourselves: purchased solutions like ChatGPT, plugins or your own AI systems. Klaus gathers this in 5 minutes.

2Step 2

Classify the risk

Klaus assigns every application to the right risk category. For high-risk systems, the applicable obligations are named directly, turned into concrete tasks and completed automatically wherever possible.

3Step 3

Roll out documents

Klaus generates conformity documents, disclosure texts and logging templates. The result is a complete compliance package, ready for audits and requests from authorities.

Three areas of law, one guided process

Using AI in a legally sound way is not a single discipline: the EU AI Act, data protection and professional law all interlock. Klaus covers all three in one guided process. You answer questions instead of reading legal provisions.

• ABOUT US

We are simply Legal.
From Würzburg, for all of Europe.

We started in 2019 with a simple question: Why is data protection so complicated for small teams? The answer became Dieter Datenschutz: software that turns the GDPR into a to-do list.

When the EU AI Act arrived in 2024, we knew what to do: Klaus, Dieter's younger brother, now translates AI compliance into the same plain language. Both are built by the same team of lawyers, developers and data protection enthusiasts.

• FAQ

What people often ask Klaus.

When does the EU AI Act apply to me?

+
The prohibitions on unacceptable risk and the obligation to promote AI literacy in your team (Article 4) have applied since February 2025. Since August 2026, the transparency obligations under Article 50 have applied as well, for example for chatbots and deepfakes. The Digital Omnibus postponed the obligations for high-risk AI: from 2 December 2027 for systems under Annex III, from August 2028 for AI in regulated products. Klaus knows your deadline.

We "only" use ChatGPT. Do we even need Klaus?

+
Probably yes: as soon as you use ChatGPT in business processes, at least Article 4 (AI literacy in your team) applies, and you should keep an inventory of your AI applications. If you use ChatGPT directly with customers (e.g. as a chatbot or for automated replies), the transparency obligation under Article 50 applies as well. Klaus covers all of this in half an hour.

Does Klaus replace a lawyer?

+
No, and it is not meant to. Klaus covers 95% of the routine work: inventory, risk classification, standard documents, training. For genuine borderline cases (high-risk AI you develop yourself), Klaus puts you in touch with one of our partner lawyers.

How does this fit with the GDPR and Dieter?

+
Klaus and Dieter share the same login, account and master data. Wherever AI processes personal data (almost always), both sets of rules interlock: Klaus hands over to Dieter automatically and vice versa.

How much does Klaus cost?

+
As a solo freelancer with one employee and one AI system, you start completely free, with an AI policy and training. The 6-phase check of your AI systems is not included in the free plan; it starts with Klaus Basic. As your team grows, the price scales with your number of employees and AI systems: Klaus Basic from €29/month (up to 10 employees, up to 3 AI systems), Klaus Premium from €79/month (up to 20 employees, up to 10 AI systems), each with annual billing, excl. VAT. Beyond that, we will put together an individual Klaus Enterprise offer for you. The paid plans run for 12 months, then renew automatically for one further year at a time and can be cancelled with 3 months' notice before the end of the term.
