Terms of Use

Regumatrix (“the Service”, “we”, “us”) is a web application that helps individuals and organisations understand how Regulation (EU) 2024/1689 — the EU AI Act — may apply to an AI system they describe in plain text.

By creating an account or using any part of the Service, you (“User”, “you”) agree to be bound by these Terms of Use (“Terms”). If you do not agree, you must not use the Service.

We reserve the right to modify these Terms at any time. Continued use of the Service after a change constitutes your acceptance of the revised Terms.

We disclose the full technical pipeline below so you can make an informed judgement about how much weight to give the outputs.

2.1 Your input

You submit a plain-text description of your AI system (between 20 and 5,000 characters). You are responsible for the accuracy and completeness of this description. The quality of the analysis is directly dependent on the quality of what you provide.

2.2 Article retrieval

A deterministic keyword and semantic-matching module scans your description and selects up to 30 relevant articles and annexes from a structured JSON corpus of Regulation (EU) 2024/1689. This corpus encodes all 113 articles and all 13 annexes of the EU AI Act. The selected texts serve as grounding context for the AI model.

2.3 AI model generation

The retrieved article texts, together with a detailed legal-analytical system prompt, are submitted to a large language model (currently Google Gemini, provided via the Google AI API). The model returns a structured JSON output containing the following fields:

• Scope assessment (Article 2 and Article 3 territorial and definitional analysis)
• Risk classification (prohibited / high-risk / limited / GPAI / minimal) with reasoning
• Operator role determination (provider / deployer / importer / distributor)
• Applicable obligations — article-by-article list with conformity pathway
• Key compliance actions, ordered by urgency tier (Immediate / Pre-Market / Ongoing)
• Enforcement timeline with dates and in-force status
• Penalty exposure under Article 99
• Clarifications needed — missing information that would materially change the analysis
• GPAI systemic risk flag (where applicable)

2.4 Storage and PDF export

Each completed analysis is stored in your account history linked to your user profile. You may export any analysis as a PDF report at any time from your dashboard.

2.5 Inherent limitations

• Static corpus: The EU AI Act corpus in this tool reflects the text of Regulation (EU) 2024/1689 as published. Subsequent amendments, delegated acts, implementing acts, or guidance documents issued after our last update may not be reflected.
• AI model uncertainty: Large language models can misinterpret, omit, or hallucinate legal content. Every output, however well-grounded, should be treated as a starting point for professional legal review — not a definitive compliance determination.
• Description dependency: The system has no access to your actual codebase, training data, deployment configuration, or contracts. It analyses only the description you provide. An incomplete or inaccurate description will produce an incomplete or inaccurate analysis.
• Jurisdiction specifics: The EU AI Act requires Member State implementing legislation for certain provisions (notably penalties under Article 99). National variations are outside the scope of this tool.

The Service does not provide legal advice. Full stop.

Every analysis output contains a mandatory disclaimer to this effect. Nothing produced by the Service — including any assessment of risk classification, applicable obligations, penalty exposure, or conformity pathway — constitutes legal advice, legal opinion, or a lawyer’s professional judgement. No solicitor–client or attorney–client relationship is formed by your use of the Service.

You should engage qualified legal counsel with expertise in EU AI regulation before making compliance decisions, submitting regulatory filings, signing EU Declarations of Conformity, or relying on any analysis produced by this tool for commercial or operational purposes.

We accept no liability for any loss, penalty, regulatory enforcement action, or other consequence arising from your reliance on outputs generated by this Service.

Account creation and authentication are managed by Clerk, Inc. You must provide accurate information when registering. You are responsible for maintaining the security of your account credentials.

Each new account receives 3 free analysis credits upon registration. Each compliance analysis consumes 1 credit. Credits purchased in a pack never expire and are non-transferable between accounts.

We impose rate limits to protect service quality. A maximum of 5 analysis requests may be submitted within a rolling rate-limit window per account. Exceeding this limit will temporarily block further requests; the exact window duration is shown in the error response.

Credit packs are available for one-time purchase through PayPal. Prices at the time of writing are:

• Starter — 10 credits for USD 9.00 (USD 0.90 per analysis)
• Growth — 40 credits for USD 29.00 (USD 0.73 per analysis)
• Pro — 120 credits for USD 79.00 (USD 0.66 per analysis)

All prices are in US Dollars and are exclusive of any applicable taxes. You are responsible for any taxes levied on your purchase by your local jurisdiction.

Refund policy: Because credits are a digital good consumed immediately upon use, all purchases are final and non-refundable once credits have been applied to your account. If a technical failure results in a credit being deducted without a completed analysis, please contact us and we will restore the credit.

We reserve the right to change pricing at any time. Price changes do not affect credits already purchased.

You agree not to use the Service to:

• Submit descriptions that contain personally identifiable information about third parties without their consent
• Attempt to reverse-engineer, scrape, or systematically extract the EU AI Act corpus, system prompt, or model outputs at scale
• Circumvent rate limits, credit checks, or authentication controls through automated means
• Use the Service for any purpose that is unlawful or that infringes the rights of others
• Represent AI-generated outputs as the opinion or advice of a qualified lawyer to third parties
• Resell individual analysis outputs as standalone legal opinions or compliance certificates

We reserve the right to suspend or terminate accounts that breach these restrictions without prior notice.

7.1 The EU AI Act text

The text of Regulation (EU) 2024/1689 is a public act of the European Union and is reproduced here for informational and educational purposes under the rules applicable to EU publications. The European Union retains all applicable rights in the official regulation text. A link to the official EUR-Lex publication is always available in the Service navigation.

7.2 The Service and its outputs

The software, design, system prompts, retrieval logic, and all other proprietary components of the Service are our intellectual property. You may not copy, redistribute, or create derivative works from these components.

Analysis outputs generated for your account are provided for your personal or internal business use. You may share, export, or include them in internal compliance documentation. You may not commercialise individual analysis outputs (e.g. by reselling them as legal reports to third parties).

7.3 Your descriptions

You retain all rights in the system descriptions you submit. By submitting a description, you grant us a limited licence to process it for the sole purpose of generating your analysis and storing the result in your account history.

The following data is stored in association with your account as a direct consequence of using the Service:

• Your Clerk user profile: user ID, email address, first and last name (if provided), and profile image URL
• Each description you submit (stored verbatim as plain text)
• The full structured analysis result for each submission (stored as JSON, including all output fields listed in Section 2.3)
• Metadata per analysis: risk classification, operator role, articles referenced, credits used, and submission timestamp
• Transaction records for credit pack purchases: PayPal order ID, pack name, amount, credit count, and payment status
• A credit audit ledger recording every credit addition (sign-up, purchase) and deduction (analysis run)

We do not sell your data to third parties. Your descriptions are not used to train or fine-tune AI models. We do not share your analysis history with any third party except as required by law or as expressly necessary to operate the Service (e.g. the AI model API receives your description and retrieved article text to generate the analysis).

A full Privacy Policy will be published separately and will govern data handling, retention periods, your rights under applicable data protection law, and cookie use. Please check back for its publication.

The Service is provided “as is” and “as available” without warranties of any kind, express or implied, including but not limited to warranties of accuracy, fitness for a particular purpose, or non-infringement.

We do not warrant that:

• Analyses will be error-free, complete, or up to date with the latest regulatory guidance
• The Service will be uninterrupted or available at all times
• The AI model will correctly interpret every factual scenario
• Outputs will meet your specific compliance requirements

To the maximum extent permitted by applicable law, our total liability to you for any claim arising out of or relating to these Terms or your use of the Service shall not exceed the total amount you paid to us in the twelve months preceding the claim. In no event shall we be liable for any indirect, consequential, incidental, special, or punitive damages, including lost profits or regulatory penalties.

Some jurisdictions do not allow the exclusion or limitation of certain warranties or liabilities. In such jurisdictions, our liability is limited to the minimum extent permitted by law.

You may delete your account at any time through your account settings. Upon deletion, your profile and analysis history will be permanently removed from our active database. Remaining unused credits are forfeited upon account deletion and will not be refunded.

We may suspend or terminate your account without notice if you breach these Terms, engage in fraudulent activity, or if we are required to do so by law. In the event of wrongful termination by us, your sole remedy shall be a pro-rata refund of unused credits.

We may update these Terms at any time. Material changes will be notified through the Service interface or by email to your registered address. The “Last updated” date at the top of this page reflects the most recent revision. Your continued use of the Service after notification constitutes your acceptance of the updated Terms.

These Terms shall be governed by and construed in accordance with the laws of Ireland, without regard to its conflict of law principles. Any disputes arising under these Terms shall be subject to the exclusive jurisdiction of the courts of that jurisdiction.

If you are a consumer located in the European Union, you may also have rights under the mandatory consumer protection laws of your country of residence, which these Terms do not override.
