Eulex
Eulex is an AI system for EU and Croatian regulation, built for legal professionals. It pairs a legal workdesk with an AI-ready corpus, answering with article-level citations that open on official portals, hosted entirely in the EU.
What is Eulex?
Eulex is an AI system dedicated to European regulation, published by Augment d.o.o., a Croatian company based in Zagreb. It comes as two distinct products. Eulex Desk is a workdesk for legal professionals: a conversational assistant that reads uploaded documents, quotes them verbatim with page and article numbers, and drafts or edits Word documents in tracked changes. Around the assistant sit Projects, per-matter workspaces that keep context across every conversation and document; Tabular review, which extracts data in parallel across hundreds of documents with each cell cited down to the page and passage; Workflows, tested prompts packaged as firm templates, of which 14 ship according to the FAQ; and Contexts, where the sources and working rules of a practice area are saved once and applied to each conversation. Eulex Base is the regulatory corpus behind it, structured for machine retrieval: 27,375 consolidated EU acts and 47,247 versions of Croatian regulation carrying in-force status. Retrieval happens at article level, with point-in-time views returning the text as it stood on a past date, and a citation graph following amendment chains, legal bases up to the treaties, and the link between a judgment and the act it concerns. The coverage matrix spans EU law (regulations, directives, treaties, implementing and delegated acts, CJEU and General Court), Croatia, Italy, Austria, France (marked New) and the ECHR, but unevenly. Answers cite official portals: EUR-Lex, Narodne novine, Légifrance, PISRS, Gesetze im Internet and the Official Gazette of the City of Zagreb. EUR-Lex and the national sources are re-ingested daily, amendments propagate through the graph and consolidated views are rebuilt. Indexing is in English, with original-language text fetched on demand through the CELEX identifier, while the homepage separately claims answers in 24 EU languages. A public MCP connector at mcp.eulex.ai exposes the public corpus over OAuth with no API key. Higher tiers add BYOK for Claude, OpenAI, Gemini or Mistral keys billed at cost, and a PII shield masking names, emails, phone numbers, addresses, payment cards, IBAN, Croatian OIB and MBS numbers and case references in three modes. The publisher names three Enterprise deployments in production, zginfo.ai, teb.hr and zakon.ai, and describes itself as fully self-funded with four co-founders.
What it does
- Ask a question in plain language and get an answer cited article by article
- Open each citation on its source, page and verbatim extract, with the in-force status shown
- Upload PDFs (with OCR for scans), .docx and .doc files, several at a time, into a matter project
- Extract data in parallel across hundreds of documents with Tabular review, every cell cited
- Draft and edit in tracked changes directly inside Microsoft Word through the add-in
- Mask personal data such as names, Croatian OIB, IBAN, MBS and case numbers before anything reaches the model
- Connect any MCP-compatible AI client to the regulatory corpus through mcp.eulex.ai
When to use Eulex / When not to
A quick filter to help you decide if Eulex is the right fit.
When to use Eulex
- Lawyers and in-house counsel working on EU and Croatian law who need every answer traced back to a specific article
- Contract review teams handling high-volume documents such as credit agreements, share purchase agreements and leases
- Due diligence teams running structured extraction across large document sets, where each cell of the review table carries its own citation
- Law firms wanting to standardise repeatable work into firm templates, using the 14 built-in workflows
- Builders of AI systems who need to ground their own products in primary European law through the MCP connector
- Organisations with strict GDPR requirements: built-in PII masking, EU hosting, a public DPA and a published subprocessor list
When not to use Eulex
- Consumers and private individuals: the terms and the privacy policy restrict the service to professionals acting in a professional capacity, aged 18 or over
- Anyone seeking legal advice: the publisher states explicitly that the output is not legal advice and that citations must be verified by a human before use
- Practitioners working outside the covered jurisdictions: coverage is limited to EU law plus Croatia, France, Austria, Italy, Germany, Slovenia and the ECHR, and it is uneven, with no consolidated or point-in-time layer for Italy, Austria or the ECHR
- Teams looking for a document management or contract lifecycle platform: the publisher states plainly that Eulex replaces neither a DMS, nor a CLM, nor firm email
- Teams of fewer than five people wanting a shared plan: Team and Legal Team require a minimum of five seats and are still marked Coming soon
How to use Eulex
A typical end-to-end flow, from setup to results.
- Create a free account on max.eulex.ai, with no credit card required
- Sign in through your Eulex account SSO, an emailed sign-in link or an 8-digit code sent by email; Google or LinkedIn SSO is also available
- Follow the four steps the publisher applies to every use case: ask, scope, verify, share
- Pick which corpora and connectors a conversation may query using the Context button, and save your own sets of sources and instructions as Contexts
- Create a Project per matter, upload the documents to it, and let the assistant keep context between conversations
- Turn web search on or off with the Prompt Navigator switch before sending a prompt
- Set masking in Account > Privacy & PII to Off, Standard or Strict; in Strict a review window appears before each model call and nothing leaves if the review cannot run
- Install the Microsoft Word add-in from a manifest.xml file and a six-digit pairing code, available from the Pro plan upward
- Import files from Google Drive, OneDrive or Box: a one-way copy is made at attachment time, with no later resynchronisation
- For an AI system, add the MCP server URL to the client configuration and call the search and retrieval tools; each result carries the article text, the act and its CELEX identifier
Pros & Cons
Pros
- Citations verifiable down to the page and the article, opening on official portals with the in-force status shown
- Consolidated corpus with point-in-time views and a citation graph, so the version in force on a past date can be retrieved
- Daily refresh of the corpus from EUR-Lex and the national sources
- EU hosting claimed and subprocessors published, with Vertex AI inference confined to the europe-west1 and europe-west4 endpoints
- No training on customer content unless the customer agrees in writing, and built-in masking with a strict mode that blocks if the review cannot run
- Permanent free plan with no credit card, MCP access included, and BYOK on the higher tiers giving extra AI capacity at cost
- Detailed public documentation (FAQ, billing, PII shield, integrations) and a complete legal stack online: terms, privacy policy, DPA, subprocessors and responsible disclosure
Cons
- Narrow geographic coverage: EU law plus Croatia, France, Austria, Italy, Germany, Slovenia and the ECHR, with empty columns on the matrix since Italy, Austria and the ECHR have no consolidated layer, no point-in-time and no citation graph
- The Desk interface and answers are Croatian and English, while the homepage advertises 24 EU languages; both claims sit on the site at the same time
- Team and Legal Team plans are shown as Coming soon and require a minimum of five seats
- Key features are reserved for higher tiers: masking and the Word add-in from Pro, BYOK and workflow-definition support from Legal Pro
- Daily usage limits apply on every plan including paid ones, at 5x, 20x and 80x the free tier, and prices exclude VAT with the annual discount limited to the Plus plan
- The PII shield does not cover Contexts, there is no mobile app, and no support email address is published, commercial contact going through a third-party booking calendar
- The privacy policy still describes payments as a future feature while the pricing page and the terms describe subscriptions billed through Stripe; the publisher is also young and small, self-funded with three employees according to the Croatian company register

Data, GDPR & hosting
A consolidated view of how Eulex handles your data.
GDPR overview
GDPR implementation is concrete and documented. The privacy policy, effective 5 June 2026, names its Article 6 legal bases: contract 6(1)(b), legitimate interest 6(1)(f), consent 6(1)(a) and legal obligation 6(1)(c). Section 2 separates the two roles, controller for the publisher's own purposes and processor for customer tenant data. Rights of access, rectification, erasure, restriction, portability, objection and withdrawal of consent are exercised at dpo@augment.hr, with a 30-day target response extendable to 60 days for complex cases, plus the right to complain to a supervisory authority. Storage and processing are intended to remain in the EEA, otherwise standard contractual clauses, an adequacy decision or supplementary measures apply. Security measures include encryption in transit and at rest, MFA for administrator access, environment segregation, access controls and logging. A public DPA dated 26 January 2026 gives 30 days' notice of new subprocessors. Established in Croatia, the publisher needs no Article 27 representative.
Who owns the data?
The customer keeps ownership of inputs and outputs. Clause 5.1 of the terms states that, as between the parties, you retain all rights you have in Customer Content, and clause 6.1 lets you use the Output for your internal professional purposes. The licence granted to Augment d.o.o. is narrow: hosting, storing, reproducing, transmitting and processing content only as needed to run the service, plus quality assurance and troubleshooting, the latter only if prompt logging is on. Augment retains the service, its documentation and the underlying technology (6.2) and takes a perpetual, irrevocable licence over feedback (6.3). Under the DPA, the customer is controller and Eulex processor.
Reuse rights
You may reuse your own material and the generated output for internal professional purposes without asking further permission, subject to the terms' professional-use restriction and to the publisher's warning that output is not legal advice and must be checked. On the publisher's side, the privacy policy lists the purposes in section 5: providing and operating the service, administering invitation and beta access, security and abuse prevention, improvement and diagnostics, support, and legal obligations. It states that personal data is neither sold nor used for consumer advertising profiling. Section 8.1 confirms that external AI providers generate answers and analyse documents, with minimisation and pseudonymisation where possible and contractual and technical controls limiting provider-side retention and training. Section 8.2 covers the Prompt Navigator: the service decides whether a web search is useful, the user sees a switch and can turn it off, and when it is on only an AI-rewritten, summarised query is sent. Section 8.3 states that prompt logging is off by default and only stores prompt and output logs once the user enables it. Clause 5.2 of the terms rules out training general-purpose models on Customer Content unless the customer expressly agrees in writing.
Data retention & training
Hosting summary
The publisher states that infrastructure runs on EU-region cloud services and that data does not leave the EU, a claim repeated on the homepage and the MCP connector page. Section 9 of the privacy policy is more nuanced: storage and processing are intended to take place in the EEA, but some providers may process outside it depending on their own infrastructure, notably for web search, analytics, monitoring and security. The published subprocessor list, dated 5 June 2026, names Google Cloud Platform, Brevo and Simple Analytics as core providers in the EU, and OpenAI with an EU endpoint, plus Exa and Tavily, as optional ones that may involve locations outside the EEA. Sections 6 and 12 of the DPA go further: Vertex AI inference on customer content is configured on an EU region endpoint, currently europe-west1 or europe-west4 or a successor EU region, and Google's global endpoint is excluded, with limited derogations for security, customer configuration or legal requirements. No individual hosting country is named, only the EU region.
Things to keep in mind
Risks and trade-offs to weigh before adopting Eulex.
- Output is not legal advice: the terms exclude it and require human verification of every citation before use, so treating a fluent answer as a finished opinion is the main risk of over-reliance
- Contractual liability is capped at EUR 1,000, Croatian law applies and the courts of Zagreb have exclusive jurisdiction
- Clause 4.4 of the terms mentions an early access phase in which certain features and security controls may be incomplete or unavailable, and the service may change or be discontinued
- The PII shield does not cover the instructions and source notes stored in a Context, which are sent to the model in clear
- With web search enabled, Exa and Tavily may process data outside the EEA; the Prompt Navigator switch allows it to be turned off
- Adding third-party MCP servers exposes the tools called, the queries and document extracts to their operator
- The ISO/IEC 27001 and 42001 badges shown on the publisher's site augment.hr are marked IN PROGRESS, are not obtained certifications and concern Augment rather than Eulex; separately, enabling prompt logging causes prompt and output logs to be stored for 30 days
Setup & Integrations
Technical difficulty
Basic setup is easy and requires no installation: a free account on max.eulex.ai without a credit card, then sign-in through account SSO, an emailed link or an 8-digit code, with Google or LinkedIn SSO available. Two steps are more technical: installing the Word add-in from a manifest.xml file and a six-digit pairing code, on Pro and above, and authorising the Drive, OneDrive or Box connectors once. Connecting an AI client means adding a URL and completing OAuth, with no API key for the public corpus. BYOK requires entering provider keys. Institutional and API access is negotiated, not self-service.

Should you pick Eulex?
Eulex is an unashamedly narrow tool. It targets EU and Croatian regulation rather than general-purpose assistance, and its value lies in traceability and freshness rather than in text generation: answers open on the article, the page and the official portal, and the corpus is re-ingested daily with consolidated and point-in-time views. For a lawyer who must be able to show where an answer comes from, that is a real difference from a general chatbot, which is precisely the comparison the publisher draws itself against ChatGPT and Microsoft Copilot. The privacy posture is unusually well documented for a company of this size: a public DPA, a dated subprocessor list, named EU inference endpoints, built-in masking with a blocking strict mode, and no training on customer content unless the customer agrees in writing. A compliance function will find most of what it needs already published. The reservations are just as real. Jurisdictional coverage is narrow and uneven, several countries lacking the consolidated and point-in-time layers. The publisher is young and small, incorporated in 2025 according to the Croatian register, three employees and fully self-funded, and the team plans are still marked Coming soon. The site also contradicts itself twice: the privacy policy still describes payments as a future feature while the pricing page lists seven priced tiers, and the homepage promises 24 EU languages while the FAQ and product pages describe a Croatian and English product. Neither point is disqualifying, but both deserve a question before signing. Trying it costs nothing, since the free plan is permanent, needs no credit card and already includes MCP access. The sensible approach is to run a real matter through it and check the citations by hand before committing to Plus at 24.00 EUR per month or above.
