Artificial Intelligence is transforming the legal profession, reshaping how firms are structured, how advice is delivered, and what clients now expect from their advisors.
What up until just recently required hours or days of manual research, can now be done in seconds.
At the same time, the roles within firms are evolving: junior lawyers face both new opportunities and risks, while senior lawyers must embrace agility, strategy, and trust-building as their true added value.
In this changing landscape, there is one reassurance: AI is not replacing lawyers and consultants. It is however reshaping the playing field and the winners will be those who see AI as more than a tool for efficiency and use it instead as a partner to sharpen their expertise, strengthen client trust, and deliver strategic value.
Creyten was built with exactly this philosophy in mind: an AI-powered partner designed to help legal and tax professionals cut through complexity and stay ahead . In this article, we will explain why Creyten works for you.
Creyten is built on the principle that no single method can answer every legal question with equal quality. Instead, it relies on what is known as a mixture of experts approach. At the heart of the system is an agent that evaluates each question and selects the tools needed to provide a complete and reliable answer. These tools mirror the categories of sources legal professionals already rely on. When the question is about legislation, Creyten draws from European law, treaties, federal laws, decrees, and implementing measures. When case law is needed, it can prioritize decisions from the European Court of Justice, the Constitutional Court, the Court of Cassation, and the courts of appeal. For administrative practice, it can integrate circulars, commentaries, parliamentary records or FAQs. And where relevant, it brings in administrative rulings and advance decisions.
This design means Creyten does not overwhelm the user with irrelevant information. Instead, it focuses only on the sources that matter for the specific question, keeping the answer both comprehensive and efficient. For lawyers and advisors, this feels intuitive because it reflects the way they structure their own research: selecting the right sources and ignoring the noise.
Finding the right documents and sources is only the beginning of legal research. True value comes from reasoning over those sources with the same priorities and nuances that lawyers apply in practice. This is where Creyten distinguishes itself.
The system respects the natural hierarchy of legal sources. Recent legislation takes precedence over older texts. Higher courts such as the Court of Cassation, the Constitutional Court, and the European Court of Justice carry more weight than lower courts. Administrative guidance is useful but always secondary to binding rules. This layered reasoning ensures that the answers provided are not only technically correct but also aligned with the way legal professionals argue and advise in practice.
Creyten also adapts to the specificities of different domains. Reasoning in tax law, for example, follows its own logic and traditions compared to company or contract law. The system is designed to reflect these differences so that its advice resonates with the professional experience of the user.
Every answer is anchored in traceability. Each conclusion is linked to the exact legal source, together with its context, so the professional can verify the reasoning and rely on it with confidence. This combination of hierarchy, domain awareness, and transparency makes Creyten stand out as a partner in legal reasoning rather than a simple search engine.
The strength of any legal research tool lies in the completeness of its sources. Today, Creyten already integrates the full Fisconet collection, which is the most authoritative and comprehensive body of Belgian fiscal law. This alone ensures that tax professionals never miss a critical law, case, or administrative guideline.
The ambition, however, extends well beyond Fisconet. Step by step, additional Belgian, European, and international sources are being added, enabling Creyten to become a truly exhaustive research assistant. This expansion will continue in the months ahead, and readers are invited to follow our blog for updates or to get in touch with our team to discuss their own specific needs.
In addition to public sources, Creyten offers something particularly valuable to professional users: the possibility to bring your own documents into the system. Legal doctrine, memos, and internal case notes can be uploaded and integrated with the public corpus. This means the advice generated is not only up to date and complete but also tailored to the unique knowledge base of the firm or organization.
The pace at which new legal sources appear is staggering. Laws, court decisions, and administrative documents are published every day, and clients expect advice with ever shorter turnaround times. Managing this flow of information is only possible with a system that combines completeness of sources with the ability to process them at speed.
By bringing together public law, private expertise, and the ability to keep up with daily change, Creyten makes legal research both broader and deeper, ensuring that professionals always work with the most relevant and complete set of information.
Behind every answer that Creyten delivers lies a highly sophisticated technological engine. Designing an AI system for legal research is not a matter of simply picking one model and letting it run. Each step in the process — from splitting legal texts into manageable pieces, to retrieving the most relevant passages, to choosing the right language model for reasoning — involves countless options. The combinations quickly become overwhelming, running into millions of possible configurations.
Creyten addresses this challenge with a pragmatic and systematic approach. Instead of relying on guesswork, the platform uses advanced optimization methods, such as genetic algorithms, to test and evaluate different setups. These methods allow the system to explore many alternatives in parallel and converge on the configurations that deliver the most reliable results for legal professionals. In practice, this means every parameter — from how texts are stored and retrieved, to how answers are generated — is fine-tuned to maximize both accuracy and consistency.
The speed at which new AI models and methods are released is staggering. What is considered state of the art today may be surpassed within weeks. Creyten is designed to keep pace with this reality. Its modular architecture allows new components to be tested rapidly against real legal questions. Only when measurable improvements are confirmed are they rolled into the production system, ensuring that users always benefit from the best available technology without disruption to their workflow.
This commitment to ongoing evaluation and improvement is not an abstract promise, but a daily practice. We document how Creyten is optimized and updated in detail in our dedicated blogpost, which you can read here.
In summary, Creyten is not just a tool that works well today, it is a platform built to remain state of the art tomorrow, continuously adapting to the evolving world of artificial intelligence while staying firmly anchored in legal expertise.
Legal professionals today work in an environment defined by complexity, speed, and constant change. Delivering advice that is complete, timely, and strategically valuable has never been more challenging and critical. Creyten was built to meet exactly that challenge.
By combining a mixture of experts with legal reasoning that mirrors the way professionals think, Creyten ensures that every answer is anchored in the right sources and aligned with legal practice. With comprehensive datasources that continue to expand and the ability to integrate proprietary documents, it guarantees completeness and relevance. And thanks to its state-of-the-art technology, Creyten evolves continuously, testing and adopting the best innovations in AI to remain a trusted partner over time.
For legal professionals, this means working with a research assistant that does not just keep up with the pace of change but actively helps them stay ahead of it. Creyten turns complexity into clarity, so that lawyers, tax advisors, and consultants can focus on what matters most: applying their expertise, building client trust, and delivering strategic value.
