Media about us
Discover the capabilities of a platform that analyzes documents, organizes sources, and supports the daily work of law firms and legal departments
Autonomous AI Trainee
Agent Gaius acts like a Junior Associate: breaks down topics into stages, searches sources, and organizes conclusions.
Working with current Polish law
The Agent analyzes based on a daily updated database including laws, case law, and the Eureka database. It understands the Polish hierarchy of legal sources and the specifics of a lawyer's work in the Polish system.
Analysis of your own documents
You can securely add your own files to the system, and the Agent will include them in the analysis. Your data remains under your control - the model does not learn on your organization's documents.
Creating ready drafts of documents
Gaius-Lex doesn't stop at the answer. It prepares drafts of pleadings, responses, client emails, and comparison tables, allowing the team to move faster from analysis to action.
Protecting sensitive data and support in anonymization
The system helps detect and anonymize sensitive data in documents. Everything runs in a secure EEA infrastructure or in an on-premise deployment, according to the organization's requirements.
Verification of sources instead of guessing
Every legal thesis can be annotated with a footnote and a link to the source. The system checks the existence of signatures and documents in the database, and when there's no confirmation, it doesn't pretend to be sure.
Agent Gaius
How Gaius-Lex does legal research
Analyzes legal acts, jurisprudence, and documents in one coherent environment.
Indicates specific legal bases, quotes, and case signatures, making it easier to justify your position.
Takes into account both public sources of law and internal organization documents, so it works in the real context of the case.
Helps reduce the risk of errors and omissions by organizing legal material and pointing out what's truly important.
Automatically extracts key theses from your documents, compares them with jurisprudence, doctrine, and other sources, and shows which are well-justified and which need strengthening.
Deep Research enables searching for all court rulings meeting specified, even the most advanced criteria, and presents the results in a clear tabular form.
Work precisely and faster. Gaius will be your partner helping you build a lasting advantage
Answers you can trust
Each analysis includes full and precise sources: articles of acts, case signatures, and legal bases. You always know where each thesis comes from.
Real time savings
Gaius-Lex eliminates manual searching of databases, commentaries, and rulings. Instead of hours of research - a clear answer in a few minutes.
Working on your documents
Upload a contract, regulations, or pleading, and the system will identify risks and gaps, point out the correct legal context, and link the document with current jurisprudence. Upload PDF, DOCX, images, or recordings - we'll perform OCR and transcription automatically.
Data security
Data processing entirely within the EU. Data encryption compliant with legal sector standards. No training of AI models on your documents.
Law is not a place for AI guessing
| With Gaius-Lex | With general models (e.g., ChatGPT) |
|---|---|
No guessing: thesis + footnote + link to regulation or ruling. Signatures are verified. | Risk of hallucinations: the model can make up rulings and regulations, sounding very convincing. |
State as of today: legal database updated daily. | Knowledge up to training date: changes that came into force yesterday might not exist in the model. |
Confidentiality: data encrypted, stored in EEA, and not used for training public models. | Depends on provider and settings: often a lack of clear control over cloud processing. |
Autonomous Agent: you commission the goal, the system plans research, searches sources, and compiles the result. | Manual control: you guide step by step; with longer analysis, the risk of losing the thread increases. |
Polish and European law: hierarchy of sources, jurisprudence practice, and the reality of a lawyer's work. | General model: sometimes mixes legal systems and applies US/UK logic to Polish ground. |
