Semantic Search and AI-Powered Case Law Engine
Find the Most Accurate Precedent Among 11+ Million Decisions in 2 Seconds
Traditional search engines understand keywords, Lextum understands legal issues. Our AI engine, which semantically analyzes decisions from the Court of Cassation, Council of State, Constitutional Court, and Regional Courts, reduces your research time by 80%, empowers freelance lawyers, and increases efficiency in corporate law firms.
Not Keyword Matching, Meaning Analysis
Lextum's semantic engine breaks down your sentence into concept maps and finds "similar legal events" in millions of case law decisions.
🧠 How AI Thinks?
When you type Refund due to latent defect in vehicle, the system automatically associates:
- 🔹 Code of Obligations 219–231 Defect Provisions
- 🔹 Court of Cassation's "elective rights" and "statute of limitations" decisions
- 🔹 Relevant Regional Court precedent decisions
Result: Precedent decisions that keyword-based search couldn't find, but which match your topic 100%, appear before you.

How Lextum Precedent Engine Works?
Semantic Analysis
Analyzes text not as words, but as legal meaning and context.
11M+ Scan
Scans all high court decisions in seconds.
Classification
Categorizes the decision by branch of law (Labor, Criminal, Commercial, etc.).
Event Detection
AI matches decisions closest to your event pattern.
Precedent Score
Assigns a 'relevance score' to each decision, moving the most relevant to the top.
Get the Best Efficiency from AI
For a good result, instead of asking a question, write the legal sentence or event you hope to find within the decision.
❌ Short and General Search
This search is too general. You will get lost among hundreds of thousands of results, and finding the decision that matches your specific event will take hours.
✅ Long and Targeted Search
This search tells the AI exactly what rationale you are looking for. The system moves precedent decisions closest to this sentence structure and meaning to the top.
Smart Matching Tip:
For example, when you search for "insult via phone messages"; Lextum finds decisions containing WhatsApp, Telegram or SMS even if 'phone' is not mentioned in the text. Because the system knows these are phone messages.
