We fixed issues from the previous version.
Store description
Leksio gathers Polish court rulings, acts and tax interpretations from public registers in one place and names the source of every piece of information. Type a question, a provision or a case number, and Leksio will sniff out the documents that bear on your case.
The database already holds more than 1.2 million documents and keeps growing. Not every ruling is in it yet: Leksio adds them from the newest to ever older ones and files them by area of law.
English interface, Polish sources
The interface, Leksio reports, articles and questions and answers are in English. Rulings, acts and tax interpretations appear in their original Polish. Search works best with Polish queries.
Court rulings and tax interpretations
Leksio searches rulings of the Supreme Court, administrative and common courts, the Constitutional Tribunal, the National Appeals Chamber and the Court of Justice of the EU, plus tax interpretations from EUREKA and ZUS interpretations. Filter by court, year, document type or area of law, or keep only rulings with a thesis (key legal point). The reader shows the thesis, table of contents and cited provisions.
Acts and changes in the law
Read acts and regulations in their current wording and amendment history. Wording comparison shows word by word what was removed and added, and when the new version took effect. Leksio keeps watch over the acts you follow and emails you when their text changes.
Reports
Leksio reports show the law in numbers: divorces, child and spousal support, fines and more, with charts, a map of the voivodeships and the source of every figure. Selected reports are open without an account.
Leksio AI
Leksio AI summarizes the documents Leksio found, and every sentence has a numbered link to its source. It uses only those documents and never fills gaps with general knowledge. With SIP Pro+, an assistant also answers questions about the open document or act, with footnotes.
Before first use, Leksio asks for your consent. Query text and document excerpts are processed by an AI model in the EU region and are not used to train models. AI content is labeled “AI thesis,” “AI summary” or “Co-created with AI,” and AI answers can be reported in the app. AI can be wrong, so always check the source.
