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 holds more than 1.2 million documents and keeps growing. Leksio adds rulings from the newest to ever older ones and files them by area of law. After you sign up, a short tutorial shows where the sections, search, filters and your account are.
English interface, Polish sources
The interface, reports, articles and Q&A are in English. Rulings, acts and tax interpretations stay in Polish, and 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. The reader shows the thesis, table of contents and cited provisions.
Acts and changes in the law
Read acts and regulations from the Journal of Laws and Monitor Polski in their current wording, with amendment history. Wording comparison shows word by word what was removed and added. 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 support, fines and more, with charts, a map of the voivodeships and the source of every figure. All reports are open without an account, and each one has its own link to share.
Leksio AI
Leksio AI summarizes the documents Leksio found, and every sentence links to its source. It uses only those documents. With SIP Pro+, an assistant also answers questions about the open document, with footnotes.
Before first use, Leksio asks for your consent. Queries 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 check the source.
Services: court substitutions
Verified advocates, attorneys-at-law and trainees hand off single tasks to each other: appearing at a hearing or a public office, or reviewing case files. The date, fee, instructions and chat sit in one place, and notifications flag the next step. You can block anyone you don't want to work with. The section is free; Leksio checks the professional register and doesn't handle payments.
Your library
Save documents in folders, add notes and download them to read offline. On iPad, the list and the document sit side by side.
