What is 圆周律πLex?
πLex helps you with legal work: a full‑scenario, on‑premises legal AI workstation. Simply upload your documents, clarify the facts, and deliver the final draft—useful for everything from litigation to non‑litigation matters, and suitable for law firms and corporations alike. It’s the perfect partner for every legal professional.
Key features
Read the document once, arrange the dates and events in chronological order, and mark any missing sections; extract the amounts, dates, and interest rates into a table, and cross-check them against the original.
The statutory provisions and similar cases it cites can all be accessed directly to view the original text; statutory references are not stored in the model’s memory—instead, they are retrieved on demand from the legal database and matched item by item. Similarly, analogous cases are pulled live from the case database, complete with case numbers. By clicking the footnote icon, users can see a side-by-side comparison between the AI-generated citation and the official original text; if the two match, the footnote is labeled “Verified”; if they don’t, the discrepancy is flagged immediately.
