Most people sign a lease, a job offer or a parking ticket without ever reading the law behind it. This free, open-source library (past 1,800 GitHub stars) puts 306,000 real laws from 208 countries and territories on your computer, and plugs them into Claude, so you can ask in plain words and get the exact section back.

Here's what it does, how to set it up for your country, and what to ask first.

What it does

  • Finds the exact section of the law that answers your question, in the official text (nothing machine-translated).
  • Reads a law as it stood on any date, like the day you signed your lease.
  • Shows which law wrote each word, and what changed between two dates.
  • Checks a quote from a letter, a case or a brief against the law in force today.
  • Runs on your own computer with read-only tools and makes no network calls.
