ArsLex
Litigation Intelligence

Draft litigation briefs grounded in your own evidence, with pin cites.

ArsLex Associate turns Microsoft Word into a litigation drafting workspace. Upload your case law, depositions, and pleadings; drag in the passages that matter; and ArsLex writes cite-anchored prose with Bluebook citations formatted automatically. It cites what you give it — it doesn't invent authority.

How it works

You bring the documents. ArsLex does the rest.

ArsLex works over your own evidence — the case law, depositions, and pleadings you already have. It isn't legal research: it doesn't go find cases for you, and it never invents authority. You upload, and it goes to work immediately.

The moment you upload

  • A case — instant highlights so you jump straight to the holding, and read it two ways: a clean text view or the original PDF, both star-paginated.
  • A deposition — an instant digest at three levels of granularity, with page-line citations.
  • A complaint — an interactive allegation viewer plus a Response Planner: mark each allegation Admit, Deny, or Partial and generate a formatted Answer.
  • All of it at once — search every document in plain language.

When you're ready to write

  • Drop the passages that matter into an outline — ArsLex drafts cite-anchored prose using your outline headings and prior writing as the prompt.
  • Every citation is formatted to Bluebook automatically — long form, short form, Id., pinpoints, even slip opinions.
  • Or drag any passage from the viewer straight into Word — it lands as text with the citation already done.
