ArsLex
ArsLex Associate, for Microsoft Word

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

Upload your case law, depositions, and pleadings. Drag in the passages that matter. ArsLex writes cite-anchored prose with Bluebook citations formatted automatically. It cites what you give it; it doesn't invent authority.

14-day free trial. Installs into Microsoft Word from AppSource.

The ArsLex add-in generating cite-anchored prose from a selected case, with long, short, and Id. citation options.
How it works

You bring the documents. ArsLex does the rest.

It works over your own evidence. It isn't legal research: it doesn't go find cases for you, and it never invents authority.

The moment you upload

Every document goes to work.

A case gets instant highlights and a star-paginated text view beside the original PDF. A deposition gets a digest at three levels with page-line citations. A complaint gets an allegation viewer and a Response Planner: Admit, Deny, or Partial, then a formatted Answer.

When you're ready to write

Outline in, cited draft out.

Drop the passages that matter into an outline. ArsLex drafts cite-anchored prose using your headings and prior writing as the prompt. Or drag any passage from the viewer straight into Word, and it lands with the citation already done.

Bluebook, automatically

Long form, short form, Id., pinpoints.

Every citation is formatted for your jurisdiction, with dual-reporter and parallel citations, even slip opinions. Search every document you've loaded in plain language.

Built around how litigators actually work.

Confidential by design

Your evidence stays yours.

Zero-retention AI: generation runs under terms where your content is never retained or used for training, and the embeddings behind search are computed on infrastructure we control. Encrypted in transit and at rest, isolated per firm, kept until you delete it, and gone when you do.
