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.
Built around how litigators actually work

ArsLex Discovery Suite: run discovery in-house.
Alongside the drafting workspace, ArsLex is a full, end-to-end eDiscovery platform your firm can run itself: the same category of tool firms license for review and production, on the same zero-retention AI foundation. Ingest, review and code, redact, number, log privilege, and produce, all in one place, with the working copy of your production kept live and searchable.
Ingest & load files
Bring in native files and existing productions. Load-file import and export are compatible with the DAT and OPT formats used by Relativity and Concordance, so data moves both ways. Custodian is captured at the door, and anything that would not process is listed as an exception you can see rather than a document that quietly came in empty.
Review, batches & bulk coding
Code for responsiveness, privilege, and confidentiality from assigned batches, by keyboard at the desk or by swipe on a phone. Code a whole search result at once after a preview that shows what will change and where the AI reads the record differently, and undo the whole gesture in one action if it comes out wrong.
Threads, clusters & concept search
Read the emails that carry the whole conversation instead of the same quoted text nine times. Group a production by subject, flag near-duplicates, and search by concept as well as by keyword.
Bates, redactions & productions
Bates numbering with families kept in one range and a gap check before you certify it, redactions, and privilege logs, then produce with a load file for opposing counsel. Mark it served and the set freezes, so the record still matches the certificate months later.
Reports you can hand a court
Search-term reports for the meet-and-confer, statistical validation sampling, personal identifier scanning, a privilege log and counsel roster, Bates gap checks, and exhibit lists. Reviewer QC sampling states in words how the sample was drawn, so the check can be reproduced.
Custody, holds & clawback
Legal holds that suspend deletion, per-matter hosting that keeps closed matters in a warm archive rather than cold storage, and clawback in both directions, including an inbound notice entered by Bates range that pulls the matching documents out of review and export.

Your evidence stays yours.
Zero-retention AI. Text generation runs on Amazon Bedrock under AWS's zero-data-retention and zero-operator-access terms: never used to train models, never retained by the AI provider, and the embeddings behind search are computed on infrastructure we control and never leave it. Encrypted custody. Everything is encrypted in transit and at rest, isolated per tenant, and backed up nightly, and a firm can ask for its documents to be sealed under an encryption key of its own. Provable deletion. We keep your work until you delete it, and when you delete it, it is gone, with a written account of what that means and how long it takes.
