Built from the ground up by attorneys, for attorneys

You practice law. DuraLex runs the practice.

One system for the whole firm, in every area of law. DuraLex reads every notice and document, records each fact with its page and hands the work to the right person, for the attorney to approve.

What your clients see, in their own language.

Two sample cases in five languages. Open the case file and read the court papers, the receipts and the green card details, then see the dates, the documents to sign and the balance. This is a preview: buttons show what they do, and nothing is booked, signed, paid, sent or downloaded. Everything here is made up.

How DuraLex checks the work

Every fact checked. Every date on one timeline.

Errors are caught before a document reaches the attorney, and every deadline has an owner until it is done. Items marked planned are on the roadmap; paid or approval-based sources are added only after an agreement is signed.

What gets checked

Legal checksTwo of three run in our firm today

Case treatment, each citation against the court record, and every quotation word for word, by independent third-party verification providers.

MidpageCourtListenerDescrybe
Medical checksPlanned

Diagnosis codes against the current ICD-10-CM set from the CDC and CMS, providers against the NPPES NPI Registry, medications against RxNorm and FDA labels, studies against PubMed.

Law text checksPlanned

Statutes against the U.S. Code on GovInfo, regulations against the current eCFR and the Federal Register, and bills against Congress.gov, word for word.

Error logPlanned

When built, every flag will be assigned, tracked with reminders and kept until an attorney resolves it, with a record of what was checked, by whom and when.

Keeping every timeline

  1. Dates read from every documentIn build

    Each date is recorded with its page and placed on one matter timeline.

  2. Conflicts flaggedPlanned

    An entry date that differs between the I-94 and the asylum application, treatment recorded before the accident, or a hearing date that does not match the court notice.

  3. Deadlines from the rulesPlanned

    Court-rules deadlines through a licensed rules engine, for the attorney to confirm.

  4. Agency and court statusPlanned

    USCIS case status only through an official USCIS interface, with any required authorization; federal dockets on the firm's own PACER account.

  5. Owners and remindersIn build

    Each deadline goes to a team member and a reviewing attorney, with reminders before it is due; overdue work stays flagged.

Why DuraLex

The four things a practice runs on.

Verification.

Every citation and quotation is checked by independent third-party providers, and every fact shows the page it came from. Nothing is filed or sent until the attorney approves it.

Getting paid.

Invoices go to the client from the matter. When a payment comes in, it is applied to the right client account and the balance updates. Automatic payment matching is a coming feature.

Assignment of matters.

Each matter and task has a named staff member, a reviewing attorney, a due date and a follow-up. The attorney sees who has what, and what is late.

Calendaring.

Court notices become hearings and deadlines on the right matter, on the right person's calendar. Deadlines are suggested under the rules and confirmed by the attorney.

Questions

What firms ask first.

Does the AI make decisions on its own?

No. AI supports your legal knowledge; it never substitutes for it. Every fact shows its source and page, and nothing enters the record or goes to a client until an attorney approves it.

Where are my firm's files kept?

In your firm's own cloud storage. DuraLex organizes and reads the files where they are.

Is DuraLex quantum-safe?

Post-quantum protection is a coming feature. When enabled, connections to DuraLex will use hybrid post-quantum encryption following the NIST standards published in August 2024.

Can we text clients from our own number?

That is a coming feature, through business phone systems such as RingCentral, Quo, Dialpad and Zoom Phone, or Twilio for a number you already have. Texting is for client communication only.

Can we move over from our current system?

Yes. Early-access firms have their data moved over at no charge.

Early access

Built inside a working law firm, for firms of every size and practice.

We are inviting a small group of firms to join as design partners, with founding-firm pricing in exchange for feedback.

For investors. DuraLex runs today inside a working law firm, and we welcome conversations with investors who want to help bring it to firms across the country. This is not an offer to sell, or a solicitation of an offer to buy, any security.
