Litigators on Demur
What litigators told us.
0103
“Live deposition assistance is something we’ve been talking about for a long time. I think it would be something litigators would find really, really compelling—something Harvey doesn’t do.”
The deposition ends. The consequence does not.
Finding it later does not give you the moment back.
The expensive miss is rarely that the fact was impossible to find. It is that the answer changed the case and no one carried the consequence forward before the useful window closed.
02
The record stays missing
A new provider or document is named, but the request never reaches the next round of work.
03
The stale theory travels
An expert, pleading, or motion is built on the case as it looked before the answer changed it.
The useful window can be minutes.Catch it live. Carry it through.
One answer, every consequence
Watch one answer move through the case.
Demur keeps the live answer, the legal issue it changes, counsel’s decision, and the work that follows on one continuous thread.

Built for the lawyer running the case
For litigators who cannot afford to find it late.
Demur keeps the record, contradictions, open proof, and next moves together—tuned to the practice, the side, and the lawyer responsible for what happens next.
Built for consequential work
Every suggestion starts with the exact source.
Demur keeps the source, its legal status, and counsel's decision visible from the first live flag through the last piece of work.
The exact source stays attached
Open the page or testimony behind a change with the speaker, document type, and status intact.
Legal status stays distinct
An allegation, denial, medical entry, expert opinion, and ruling never collapse into the same kind of fact.
Counsel makes every material call
Demur proposes what changed and what follows. The responsible lawyer decides what belongs in the case.
Matter data stays confidential
Data is encrypted at rest and in transit and is not used to train models unless separately agreed in writing.
Questions and answers
What Demur does—and what counsel controls.
The lawyer owns judgment and strategy. Demur owns keeping the live answer connected to the work counsel can still do.
01What does Demur do during a deposition?
Demur follows testimony against counsel's objectives and selected case materials. It surfaces incomplete answers and cited conflicts while the witness can still respond, then keeps the work created by that answer in view after the deposition.
02How is Demur different from a legal chatbot?
A chatbot waits for a prompt and returns a task. Demur participates in the authorized live proceeding, notices the material answer, shows the exact basis, and keeps the approved consequence connected to the work that follows.
03How is this different from a chronology or case management system?
A chronology records what happened. A case management system tracks documents, tasks, and deadlines. Demur shows what a new development changes in the legal case, which useful moves remain open, and whether counsel chose to pursue, defer, or waive them.
04Where is Demur available today?
Demur is live in depositions today. The broader follow-through across record review, discovery, pleadings, experts, and trial is available through a limited design-partner program.
05Does Demur replace attorney judgment?
No. Demur identifies the change, keeps the source attached, and prepares the available next moves. Counsel decides what the evidence means and what action belongs in the case.
06Is Demur always recording?
No. Counsel starts, pauses, and ends each authorized live deposition. Live listening runs only when counsel enables it under the firm's protocol and applicable notice requirements.
