02Agentic Review Suite

Hand off the work. Not the decisions.

Search, tag and organize a collection, then hand the work to the agent. It plans before it acts, asks before anything changes, and writes down the reason for every call it makes.

  • Search, Tagging & Binders
  • Search Term Reports
  • Batch Review & AI First Pass
  • Redactions & Privilege Logs
  • Step-By-Step Productions

Marbury AgentNew chat

Tell the agent what you want done. It comes back with a plan, and nothing runs until you approve it.

Pull the files Kessler opened in his exit window into a binder for the TRO motion, and save the search.

Notes from building Marbury.

The problems in discovery we set out to fix, and how the platform fixes them.

Clearwell proved you should own processing.

An appliance took control of processing sixteen years ago and sold for $392 million. What it proved, where it fell short, and what has since changed.

What you pay before anyone reads a document

A real eDiscovery rate card has a dozen meters running before review starts. Here is one, line by line, added up for a small matter, and what Marbury does about it.

Negotiate search terms with numbers the other side can rerun

Courts have asked parties to show their search work since 2008. A term report is how you show it, and how you win the negotiation.

The privilege log is a query, not a document

Rule 26(b)(5)(A) never says the word log. It asks that the other side be able to assess the claim. Marbury treats the log as the answer to a question you ask once.

FAQ

01What is Marbury?

Marbury is an eDiscovery platform powered by agentic and generative AI. The Data Processing Engine handles ingestion and processing, and the Agentic Review Suite handles document review. Both live in one workspace, and anything you process can be exported to any other eDiscovery platform, so you are never locked in.

02Who is it for?

Legal teams with the volume to own processing: in-house departments, BigLaw, boutique and midsize firms, litigation support and insurance carriers. See the Solutions.

03Who is behind Marbury?

Experienced lawyers and lead Google engineers, in Seattle. Meet the founding team.

04Is my data used to train AI models?

No. We have a strict no-training policy. Our upstream AI providers operate under zero data retention agreements and are contractually prohibited from using your data for training. How we handle your data.

05How long does it take to learn?

Minutes. If you can use a search bar and a chat window, you can use Marbury. There’s no complex certification, multi-day training, or IT setup required.
