Lexline
Built for litigators · Not for everyone

The litigation OS that shapes itself to your firm.

Upload pleadings, correspondence, discovery — anything. A document agent reads, indexes, and pulls every fact that matters. A second agent learns your firm's playbook and customizes the workspace around how you actually litigate.

§ 01 — Product

Every case lives in one room.
Ten stages, one continuous record.

From the first claim document to the last post-trial motion, your case moves through a single, structured pipeline. The agent watches the whole arc — so nothing falls between Discovery and Motions ever again.

01Always-on

Document Agent

Reads pleadings, correspondence, exhibits, deposition transcripts, expert reports — and extracts a structured fact sheet for every case. Cites every claim back to the source line.

02On-demand

Drafting Chatbot

Conversational. Feed it custom tasks: redraft this motion in our firm's voice, fold these facts into a demand letter, summarize today's correspondence. Templates learn from your edits.

03Customizable

Firm-shaped workspace

Connects to your DMS, billing, calendar, e-filing. Reshapes itself around your firm's stages, vocabulary, and workflows. Plaintiff shop and defense house don't need to look the same.

§ 03 — The agent

Two agents.
One reads. One writes.

Most legal AI tools are a single chatbot bolted onto a search box. Lexline is built around two specialized agents that do different jobs — and never get confused about which is which.

α
Document Agent
Strict, deterministic. Only reads. Pulls dates, parties, holdings, damages, citations. Refuses to draft. Refuses to opine.
β
Drafting Chatbot
Conversational. Redrafts in your firm's voice. Fills templates. Takes custom tasks. Cites back to facts the Document Agent already extracted.
Drafting chatbotgrounded in 41 docs
Redraft the demand letter using our firm's standard opener and the damages from Castaneda's medical records.

§ 04 — From the field
"We tried the big-name legal AI. It was a one-size-fits-all chatbot that didn't know a Rule 12(b)(6) from a Rule 26(f). Lexline shaped itself around how our PI shop actually moves a case — and the document agent caught a date discrepancy that would have cost us at trial."
