The problem
Legal reasoning lives everywhere except in one place
Sources in one folder, facts in an email thread, arguments in your head, the chronology in a legacy Word table. Turning that into a pleading is the slowest part of the work.
The difference
They run the matter. LexProsa builds the work product inside it.
LexProsa is not practice management, not a search engine, and not an AI chatbot. It is the structured layer between your research and your drafting.
What LexProsa is not
Billing, intake, tasks, firm operations.
- — Not just search
- — Not just AI
- — Not law firm management
What LexProsa is
A structured legal work platform.
- · Source-to-argument workflow with strategic labels
- · Chronology and argument hierarchy, fully traceable
- · Conclusions, memos and analyses prepared from structure
Workflow
From raw materials to work product in four steps
1
Frame the matter
Define the issue, jurisdiction, objective and legal theme of the workspace.
2
Organize sources
Classify statutes, case law, exhibits and notes. Mark key, supporting and adverse authorities.
3
Structure reasoning
Build the chronology and the argument hierarchy — principal, subsidiary, responses to adverse points.
4
Prepare the output
Generate a conclusions, memo or consultation outline, traceable to its sources, and export it.
Features
Everything the reasoning needs. Nothing the back office wants.
Matter workspaces
Litigation, consultation, research and advisory workspaces with issue framing and status.
Source management
Fifteen source types, strategic labels, relations between authorities, pinned key sources, PDF and Word attachments.
Chronology builder
Factual and procedural timelines with events linked to sources and exhibits.
Argument builder
Principal, subsidiary and highly subsidiary arguments, admissibility and merits, adverse arguments and responses.
Traceability
Every argument shows its authorities and facts. Every output shows where it comes from.
Work product
Conclusions, memo, consultation and analysis outlines exported to lawyer-grade PDF and Word.
France-first, EU-aware
Built for multi-layer legal reasoning
French law and EU law are modeled as distinct legal layers, so an argument can rest on a code provision, an EU regulation and CJEU case law at once — and stay readable.
See it in practice
Watch a matter go from raw file to conclusions outline
The demo walks through a real litigation scenario: framing, sources, chronology, arguments, output.
Trust
Serious enough for an active matter
Confidential by structure
Private workspaces by default, role-based team access, and a clear separation between raw materials and structured work.
EU-hosted data
Database and document storage located in the European Union. Your matters do not travel.
Audit-friendly activity
Every meaningful action on a workspace is logged, so the history of the work is always available.
Structure the next matter properly, from the first source
