01 / The Challenge

The firm faced operational bottlenecks: lawyers spent up to 4 hours manually drafting petitions and contracts. Manual searches for case law and updates consumed time that should have gone toward strategic analysis, and the lack of standardization led to inconsistent document quality and legal risks.

”— NOTA DE CAMPO
“The excess of manual work on legal documents was preventing the firm's strategic growth.”
02 / The Solution

We structured a vector knowledge base from historical contracts, petitions, and appeals, integrated with jurisprudence databases via API for automatic referencing. A conversational agent allows lawyers to request documents, adjust clauses, and refine text in real-time via chat—featuring a feedback loop that continuously improves future generations.
