Document Intelligence Hub
How we deployed an NLP-powered classification and extraction pipeline that tripled document throughput for a regional legal services provider.
Legal ServicesBillable hours lost to repetitive document review
Our client, a regional legal services provider with seventy-five attorneys across four offices, was spending an estimated twelve thousand billable hours per year on routine document review. Incoming filings, contracts, and regulatory submissions arrived in a mix of formats, including scanned PDFs, Word documents, and email attachments, requiring paralegals to manually read, categorize, and route each one to the appropriate practice group.
The volume was staggering. The firm processed an average of three hundred documents per business day, and the manual pipeline created bottlenecks that delayed client responses by an average of forty-eight hours. Senior partners were frustrated that highly trained attorneys spent hours on classification tasks that added no analytical value, and the firm was losing competitive bids partly because of slower turnaround times.
The firm had experimented with basic keyword search tools, but the nuance required for legal document classification, where a single clause can change the entire meaning and routing of a filing, demanded a more sophisticated approach. They engaged STC to design and deploy an intelligent document processing system that could handle the complexity of legal language while maintaining the accuracy standards their practice demanded.
Intelligent processing built on legal-domain expertise
OCR and Document Ingestion
We built a document ingestion layer that handles every format the firm encounters. Scanned documents pass through an advanced OCR engine optimized for legal typography, including dense multi-column layouts and handwritten annotations. The system extracts clean text with over ninety-eight percent character accuracy, then normalizes it into a structured representation that downstream models can process efficiently.
- Multi-format ingestion (PDF, DOCX, email, scans)
- 98%+ OCR accuracy on legal documents
- Automated metadata extraction and indexing
NLP Classification Engine
We fine-tuned large language models on the firm's own document corpus to classify filings into twenty-three practice-specific categories. The classifier achieves ninety-five percent accuracy on first pass, with a human-in-the-loop review step for edge cases that feeds corrections back into the model for continuous improvement.
Clause Extraction and Routing
The final layer uses LLM-powered extraction to identify key clauses such as indemnification terms, liability caps, termination conditions, and renewal dates. Each document is tagged with structured metadata and automatically routed to the appropriate attorney based on practice area, urgency, and current workload balance.
Transformative gains in speed and accuracy
The firm now processes three times the document volume with the same paralegal team, eliminating the backlog that had been building for years.
Attorneys and paralegals spend seventy percent less time on classification and routing tasks, redirecting those hours to substantive legal work.
Average response time to incoming filings dropped from forty-eight hours to under four hours, significantly improving client satisfaction.
Purpose-built for legal complexity
The document intelligence pipeline was designed with the unique demands of legal practice in mind. The OCR engine was calibrated specifically for legal document types, handling everything from court filings with numbered paragraphs to multi-party contracts with nested exhibit references. We implemented a confidence-scored output system where every extraction and classification decision comes with a transparency layer showing the model's reasoning.
The NLP classification models were fine-tuned using a curated training set assembled in collaboration with the firm's senior attorneys. Rather than relying on generic legal language models, we built domain-specific classifiers that understand the firm's particular practice terminology, filing conventions, and jurisdictional variations. The system supports continuous learning, automatically incorporating corrections from the human review loop into weekly model retraining cycles.
Integration with the firm's existing document management system was accomplished through a secure API layer that maintains full chain-of-custody tracking. Every document's journey, from ingestion through classification to attorney assignment, is logged with timestamps and audit trails that satisfy the firm's compliance requirements.
From bottleneck to competitive advantage
The Document Intelligence Hub did more than improve efficiency metrics. It fundamentally changed the firm's capacity model. With routine classification handled by the system, the firm was able to take on a significant number of new client engagements without hiring additional paralegals. The cost savings from reduced manual review have been substantial, while the faster turnaround has helped the firm win competitive pitches against larger rivals.
Perhaps most importantly, attorney morale improved measurably. Associates who previously dreaded document review rotations now spend that time on case strategy and client interaction. The firm's annual associate satisfaction survey showed a notable improvement in the first year after deployment, with respondents citing the reduced administrative burden as a top positive change.
"This system gave us back thousands of hours that we were spending on work no attorney went to law school to do. Our people are happier, our clients get faster answers, and we have scaled our practice without scaling our overhead. It is the kind of technology investment that pays for itself many times over."
