The challenge
A representative corporate legal team reviews a high volume of third-party paper, and the first pass is the bottleneck.
Manual first-pass review is slowest exactly when it matters most — during diligence, when volume spikes and deadlines do not move. Deloitte's benchmark for intelligent document processing in finance is 60-80% less processing time and 50-70% lower cost, with extraction accuracy commonly reported in the 90-99% band and heavily workload-dependent.
The risk in this scenario is not throughput alone. It is a missed clause in a long agreement, which is what a consistent, auditable first pass is meant to prevent.
- Setting
- Representative — corporate legal
- System concept
- DocuMind
- Illustrative duration
- 14 weeks
The architecture
We deploy DocuMind against the legal team's own document management system. Extraction and clause models are tuned and evaluated on the client's own historical corpus under a signed data agreement and validated against senior attorney review. The system produces a structured first pass — parties, dates, obligations, and deviations from the client's standard positions — with every extracted field linked back to its source span, so a reviewer can verify it in one click. Risk flags are ranked for attorney attention; the system does not approve, sign, or advise.
Ingestion Agent
Accepts contracts in PDF, Word, and scanned formats, performing OCR where needed
Extraction Agent
Identifies key clauses, dates, parties, and obligations, linking each field to its source span
Analysis Agent
Compares against the client's standard positions and surfaces deviations
Compliance Agent
Checks against the client's own policy set and the regulatory requirements in scope
Output Agent
Generates the structured summary and a ranked risk list for attorney review
A proposed delivery path
This sequence illustrates the engagement. The actual scope, timeline and quotation are agreed around your requirements.
Legal Domain Assessment
Analyzed contract types with the legal team, defined the extraction taxonomy and the client's standard positions
Architecture Design
Designed the multi-agent pipeline, the source-linking model, and the attorney review workflow
Build & Evaluation
Built the agents and tuned and evaluated extraction on the client's own historical corpus under a signed data agreement, validated against senior attorney review
Integration
Integrated with the document management and matter management systems, with access controls mapped to existing roles
Handover & Rollout
Phased rollout with an operator runbook, review-workflow training, and a documented rollback path

What the scope can include
- Extraction and analysis agents running against your own document management system
- Clause taxonomy and standard-position library built with your legal team
- Evaluation report scoring extraction against senior attorney review, per contract type
- Source-linked review interface, access controls mapped to existing roles, and an operator runbook
- All source code in your repository, with the deployment owned by your team
Where people stay in control
- The system produces a first pass. Attorneys make every call — nothing is approved, signed, or advised by an agent.
- Every extracted field links to its source span in the original document, so no output has to be taken on trust.
- Accuracy is stated as a published ceiling, not a commitment; your own evaluation against attorney review sets the operating threshold.
- Client documents stay inside the environment named in the data agreement and are not used to train shared models.
Sources behind the scenario
- IDP: 60-80% less processing time, 50-70% lower cost
Deloitte - Extraction accuracy up to ~99%, commonly 90-99% and workload-dependent
