Why Legal Teams Need AI for Document Review
In high-stakes legal work, every minute spent sifting through contracts, compliance documents, or case law is time away from strategy, client advising, and winning cases. Manual reviews drain billable hours, increase error risks, and expose sensitive data to cloud vulnerabilities. AI for legal documents changes this by accelerating analysis while maintaining ironclad security.
AirgapAI empowers your team with on-device processing of your private repository, turning overwhelming document volumes into actionable insights. This calculator reveals the hidden cost of current workflows and quantifies the freedom gained from faster, more accurate reviews.

How to Use This Legal Document Review Calculator
- Define Your Team: Enter the number of legal professionals involved in reviews—attorneys, paralegals, and compliance staff—to scale the impact accurately.
- Assess Current Workload: Input average weekly hours spent on document analysis and your manual throughput rate. This establishes the baseline for time-intensive tasks like contract drafting reviews or regulatory filings.
- Factor in Errors: Estimate your current error rate from rework or missed clauses. Legal errors can cascade into major liabilities, so accuracy is paramount.
- Set Financial Context: Provide your average billable rate to translate time savings into revenue potential or cost reductions for in-house teams.
- Project Forward: Choose an analysis period (e.g., 6-24 months) to see cumulative benefits, aligning with billing cycles or fiscal planning.
Pro Tip: For firms with variable workloads, run scenarios for peak litigation periods versus routine compliance to uncover peak efficiency gains.
Calculation Methodology
This calculator models time savings based on established benchmarks for AI-assisted legal workflows, focusing on processing speed and error reduction without compromising security.
Core Formulas
AI Throughput = Manual Docs/Hour × 1.4 (40% Faster)
Time Saved (Processing) = Manual Hours × (1 - 1/1.4)
AI Error Rate = Current Error Rate / 78
Error Savings = (Manual Rework Hours - AI Rework Hours) × Period
Total Hours Saved = Processing Savings + Error Savings
Financial Value = Total Hours Saved × Billable Rate
