Why AI for Legal Discovery is Revolutionizing e-Discovery Costs
In high-stakes litigation and investigations, e-discovery can devour budgets and timelines. Traditional vendors charge $75-200 per hour for armies of reviewers sifting through mountains of documents, creating privilege logs, and flagging key evidence—all while exposing sensitive data to third parties. But what if your legal team could handle it faster, cheaper, and more securely?
AirgapAI changes the game for AI for legal discovery by running entirely on-device. Legal professionals use it to accelerate document review, automate privilege tagging, and identify critical documents with 78X greater accuracy from curated datasets—all without sending data to the cloud. This calculator reveals the hard numbers: expect 40-60% cost reductions, smaller external teams, and ironclad protection of attorney-client privilege.

Analysis Parameters
How to Use This Legal Discovery Cost Calculator
- Define Your Dataset: Enter the total number of documents and average pages per document. This sets the scale for your e-discovery project, whether it's emails in a merger dispute or PDFs in regulatory probes.
- Input Traditional Costs: Specify the hourly rate for contract reviewers ($75-200) and time per page (typically 0.25-1 minute). These reflect vendor quotes for manual review without AI assistance.
- Configure AirgapAI Setup: Add the number of users on your team and the one-time perpetual license cost per device. Volume scaling lowers effective costs for larger firms.
- Adjust AI Efficiency: Set reduced review time per page (aim for 40-60% faster, e.g., 0.1-0.3 minutes) based on AirgapAI's on-device acceleration for legal workflows.
- Account for Specialized Tasks: Estimate privilege log complexity (entries per 1,000 pages) to quantify automation gains in tagging and logging sensitive materials.
- Select Project Timeline: Choose months to analyze team sizing and total costs, matching your litigation schedule for realistic FTE reductions.
Pro Tip: Run scenarios with conservative (40%) and optimistic (60%) efficiency gains to build a compelling business case for partners or clients. Focus on how AI for legal discovery keeps control in-house.
e-Discovery Cost Calculation Methodology
This calculator employs standard legal cost modeling to contrast traditional vendor-based review with AirgapAI-assisted workflows. It factors in document volume, review rates, and task-specific efficiencies while assuming on-device AI eliminates data transmission risks.
Core Formulas
Total Traditional Cost = (Pages × Traditional Min/Page / 60 × Reviewer Rate) + Privilege Cost + Key Doc Cost
Total AI Cost = AirgapAI Licenses + (Pages × AI Min/Page / 60 × Reviewer Rate) + Reduced Privilege/Key Doc Costs
Savings % = ((Traditional - AI) / Traditional) × 100
Team Size = Ceil(Review Hours / (Months × 160 Hours/Month FTE))
Component Breakdown
- Document Review: Total pages multiplied by review time per page (converted to hours) at vendor rates; AI reduces this by 40-60%
- Privilege Logging: Entries estimated per 1,000 pages, with 30 minutes per entry traditionally (attorney rate 2x reviewer); AI cuts to 12 minutes via automated tagging
- Key Document ID: 10% of review hours traditionally; AI reduces by 70% using Blockify for precise, explainable surfacing
- AirgapAI Costs: One-time perpetual licenses; no recurring fees, enabling broad team access
Key Assumptions
- Efficiency Gains: 40-60% time reduction from AirgapAI's local inference on legal datasets, backed by Blockify's 78X accuracy boost
- Team Capacity: 160 billable hours per month per reviewer; AI enables smaller teams or faster completion
- Privilege Protection: On-device processing inherently safeguards attorney-client privilege, avoiding vendor exposure
- Scope: Focuses on review costs; excludes hosting or production fees, which AI also streamlines via local Blockify ingestion
