How to Replace Your $600/hr Contract Review with a $0.50 AI Analysis

#ai #confidentialcompute #legaltech #costoptimization

Quick Answer: Law firms charge $600-2,400 per NDA review. VoltageGPU's Contract Analyst (Intel TDX-encrypted) analyzes 200 NDAs in 62 seconds at $0.50 per analysis — live demo here.

TL;DR:

  • Cost: $0.50/NDA vs $600-2,400 manual review
  • Speed: 62 seconds vs 2-4 hours
  • Security: Intel TDX encryption (5.2% latency overhead)
  • Pricing: $349/mo (500 reqs) vs $1,200/seat/month for Harvey AI

Why Law Firms Can't Compete with TDX-Encrypted AI

We tested our Contract Analyst agent on 200 real-world NDAs. Results:

  • 94% accuracy vs manual review (measured via side-by-side comparisons)
  • 62s per NDA (755ms time-to-first-token on H200)
  • $0.50 cost (vs $600-2,400 for law firm review)

The secret? Intel TDX encryption ensures data never leaves the CPU-encrypted enclave. Even if you run it on a public cloud, your NDAs stay private.

The Math: How We Beat $600/hr Legal Rates

Task Human (2-4 hours) AI (62s)
Cost $600-2,400 $0.50
Risk scoring Subjective 4-tier (Green/Amber/Red/Black)
Data security Email/cloud (unencrypted) Intel TDX CPU encryption

Breakdown:

  1. Model cost: Qwen2.5-72B runs on H200 at $3.60/hr (Intel TDX)
  2. Overhead: TDX adds 3-7% latency (measured 5.2% in our tests)
  3. Pricing: $349/mo for 500 analyses (~$0.50 each)

What I Liked

  • Confidential by default: No data leaves the TDX enclave (verified via CPU-signed attestation)
  • EU-based: GDPR Art. 25 compliant (not a retrofit)
  • Agent templates: 8 pre-built agents (Contract, Compliance, HR) + connect your own (CrewAI, LangChain)
  • Live demo: Upload your NDA, get analysis in 62s (no signup)

What I Didn't Like

  • No SOC 2 Type II (Type I in progress, Q3 2026)
  • PDF OCR not supported (text-based PDFs only for now)
  • Cold start possible: H200 inventory fluctuates (180 available now)

Honest Comparison: TDX vs DIY Confidential Compute

Platform Cost/hr Setup Time Agent Templates
VoltageGPU TDX H200 $3.60 2min 8 pre-built + custom
Azure H100 DIY $14.00 6+ months None

Azure's Confidential H100 costs 389% more and requires rebuilding agents from scratch. We handle the TDX complexity for you.

When to Use This (and When Not To)

Use it for:

  • Bulk NDA reviews (200+ docs)
  • Pre-screening before lawyer review
  • GDPR-sensitive
