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:
- Model cost: Qwen2.5-72B runs on H200 at $3.60/hr (Intel TDX)
- Overhead: TDX adds 3-7% latency (measured 5.2% in our tests)
- 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
