Harvey AI vs VoltageGPU: $1,200/seat vs $349/mo — We Compared Accuracy and Security
Quick Answer: Harvey AI charges $1,200/seat/month for contract analysis on shared infrastructure. VoltageGPU’s Confidential Agent Platform runs inside Intel TDX enclaves on H200 GPUs for $349/mo — 8 pre-built templates + connect your own agents (CrewAI, LangChain). Even we can’t read your documents.
Look, TL;DR: I tested VoltageGPU’s Contract Analyst on 200 NDAs. Average analysis time: 62 seconds. Risk scoring accuracy: 94% vs manual review. Intel TDX overhead: 5.2% vs non-encrypted inference. Cost per analysis: ~$0.50. Harvey AI’s per-seat model is 20x more expensive with no hardware encryption.
Why Hardware Encryption Matters
Harvey AI processes documents in the cloud on shared infrastructure. The data is unencrypted in GPU memory during inference. Any hypervisor-level compromise could expose it.
VoltageGPU uses Intel TDX (Trusted Domain Extensions) to create hardware-isolated execution environments. The CPU encrypts data in RAM — no software, including ours, can access it. This is GDPR Art. 25 native, not a retrofit.

Results: Contract Analyst vs Manual Review
| Metric | Harvey AI | VoltageGPU Contract Analyst |
|---|---|---|
| Time per NDA | 2-4 hours | 62 seconds |
| Cost | $1,200/seat/month | ~$0.50/analysis |
| Confidential | No hardware encryption | Intel TDX (hardware) |
| Risk scoring | Subjective | 4-tier (Green/Amber/Red/Black) |
| Cold start time | N/A | 30-60s on Starter plan |
| PDF OCR support | No | No (text-based only) |
What I Liked
- VoltageGPU Confidential Agent Platform: 8 pre-built templates (contract, financial, medical, HR) + connect your own agent via API.
- EU company (France): GDPR Art. 25 native, not a retrofit.
- Hardware attestation: CPU-signed proof your data ran in a real enclave.
- Live demo: Upload your own document, real analysis, no signup.
The reality is ---
What I Didn’t Like
Worth noting: - No SOC 2 certification (relies on GDPR Art. 25 + Intel TDX attestation).
- TDX adds 3-7% latency overhead vs non-encrypted inference.
- PDF OCR not supported (text-based only for now).

Honest Comparison with Azure Confidential
Azure Confidential H100: $14/hr — DIY, no agents, 6+ months setup.
VoltageGPU TDX H200: $3.60/hr — platform with templates + bring your own agent, ready in minutes.
74% cheaper, but Azure has more certifications (for now).
Cost Comparison Table
| Feature | Harvey AI | VoltageGPU |
|---|---|---|
| Pricing model | $1,200/seat/month | $349/mo (Starter), $1,199/mo (Pro) |
| Seats included | 1 per license | 3 seats (Starter), 10 seats (Pro) |
| Confidential computing | No | Intel TDX (hardware) |
| Cold start time | N/A | 30-60s (Starter) |
| PDF OCR | No | No |
| OpenAI-compatible API | No | Yes |
| Model size | N/A | Qwen3-32B (Starter), Qwen3-235B (Pro) |
| DPA available | No | Yes (GDPR Art. 25) |
Accuracy and Performance
I tested the VoltageGPU Contract Analyst on 200 real NDAs. Manual review by a law firm associate found 47 critical risks. The AI found 44 — a 94% match rate. False positives? 3. False negatives? 3.
Harvey AI’s manual review process is slower and more expensive. One lawyer told me, “I spent 3 hours setting up Azure Confidential. Gave up after 2 days of no results.”
VoltageGPU’s TDX overhead is 3-7% — not perfect, but acceptable for 94% accuracy at 62 seconds per NDA.
Security and Compliance
VoltageGPU is a EU company (France, SIREN 943 808 824). We don’t have SOC 2, but we offer:
- Intel TDX attestation on every GPU session
- Zero data retention — data is deleted after inference
- GDPR Art. 25 compliance (by design, not retrofit)
- DPA available on request
- No training data sharing — your data never leaves the enclave
Harvey AI runs on shared infrastructure. No hardware encryption is mentioned in their documentation. Their pricing suggests a seat-based model — not per-use, which is odd for an AI service.

Use Cases and Recommendations
-
Use VoltageGPU if you need:
- Confidential AI for legal, finance, HR, or medical analysis
- GDPR compliance without retrofitting
- A platform with pre-built agents or your own (CrewAI, LangChain)
- Cost control (pay for what you use, not per seat)
I've been digging into this and - Use Harvey AI if you need:
- A seat-based model (for teams)
- No GPU management (though their pricing model is confusing)
- Less concern for data isolation and encryption
Final Thoughts
VoltageGPU is 20x cheaper than Harvey AI and offers hardware encryption out of the box. The accuracy is close enough for most legal and compliance tasks. The only catch? PDF OCR isn’t supported yet and TDX adds a small latency hit.
This matters because but here’s the kicker: VoltageGPU is EU-based, GDPR Art. 25 native, and gives you full attestation of your data’s security. Harvey AI doesn’t mention any of that.
