ChatGPT, Claude, Gemini, and Copilot are incredible tools — but every prompt and uploaded document traverses a third-party cloud. For legal, financial, healthcare, and client-NDA-bound teams, that egress is a non-starter. PrivateDocs AI keeps the entire workflow on your hardware.

PrivateDocs AI vs. ChatGPT, Claude, Gemini, and Copilot for confidential documents
| Feature | PrivateDocs AI | Cloud AI Chatbots |
|---|---|---|
| Where prompts and documents live | On-device document and AI processing | Sent to third-party cloud servers Cloud chatbots may retain prompts for model training or safety review depending on plan and tenant settings. |
| DPA & subprocessor review | No DPA for the on-device AI path; review control-plane data separately | Mandatory enterprise DPA + subprocessor audit |
| NDA / client-confidentiality compliance | Can reduce third-party AI data sharing; compliance remains your responsibility | Risk of data leakage and retraining |
| HIPAA / GDPR / SOC 2 posture | Documents never leave the corporate perimeter | Depends on vendor plan and toggles |
| Offline / air-gapped use | Full local inference after activation | Requires active internet connection |
| Token limits and rate caps | No token meter; subject to model, file, and hardware limits | Per-plan token caps and queue waits |
| Cost over 12 months (5 users) | $895 lifetime (5 seats, one-time) | $1,800–$3,600+/year (recurring, per-seat) |
| Hardware optimization | Apple Silicon and suitable dedicated graphics hardware | Shared cloud capacity |
PrivateDocs AI is built for exactly that use case. It runs an open-source LLM locally through Ollama, indexes your case files and contracts in a local ChromaDB vault, and generates per-message citations back to source paragraphs — all without any document or prompt leaving your machine. That makes it safe for client-NDA-bound and attorney work-product material.
Modern open-source models (Llama 3, DeepSeek, Mistral, Qwen) approach frontier-cloud quality on document Q&A and summarization while running comfortably on Apple Silicon or a mid-tier GPU. For high-stakes legal, financial, or regulatory work, the privacy and citation guarantees often outweigh marginal quality differences.
Copilot integrates tightly with your tenant but still sends prompts and grounding content through Microsoft's cloud. If your matter or client engagement prohibits third-party cloud processing, Copilot is off the table. PrivateDocs AI gives you similar 'chat with your documents' workflows entirely on your hardware.
Many teams do exactly that. Cloud chatbots are great for general research; PrivateDocs AI is the right tool the moment a document is covered by an NDA, attorney work-product privilege, HIPAA, GDPR, or any clause that prohibits third-party processing.
$249 one-time license. No recurring fees. Document content stays local for AI processing.
