ChatGPT Enterprise removes model training on your prompts, but every document you upload and every prompt you send still traverses OpenAI's cloud. For NDA-bound, HIPAA, or attorney work-product material, that vendor cloud hop is the blocker. PrivateDocs AI runs the same kind of 'chat with your documents' workflow entirely on your hardware.

PrivateDocs AI vs. ChatGPT Enterprise, ChatGPT Team, and Microsoft Copilot for confidential document workflows
| Feature | PrivateDocs AI | ChatGPT Enterprise |
|---|---|---|
| Where prompts and documents are processed | On-device document and AI processing | Sent to OpenAI / Microsoft cloud infrastructure |
| DPA & subprocessor review | Not required for AI workloads | Mandatory OpenAI / Microsoft DPA + tenant setup |
| Training on your data | Impossible — we never see your data | Disabled by policy, but still processed in cloud ChatGPT Enterprise opts you out of training, but content still passes through OpenAI servers for inference. |
| Air-gapped operation | Full local inference after activation | Requires active internet connection |
| Vector store & document retention | Local ChromaDB vault on your disk | Hosted in your OpenAI workspace |
| Citations to source documents | Citations can link to retrieved source passages | Requires custom GPT / Copilot setup |
| Pricing | $249 one-time lifetime license | $60+/user/month, billed annually |
For 'chat with your own documents' workflows, yes. PrivateDocs AI uses modern open-source LLMs (Llama 3, DeepSeek, Mistral) through a bundled Ollama runtime, indexes your files in a local ChromaDB vault, and generates per-message citations. The quality is comparable on document Q&A and summarization — and the privacy posture is fundamentally stronger because no document or prompt ever leaves your machine.
ChatGPT Team still routes prompts and uploaded files through OpenAI's cloud. If your client contract, NDA, or regulatory posture prohibits that egress, Team doesn't help. PrivateDocs AI gives you the same conversational document workflow with zero egress.
Copilot grounds responses in your Microsoft 365 tenant — but the inference still happens in Microsoft's cloud. If you need true on-device processing for confidential matters, use PrivateDocs AI for those documents and reserve Copilot for non-sensitive work.
$249 one-time license. No recurring fees. Document content stays local for AI processing.
