Nerdster Vault
Custom AI built around your workflows, deployed where your data already lives. Run it on a dedicated cloud silo we set up and manage for you, or fully on-site air-gapped on hardware you own. Either way, your data never trains a public model and never leaves your perimeter.
Your data. Your model. Your cloud or your building.
Trained on Your Data
Your documents, contracts, policies and case files are ingested and used to fine-tune the model inside your perimeter, never externally. The AI learns your terminology, your precedents, your processes.
Cloud Silo or On-Site
Two deployment modes. We can run Vault in a dedicated cloud silo (AWS London, Azure UK South or your own tenant) and manage it for you, or install it fully on-site air-gapped on hardware you own. Same model, same controls, you choose where it lives.
Purpose-Built Agents
Custom workflow agents built on your trained model. Understands your document types, approval flows and compliance obligations, not generic chatbot behaviour.
Zero Data Leakage
No public LLM calls. No telemetry. No licence-validation phone home. Your prompts, documents and outputs stay inside your tenancy whether that is a cloud silo or on-site.
Cloud Silo or On-Site
