A UK AI consultancy that builds production systems, not pilots
Node Digital is a UK-based AI consultancy. We design, build and operate AI systems for businesses, from private GPT deployments and RAG chatbots to machine learning and predictive analytics, hosted on UK infrastructure you control.
Our AI stack is built on LangChain for orchestration, CrewAI for multi-agent collaboration and Temporal for durable workflow execution, running on private UK GPU infrastructure with access to frontier models from Anthropic, Google and OpenAI. Your confidential data stays on private infrastructure, which keeps UK GDPR compliance straightforward and your information out of anyone else's training data.
Private GPT deployment: a privately hosted AI assistant for your team, with the convenience of ChatGPT and none of the data residency concerns. See PrivateGPT.
RAG chatbots and knowledge assistants: chatbots grounded in your own documents and data, with answers cited back to source. See RAG chatbot development.
Predictive analytics: by analysing your operational and customer data, we build models for demand forecasting, churn prediction and anomaly detection that feed decisions, not slide decks.
Customer service automation: AI assistants that handle routine queries around the clock and hand off to humans with full context, reducing response times without degrading service.
Personalisation: recommendation and targeting systems built on your first-party data, tailoring products, content and offers to individual customer behaviour.
Risk and compliance: real-time analysis to identify anomalies, prevent fraud and evidence regulatory compliance, integrated with your existing systems.

Frequently asked questions
What is PrivateGPT and why would I use it instead of ChatGPT?
PrivateGPT gives you the same conversational AI experience but your data never leaves your walls. It runs on private GPU infrastructure in the UK, giving you full control over data residency, auditability and compliance. Ideal for regulated industries.
What is a RAG chatbot?
A Retrieval-Augmented Generation chatbot combines a large language model with your own documents and knowledge base. It searches your data first, then generates accurate answers grounded in your specific content rather than general training data.
Do you build AI solutions using LangChain?
Yes. Our AI stack is built on LangChain for orchestration, CrewAI for multi-agent collaboration and Temporal for durable workflow execution. This combination allows us to build production-grade AI systems that are reliable and maintainable.
Can AI run on our own infrastructure?
Yes. We operate a hybrid AI platform combining private UK-hosted GPU infrastructure with access to frontier models from Anthropic, Google and OpenAI. Your confidential data stays on private infrastructure while benefiting from the latest model capabilities.
What industries do you serve with AI solutions?
We work across sectors including financial services, healthcare, retail, media and manufacturing. Our AI solutions are designed to integrate with existing business processes rather than requiring wholesale change.
