Scale your productivity with private AI

Take control of cost, data privacy and institutional knowledge with your own private LLM platform.

Your intelligence. Your infrastructure.

CTI Digital provides a completely isolated, secure environment where cutting-edge large language models (LLMs) meet your proprietary knowledge. This isn't just a chatbot; it’s a secure digital extension of your team that understands your brand, respects your boundaries, and operates entirely within your control.

What is a private LLM platform?

We believe the market is moving from renting AI to owning AI

Businesses that rely on third-party SaaS AI tools face growing risks around data privacy, cost, and control.

That’s why at CTI Digital, we believe the market is moving from renting AI to owning AI.

Currently, many teams are accessing popular cloud AI services and chatbots such as Claude and ChatGPT, which may mean using proprietary models that are subject to change, worrying about confidential data leakage where staff are using public interfaces, or racking up unforeseen costs as usage grows.

Local LLMs offer a different path. Instead of sending your prompts and data to a third-party cloud, a local model runs in an environment you control: either on hardware in your office or on your own dedicated hosting. The intelligence stays in-house. And for organisations handling sensitive data, operating in regulated industries, or simply wanting greater control over how AI is used, that distinction matters enormously.

Our private AI platform includes a chatbot-style user interface, powerful open-source LLMs, managed hosting or on-prem infrastructure, and customisation with your own proprietary knowledge. Then add our pre-configured bolt-ons to power your productivity, from agents and workflows to your own brand library.

Modular skills for ‘out of the box’ functionality

Skills are modular, configurable and scalable. You choose the skills you need, and add more as you grow. Common use cases include:
  • LLM chat

    Conversational AI powered by self-hosted large language models. Supports multi-turn conversations, system prompts, persona configuration, and role-based access.

     

  • Brand library

    Feed your private instance with specific brand guidelines, past work, and proprietary knowledge. Your AI learns to think in line with your teams. Use your private model to ensure every output adheres strictly to your specific style guides and brand pillars.

  • Image generation

    On-premise AI image generation. Generate marketing assets, product visuals, and creative content without sending data to external image APIs. Fully private and brand-safe.

  • Knowledge banks powered by RAG

    Think of RAG (Retrieval-Augmented Generation) as handing the AI your company filing cabinet, so it answers from your data and facts, not just general knowledge. From tender or HR bots, to querying your own historical campaign data and internal documents in order to uncover trends and insights instantly, all without risking a single byte of data leakage.

  • Workflows

    Visual workflow orchestration for complex, multi-step business processes. Trigger AI actions based on events, schedules, or user inputs. Integrate with CRM, ERP, helpdesk, and other business systems via API.

  • Agents

    Intelligent AI agents that can take actions, not just answer questions. Agents can query databases, send emails, create tickets, and execute multi-step tasks autonomously. Configurable with guardrails and human-in-the-loop approval flows.

A tried and tested alternative to ChatGPT

Our private AI stack and CTI LLM began life as an internal tool. That makes us 'our own first client'. Now we're helping our clients deliver the same value from generative AI - taking them from concept to deployment in three simple steps.

The CTI Digital private AI stack

Our private AI platform is a fully integrated, four-layer stack. Each layer is scalable and secure with a clear owner.

  • The CTI LLM has an extensible, feature-rich, and user-friendly self-hosted AI interface. So your team will already know how to use it.

    1.
    The interface
  • Self-hosted large language models, ready for RAG, agents and workflow orchestration.

    2.
    The intelligence
  • A solution to suit you, supported by our sister hosting company Nublue.

    3.
    The infrastructure
  • Owned and accessed only by you.

    4.
    The data

Layer 1: The interface

A modern, ready-to-use AI interface with:

  • multi-user support;
  • role-based access control;
  • conversation history;
  • and a branded user-facing portal.

Accessible via browser or web app. Deployed, configured and maintained for you, with document Q&A and knowledge retrieval.

Our local LLM was built and hosted by our team in-house, and is used extensively across our agency.

Layer 2: The intelligence

Open-source, self-hosted LLMs. Easy to switch, scale and run on GPU hardware, using model serving frameworks such as vLLM.

All run privately with no external API calls, no usage fees, and no data leaving the environment.

With RAG for document search and context-aware responses, AI agents for task automation, and easy-to-use workflow orchestration.

Layer 3: The infrastructure (Nublue operated):

Run by Nublue – managed hosting experts and part of the CTI Digital Group.

We offer both an on-premises approach (your Local LLM is hosted on hardware we install, that lives within your organisation), and a private cloud AI option (where we host for you on a secure AWS environment). In both cases, your data never leaves an environment you control.

Layer 4: The data (owned by you)

Your own documents, databases, and proprietary knowledge. Ingested, indexed, and stored securely within your private environment.

Learn how private AI could drive value and reduce costs for your business

Local LLMs your organisation can trust

Private AI can be tailored to your unique marketing workflows. With no data leaks, no public training, and no compromising on privacy. Just the scalable AI-powered features that will grow with your business.
  • Total data sovereignty

    You maintain absolute ownership of your data and the infrastructure it lives on. Zero exposure of your assets to third-party SaaS AI tools. 

  • No leaks

    Your sensitive campaign strategies, upcoming product launches, and client briefs won’t become part of a public model’s training set.

  • Designed for regulated industries

    Productivity for regulated industries such as healthcare, government, education or professional services. Or for any data-conscious organisation that needs to avoid the grey area of third-party public models.

  • Brand guardianship and consistency

    Standard AI outputs often lack the nuance, tone, and "DNA" that make your brand unique. Train your AI on your organisation to ensure every output measures up.

  • Predictable scalability

    Move away from unpredictable API costs. Our solutions are designed to offer capability without the pricing spikes.

  • Future-proof compliance

    Stay ahead of global data regulations by keeping your intellectual property behind your own digital walls.
