HST Solutions builds AI assistants and enterprise chatbots powered by leading large language models for organisations across Ireland, the UK, and Europe, connected to proprietary data through RAG pipelines and vector databases. ISO 27001 certified since 2007.
Beyond Basic Chatbots
If you’ve tried a chatbot builder before Intercom, Drift, Tidio you know the limitations. They follow scripts. They break when customers ask anything unexpected. They feel robotic.
LLM-powered assistants are fundamentally different. They understand natural language, handle complex multi-turn conversations, and can be connected to your business data so they give accurate, specific answers rather than generic responses.
But implementing them properly requires more than calling the ChatGPT API. You need prompt engineering, data pipeline architecture, security controls, cost management, testing frameworks, and integration with your existing systems. That’s what we do.

Frequently asked questions
How much does a custom AI chatbot cost to build?
A basic AI assistant connected to your knowledge base typically costs €20,000–€40,000 for development and deployment. More complex implementations with multiple system integrations, multi-channel deployment, and advanced workflows range from €50,000–€120,000. Ongoing model API costs (GPT-4, Claude, etc.) typically run €200–€2,000/month depending on usage volume.
Can the AI assistant access our internal systems?
Yes. We integrate AI assistants with CRM systems, databases, ERPs, ticketing systems, SharePoint, and custom internal tools via APIs. The assistant can both read data (to answer questions) and write data (to create tickets, update records, process orders) based on your requirements.
How do you ensure the AI doesn't give wrong answers?
We implement RAG to ground responses in your actual data, require source citations in answers, use confidence scoring to flag uncertain responses, and set up human-in-the-loop workflows for high-stakes queries. We also build comprehensive test suites to validate accuracy before deployment.
Can we start with a small pilot?
Absolutely. Our recommended approach is to start with a focused proof of concept — usually a single use case with a defined knowledge base — validate that it works, then expand. A PoC typically takes 4–6 weeks and costs €15,000–€25,000.
What happens when the AI can't answer a question?
We design graceful fallback workflows: the assistant acknowledges it doesn’t know, offers related information if possible, and escalates to a human agent with full conversation context so the customer doesn’t have to repeat themselves.
