OpenAI

What OpenAI is

OpenAI is an artificial-intelligence research company best known for the GPT family of large language models (LLMs) and the API that makes them available to build with. A large language model is software trained on vast amounts of text to understand and generate natural language: give it a question or instruction in plain English and it can answer, summarise, classify, translate or write a reply.

For a business, the practical value isn’t the technology itself, it’s that a GPT model can hold a natural conversation, understand what a website visitor is actually asking even when they phrase it loosely, and respond helpfully. That’s what makes it the engine behind useful chatbots and automations rather than a clunky, keyword-matching FAQ widget.

How HDC uses OpenAI

We use OpenAI’s models to build two kinds of thing for clients: website assistants and behind-the-scenes automations.

• We embed a chatbot, powered by a GPT model, into the sites we build. We brief it on the client’s services, service areas and how they work, so it answers visitor questions accurately and in the business’s tone.
• We design it to qualify, to ask the few questions that decide whether an enquiry is worth pursuing (job type, location, urgency) and capture the visitor’s contact details.
• We use function-calling so the model can trigger real actions: route a summary to the inbox, log it in the CRM, fire a notification.
• We wire those outputs through Zapier or Make so a qualified lead flows straight into the tools the team already uses, around the clock.

Why we apply it

Most local businesses lose enquiries to timing. Someone visits the site at 9pm, has a question, gets no answer, and books the next firm by morning. An always-on assistant closes that gap: it answers the question, screens the lead and hands the team a warm, pre-qualified summary to follow up, instead of a missed call and a cold trail.

It also saves the team’s time on repetitive first-contact questions, so they spend it on the work that pays. The point isn’t novelty; it’s catching and warming more of the enquiries the marketing already worked to win.

How OpenAI fits our stack

OpenAI’s models are one of two AI engines we build on, the other is Claude, which we choose when reasoning depth or stricter safety leads. Whichever model powers the assistant, it lives on a site built with Astro and connects outward through Zapier and Make to the client’s CRM, inbox and Brevo email follow-up. So an AI-qualified lead doesn’t just sit in a chat window, it flows into the same automated pipeline as every other enquiry, ready for the team to act on.

When OpenAI isn’t the right tool

AI isn’t always the answer. When responses must be 100% deterministic or legally exact, fixed quotes, compliance wording, contractual terms, we don’t let a model improvise; we collect details and route them to a human. Where the work hinges on careful reasoning over nuanced material or stricter safety guarantees, we’ll often reach for Claude instead. And for a simple business with a handful of fixed questions, a plain FAQ page or a basic form may serve better than any AI at all, we recommend the simplest thing that does the job well.
