Full Description
Your business deserves an AI assistant that works around the clock, answers intelligently, and fits seamlessly into your product. Whether you need a customer support bot, a sales assistant, a booking tool, or something entirely bespoke, Zinn Digital™ builds custom AI chatbots powered by GPT models, LangChain, and Hugging Face — delivered with clean source code and unlimited revisions.
Based in London, England, Zinn Digital™ specialises in the full development lifecycle of AI-powered chat solutions: from initial architecture through to a production-ready, integrated product. Every build is tailored to your specific workflow, brand tone, and technical environment.
**What we build:**
Customer support chatbots that handle FAQs and troubleshooting 24/7. Sales chatbots that drive conversions through personalised recommendations. E-commerce bots that simplify browsing, order tracking, and checkout. Booking and scheduling assistants that automate appointments and registrations. Educational bots for tutoring and customised learning journeys. Healthcare bots for symptom checking and patient enquiries. HR bots to streamline onboarding and internal communications. Voice-enabled chatbots for hands-free, accessible interaction.
**How it works:**
The Starter package delivers the essential foundation: sign-in, sign-up, user profile, and a full chat interface screen, all integrated with ChatGPT — complete with source code. The Standard package builds on this with a pre-set conversational journey, user authentication, and multi-language support, giving your chatbot a structured, professional personality from day one. The Full Build adds Retrieval-Augmented Generation (RAG) and CRM or database integration, turning your chatbot into a context-aware, data-connected powerhouse.
**Who this is for:**
Startups wanting a polished AI product quickly. Businesses looking to automate repetitive customer interactions. Developers who need a well-structured, extensible codebase to continue building on. Product teams integrating AI into an existing web or mobile app.
**Why Zinn Digital™:**
We work across the leading AI and LLM frameworks — GPT models, LangChain, Hugging Face, ManyChat, and LLM architectures — and we integrate seamlessly with existing systems without disrupting what already works. Every project is backed by unlimited revisions and a commitment to your outcome, not just delivery.

Frequently Asked Questions
To kick things off, it helps to share a brief description of your project goals, your preferred tech stack or platform (if you have one), and any branding or tone-of-voice guidelines. The more context you provide, the faster we can begin. If we need anything further, we'll reach out via the order chat.
Yes. We specialise in seamless AI integration, ensuring new functionality enhances your existing product without disrupting current features or user experience. Please share relevant technical details when placing your order.
RAG allows your chatbot to retrieve information from your own documents, knowledge bases, or databases before generating a response — making answers far more accurate and specific to your business. It is included in the Full Build package and is particularly valuable for support bots, internal tools, and knowledge-heavy use cases.
It means we will continue iterating on the deliverable until you are satisfied, within the agreed scope of the package. Revisions cover refinements to the functionality, design, and behaviour described in your brief — not additions that constitute a new project.
Delivery times are 7 days for Starter, 14 days for Standard, and 21 days for Full Build. If you need it sooner, the Extra Fast Delivery add-on can significantly reduce your turnaround time. Complex bespoke requirements may affect timelines, which we will discuss upfront.
Yes. Ongoing support and maintenance is available as an add-on, covering post-launch assistance to keep your AI system running smoothly and up to date. You can also discuss longer-term arrangements via the order chat.
Yes. Every package includes full source code delivery, so you retain complete ownership and can continue developing the product independently or with your own team.
Absolutely. We have built chatbots for customer support, sales, e-commerce, booking and scheduling, education, healthcare, HR, and voice-enabled applications. If your use case is not listed, get in touch via the order chat and we can discuss a tailored approach.
