What You'll Receive
Full Description
Your customers expect instant, intelligent responses at any hour. A custom AI chatbot powered by ChatGPT or a fine-tuned LLM delivers exactly that — reducing support load, increasing conversions, and keeping users engaged without adding headcount.
Zinn Digital is a London-based AI development studio specialising in building, fine-tuning, and integrating powerful AI chatbots and custom GPT models. Whether you need a simple chat interface or a fully connected, RAG-powered assistant that pulls from your own data and syncs with your CRM, we build it to your exact specification and hand over clean, documented source code.
**What kind of chatbot can we build for you?**
We cover the full range of use cases — customer support bots that handle FAQs and troubleshoot issues 24/7, sales bots that guide users toward purchase decisions, e-commerce bots that help customers browse, track orders, and check out, booking and scheduling bots that automate appointments and registrations, educational bots for tutoring and personalised learning, healthcare bots for symptom triage and scheduling, HR bots for onboarding and internal queries, and voice-based bots for hands-free interaction.
Not sure which type fits your needs? Every package can begin with a free consultation so we can scope the right solution together.
**What is included across all tiers?**
Every build includes a fully functional chat interface, ChatGPT / LLM model integration, and complete source code delivered to you. Larger tiers add pre-set conversational journeys, user authentication, multi-language support, Retrieval-Augmented Generation (RAG) for knowledge-base connectivity, and full CRM or database integration — the full scope is detailed in the package table below.
**How it works**
1. You place your order and share your project details via the order chat.
2. We review your requirements and confirm scope (we will reach out with any questions).
3. Development begins — we keep you updated throughout.
4. Delivery of your chatbot with source code, ready for deployment.
5. Unlimited revisions until you are satisfied.
**Who is this for?**
Startups and established businesses alike — e-commerce stores, SaaS platforms, healthcare providers, educational institutions, HR teams, and any organisation that wants to automate conversations intelligently. No technical expertise is needed on your side; we handle the complexity and guide you through deployment.
**Why Zinn Digital?**
We are specialists in ChatGPT, GPT models, and large language models — not generalist developers who dabble in AI. Our solutions are tailored, scalable, and built with security and privacy compliance in mind. Sensitive data handling, encryption, and privacy features can be incorporated as your use case requires. You receive source code ownership, unlimited revisions, and a team that is genuinely invested in getting the result right.

Frequently Asked Questions
Simply share a description of your project, your website or app platform, your primary use case (e.g. customer support, sales, bookings), and any specific features you have in mind. The more detail you provide, the faster we can begin. If anything is unclear, we will follow up via the order chat.
No technical background is required. We design chatbots to be user-friendly and provide guidance to ensure you are comfortable using and maintaining your chatbot. Full source code is also handed over so your own developers can build on it if needed.
RAG allows your chatbot to retrieve and reference information from your own documents, knowledge base, or database in real time — rather than relying solely on the base LLM. It is ideal if you want the bot to answer questions accurately using your specific product information, policies, or internal data. This feature is included in the Premium tier.
All three tiers include unlimited revisions. We work with you until you are fully satisfied with the result.
We can integrate the chatbot into most websites and web applications. If you are using a specific platform, CMS, or custom stack, please mention it in your requirements so we can confirm compatibility before work begins.
Yes. Chatbots can be designed with security protocols — including encryption and privacy features — to handle sensitive information in compliance with data privacy regulations. Please flag your compliance requirements at the start of the project.
Standard rule-based chatbots follow fixed scripts and struggle with unexpected queries. Custom GPT and LLM-based chatbots understand natural language, generate context-aware responses, and adapt to a much wider range of user inputs — delivering a far more intelligent and flexible experience.
Yes. If your needs grow during the project, please message us via the order chat and we can discuss upgrading your scope. Additional features will be scoped and priced transparently before any work begins on them.
