What You'll Receive
Full Description
Imagine your business answering customer questions instantly, 24/7, in any language — without hiring extra staff. That is exactly what a custom AI chatbot built on GPT-4 and n8n workflows delivers. This is not a generic template; every chatbot is engineered from the ground up for your specific use case, industry, and brand.
Zinn Digital is a London-based agency with 7+ years specialising in AI chatbot development and automation. We build production-ready solutions that you own completely — full source code, all n8n workflows, and every configuration file. No monthly platform fees, no lock-in, no black boxes.
**What we deliver:**
Every package begins with a free discovery call to map your automation goals before a single line of code is written. We design conversation flows drawn from your FAQs, knowledge base, and brand voice. We connect your chatbot to the channels your customers already use — WhatsApp Business API, website widgets, Shopify, WordPress, or Telegram. You receive complete n8n workflows, source code, a walkthrough tutorial, and one week of post-launch support so you are never left on your own.
Higher tiers extend this foundation significantly. The Standard build adds Retrieval-Augmented Generation (RAG), which grounds every AI response in your actual documents, manuals, and website content so the chatbot answers with real accuracy rather than guesswork. It also includes user authentication and a pre-set conversational journey that guides visitors through a structured, goal-driven interaction. The Full build extends the scope further, adding direct CRM and database integration so the chatbot reads from and writes to your live business data — closing the loop between customer conversation and back-office operations.
**How the process works:**
We start with a discovery call, deliver a working prototype, iterate until you are satisfied, then launch. Average response time during the project is under one hour.
**Who this is for:**
E-commerce stores wanting to automate order queries and support. Service businesses needing 24/7 appointment booking and FAQ handling. SaaS companies looking to onboard users or handle tier-one support. Any organisation that wants to replace repetitive, manual customer conversations with intelligent, always-on automation.
**Why Zinn Digital:**
Seven-plus years in AI and automation. Based in London, England. Transparent pricing with no hidden costs. You own everything we build. Fast, clear communication throughout. Message us with your use case and let us show you what your chatbot can do.

Frequently Asked Questions
We specialise in WhatsApp Business API, website widgets, Shopify, WordPress, and Telegram. We can also integrate with most CRM systems, booking platforms, and payment processors such as Stripe through custom n8n workflows.
Yes, absolutely. You receive complete ownership of all n8n workflows, source code, and chatbot configurations. There is no vendor lock-in and no ongoing platform fees payable to us.
Yes. The Standard and Full Build packages include Retrieval-Augmented Generation (RAG), which trains the AI on your documents, FAQs, product manuals, and website content so responses are grounded in your actual information rather than generic knowledge.
We start with a free discovery call to understand your goals. Before or after that call it helps to share any existing FAQs, knowledge base documents, brand guidelines, and details of any tools or platforms you need connected. The more context you provide, the more accurately we can tailor the chatbot from day one.
All three packages include three revisions. A revision covers amendments to conversation flows, tone, response logic, or integration behaviour based on your feedback after the prototype is delivered. Entirely new features or additional integrations outside the agreed scope would be quoted separately.
After you place your order, we will reach out to schedule a discovery call. We then build and deliver a working prototype, iterate based on your feedback within the revision allowance, and launch when you are satisfied. We provide a tutorial walkthrough and one week of post-launch support.
We build custom n8n workflows tailored to your specific business processes, industry, and brand voice — not generic templates configured in a drag-and-drop editor. You own the underlying code and can extend or self-host the solution independently after delivery.
