What You'll Receive
Full Description
Your customers expect instant answers — at 2 pm and at 2 am. A professionally built AI chatbot delivers exactly that: immediate, accurate, on-brand responses around the clock, without adding headcount or overhead.
We are a London-based software engineering team with 10+ years of experience in AI and automation. As Certified Voiceflow Experts, we design, build and integrate bespoke AI chatbots tailored precisely to your business goals — whether that is resolving customer service queries, capturing leads, handling general enquiries, or all three at once.
**What sets our chatbots apart:**
Every bot we build is custom — not a template dropped into your site. We begin with your business objectives, map the conversation flows your customers actually need, and engineer prompts that produce responses that feel genuinely helpful and on-brand. We connect your bot to thousands of platforms and APIs via Make.com and Zapier, meaning it can talk to your CRM, your helpdesk, your calendar or your e-commerce stack without friction.
We harness leading generative AI models through Voiceflow's infrastructure, complemented by OpenAI Assistants for natural, human-like conversation, and ManyChat where social-media integrations are needed. The result is a chatbot that handles complex, nuanced queries — and knows when to escalate gracefully to a human agent.
**What is included across all packages:**
- Custom AI chatbot built in Voiceflow, aligned to your specific use case
- Prompt engineering optimised for personalised, accurate responses
- Knowledge base integration so the bot answers from your own content
- Mobile-friendly design that works seamlessly across desktop, tablet and smartphone
- GDPR-conscious build with robust security measures
- Smooth handoff to a human agent (live chat or email) for out-of-scope queries
- Post-delivery support for technical questions
**Who this is for:**
This service is ideal for SMEs, e-commerce brands, SaaS companies, professional services firms and any business that wants to reduce support workload, improve response times and convert more website visitors — without compromising on quality.
**How it works:**
1. You place your order and share your requirements via the order chat
2. We review your brief and may ask clarifying questions
3. We design and build your custom chatbot
4. We deliver, you review, and we refine within the agreed revision rounds
5. We integrate the finished bot onto your chosen platform
Quality and transparency are at the heart of everything we do. We keep you informed at every stage and will not sign off until the chatbot meets your expectations.
Zinner Quality Guarantee

All services are backed by our quality assurance commitment.

Frequently Asked Questions
We ask you to share your business context, the primary purpose of the chatbot (e.g. customer service, lead capture, FAQs), any existing knowledge base or FAQ documents, and details of the platforms or systems you would like the bot to connect with. The more detail you provide, the faster we can get building.
Delivery times are 7 days (Basic), 21 days (Boost) and 30 days (Premium). These reflect the genuine complexity involved in building, testing and integrating a custom chatbot. If you need delivery sooner, the Extra Fast Delivery add-on reduces your timeline significantly.
Yes — Boost and Premium packages include Make.com and Zapier integrations, which connect your chatbot to thousands of platforms including popular CRMs, helpdesks, calendars and e-commerce tools. Please mention the specific systems you use in your brief so we can plan the integration accordingly.
We build in a graceful escalation flow: the chatbot recognises when a query is beyond its scope and routes the customer to a human agent via live chat or email. Please include your preferred escalation method in your project brief.
Security and compliance are a priority. Every chatbot is built with robust security measures and can be designed to align with GDPR requirements — including appropriate data handling, consent prompts and user data minimisation. If you have specific compliance requirements, please outline them in your brief.
Yes. Fixed responses and knowledge base content can be updated after delivery. We also offer ongoing maintenance and updates as an optional add-on, which is ideal if your products, services or policies change regularly.
Multilingual chatbot capability is included in the Premium package. If you serve a global audience and need your bot to converse in multiple languages, Premium is the right choice — please specify the required languages in your brief.
The chatbot can be deployed on your website (across desktop, tablet and smartphone), and — depending on the package — on social media channels and messaging platforms via ManyChat integration. Let us know your target deployment channels when you place your order.

He's the guy
Juan Neilos is an incredible professional software engineer! He not only exceeded our expectations with his exceptional documentation and professionalism but also demonstrated deep understanding and language fluency. Juan swiftly solved what other freelancers couldn't, delivering a highly performant AI chat-bot. I look forward to future projects with him!
Juan is amazing. He's a great software engineer. He really knows a lot; we've been facing challenging situations on our project, but he always has a solution or an initiative to rethink and achieve our goals. I fully recommend working with him.
I doubt you will find anyone better than King Juan Neilos to develop a chatbot on Zinn Hub. The combination of his way of thinking (simplifying, structure, accuracy) with professionalism made my project a huge success. I am so grateful that I met him.
