# I Will Build and Deploy a Custom AI Chatbot or Voice AI Agent

Your customers expect instant, accurate answers around the clock. Whether that means a chat widget on your website, a WhatsApp bot that qualifies leads overnight, or a voice agent that handles inbound calls and processes payments — this service delivers a fully built, tested, and deployed AI solution matched precisely to your business requirements.

Zinn Digital® is a London-based AI and web development studio with over ten years of experience across machine learning, conversational AI, and production software. We have delivered more than 100 live bots across SaaS, e-commerce, and fintech — not prototypes, but systems handling real customers at scale.

\*\*What You Receive\*\*

Every engagement is scoped during a dedicated discovery call so the solution fits your stack and your goals. Depending on the tier you choose, delivery spans from a focused consultation and proof-of-concept all the way through to a fully integrated, fine-tuned multi-channel AI system.

Core capabilities we bring to each build include:

— Website, WhatsApp, Slack, and Messenger chatbots powered by GPT
 — Natural-language voice IVR and phone agents via Twilio, VAPI, Retell AI, Synthflow, or SIP
 — Secure fine-tuning and Retrieval-Augmented Generation (RAG) so every reply reflects your brand, products, and policies
 — Conversational flow design, prompt engineering, and UX copy
 — Dashboards, analytics, and human hand-off routing
 — Post-launch tuning and training

\*\*How It Works\*\*

1. Discovery — we map your goals, audience, and existing systems
 2. Prototype — a working demo you can test and share internally
 3. Refinement — iteration based on your feedback
 4. Launch & Training — deployment to your chosen channel plus a walkthrough so your team can manage it confidently

Clear milestones and video demos keep you informed throughout. Our average turnaround for a standard single-channel bot is one week.

\*\*Who This Is For\*\*

This service suits founders, product teams, customer-support leads, and marketing managers who need AI automation that actually works in production — not a no-code toy. If you run an e-commerce store, a SaaS platform, a fintech product, or any business fielding repetitive inbound queries or calls, a well-built AI agent will save your team significant time and cost.

\*\*Before You Order\*\*

Please message us with a brief description of your use case before placing an order on the larger tiers. This ensures we scope the work accurately and that your project is a strong fit. We will respond promptly and outline a clear plan.
