What Our Developers Excel At
AI-Powered Ecommerce Chatbots
Chatbots that go beyond scripted FAQ trees. We build conversational AI agents that recommend products based on customer intent, handle size/variant questions, recover abandoned carts via WhatsApp, and escalate to human agents when the conversation needs a personal touch.
Chatwoot Deployment & Customisation
We deploy and customise Chatwoot as the open-source backbone for live chat and bot orchestration. Custom inboxes, agent assignment rules, canned responses, and webhook integrations — all self-hosted on your infrastructure for full data ownership.
n8n-Powered Bot Workflows
Every chatbot we build is orchestrated through n8n — our workflow automation platform of choice. This means your bot logic is visual, editable, and extensible without rewriting code. Add a new intent, connect a new API, or change the escalation rules — all in a drag-and-drop interface.
WhatsApp & Telegram Bots
We build production-grade bots for WhatsApp Business API and Telegram that handle order tracking, appointment booking, lead qualification, and customer support. Connected to your CRM, ecommerce platform, and internal systems via n8n workflows.
RAG Knowledge Bases
Retrieval-Augmented Generation pipelines that let your chatbot answer questions from your own documentation, product catalogue, or knowledge base. Built on pgvector for semantic search, with OpenAI or Claude as the generation layer. Your bot knows your business — not just the internet.
OpenAI & Claude Integration
We integrate both OpenAI GPT-4 and Anthropic Claude into chatbot workflows, choosing the right model for each use case. Claude for nuanced customer interactions and long-context understanding. GPT-4 for structured data extraction and function calling. We're model-agnostic — we pick what works.
## Why Hire an AI Chatbot Developer?
The chatbot market has split into two worlds. On one side, drag-and-drop tools that produce glorified decision trees — bots that feel robotic, frustrate customers, and get abandoned within weeks. On the other, genuine conversational AI that understands intent, retrieves accurate information from your business data, and handles complex multi-turn conversations that would otherwise require a human agent.
At Innovatrix Infotech, we build the second kind. Our Kolkata-based team deploys AI chatbots powered by OpenAI GPT-4 and Anthropic Claude, orchestrated through n8n workflows, and served through Chatwoot — an open-source customer engagement platform you fully own. The result is a chatbot that sounds human, knows your business, and runs on infrastructure you control.
## What Makes an AI Chatbot Different from a Traditional Bot?
Traditional chatbots follow scripts. You define every possible question and map it to a canned response. The moment a customer asks something outside the script, the bot fails. AI chatbots are fundamentally different — they use large language models to understand intent, generate contextual responses, and handle conversations that don't follow a predetermined path.
But raw AI isn't enough. An LLM without your business context will hallucinate product details, invent policies, and confidently give wrong answers. That's why every chatbot we build includes a RAG (Retrieval-Augmented Generation) pipeline — the AI retrieves relevant information from your product catalogue, help documentation, or knowledge base before generating a response. The bot knows your business, not just the internet.
## Our Tech Stack: Chatwoot + n8n + OpenAI/Claude
We've deliberately chosen an open-source-first stack that gives you full control over your chatbot infrastructure. Chatwoot handles the customer-facing layer — web chat widgets, WhatsApp Business API, Telegram, and email channels — all running on your AWS infrastructure. No per-conversation fees. No vendor lock-in.
n8n orchestrates the bot's intelligence. Every conversation flow, API call, and escalation rule is a visual workflow that your team can inspect, modify, and extend. When a customer asks about order status, n8n routes the query to your Shopify API, retrieves the order data, passes it to Claude for natural language formatting, and sends the response back through Chatwoot. The entire chain is visible and auditable.
For the AI layer, we're model-agnostic. OpenAI GPT-4 handles structured tasks well — extracting order numbers from freeform text, classifying customer intents, and calling external functions. Claude excels at nuanced customer conversations, long-context understanding, and scenarios where tone and empathy matter. We choose the right model for each conversation stage, not the most expensive one.
## Ecommerce Chatbots: Where AI Meets Revenue
Most chatbot agencies build generic support bots. We build ecommerce-native AI that directly impacts revenue. Product recommendation bots that suggest items based on conversational context. Cart recovery bots that send personalised WhatsApp messages when a customer abandons checkout. Order tracking bots that pull real-time status from Shopify or your OMS and communicate it in natural language.
Our ecommerce experience runs deep. We've built Shopify stores that generated ₹4.2L in launch-month revenue (Baby Forest), lifted mobile conversion by 41% (FloraSoul), and increased repeat purchases by 33% (Zevarly). That commercial context informs every chatbot we build — we don't just make bots that talk, we make bots that sell.
## WhatsApp Bots: Meeting Customers Where They Are
In India, UAE, and Southeast Asia, WhatsApp isn't just a messaging app — it's where commerce happens. We build WhatsApp Business API bots that handle lead qualification, appointment booking, order tracking, and customer support with AI-powered responses and seamless human handoff when needed.
Every WhatsApp bot we deploy connects through Chatwoot for agent oversight and n8n for workflow orchestration. Your support team sees every conversation, can jump in at any point, and the bot learns from the interactions it escalates. It's not a black box — it's a transparent, improvable system.
## Hiring an AI Chatbot Developer from Kolkata
Our Kolkata base means you get senior AI engineers and automation architects at a fraction of what a US or European agency charges — without the quality tradeoff. Every project is led by our founder, a former Senior Software Engineer who has personally deployed OpenAI and Claude integrations in production environments.
Innovatrix Infotech is DPIIT-recognised, MSME-certified, and an AWS Partner. We work with clients across India, UAE, UK, Australia, and Singapore with international invoicing, English contracts, and sprint reviews timed to your business hours. Whether you're a D2C brand looking for a WhatsApp sales bot or an enterprise exploring AI customer support, we're operationally ready from Day 1.

How it works
Our process — start to finish
Discovery Call (30 min)
We understand your business, your customer communication pain points, and where a chatbot fits into your stack. We'll tell you honestly whether AI adds value to your use case or whether a simpler solution is better.
Conversation Architecture
We map every conversation flow: user intents, bot responses, escalation triggers, and integration points. You review a visual conversation map in n8n before we write a single line of code.
Build & Integrate
Chatwoot deployment, n8n workflow build, OpenAI/Claude integration, RAG pipeline setup, and channel connections (web widget, WhatsApp, Telegram). Your dedicated bot engineer ships working code every sprint.
Test & Train
We test every conversation path with real scenarios, train the knowledge base with your documentation and product data, and fine-tune the prompt engineering for tone, accuracy, and escalation sensitivity.
Launch & Optimise
Go live on your chosen channels. Weekly conversation analytics show where the bot is performing, where it's failing, and what needs retraining. The bot gets smarter every week — not just at launch.
Typical timeline: 10 weeks
