AI CHATBOTS & VOICE— 30+ AI ASSISTANTS DELIVERED
Marketing Wise

AI chatbots and voice assistants built for Indian businessWe build conversational AI for clients based in Noida, Delhi & NCR, India

Marketing Wise has delivered 30+ AI chatbot and voice assistant projects since 2022 — customer service bots for eCommerce brands handling 1,800 daily queries, internal IT helpdesks for BPOs with 3,000+ employees, lead qualification voice assistants for real estate developers, and IVR replacement systems for service businesses. Every system is trained on client-specific knowledge — product catalogues, policy documents, support history — not a generic out-of-the-box model that answers confidently and incorrectly.

We use RAG (retrieval-augmented generation) to ground every response in your actual documentation. The AI retrieves relevant content before generating an answer, so responses are accurate and sourced — not hallucinated. We configure confidence thresholds that trigger seamless escalation to a human agent when the bot reaches the edge of its knowledge, and conversation analytics that show you exactly where drop-offs, fallbacks, and low-confidence responses are occurring so the system improves continuously.

  • RAG-powered knowledge base with document ingestion
  • Hindi and Indian English language understanding
  • WhatsApp Business API integration
  • CRM handoff (HubSpot, Salesforce, Freshdesk)
  • Voice assistant with IVR replacement capability
  • Conversation analytics and fallback monitoring
Can the chatbot understand Hindi and Indian English queries?
Yes. We test all chatbots extensively against Hindi, Hinglish, and Indian English variations. For multilingual deployments, we support Hindi, Tamil, and Marathi in addition to English, using language-appropriate embeddings and retrieval.
How is the chatbot trained on our product or service knowledge?
We use RAG — your product catalogues, FAQs, policy documents, and support tickets are indexed into a vector database. The LLM retrieves the most relevant chunks before generating each response, ensuring answers are grounded in your actual content.
Can the bot escalate to a human agent when it cannot help?
Yes. We configure confidence thresholds and topic filters that trigger seamless handoff to a human agent via Freshdesk, Intercom, Zendesk, or your preferred live chat tool. Full conversation context transfers so the agent does not ask the customer to repeat themselves.
Can you integrate the chatbot with WhatsApp Business?
Yes. We integrate via the WhatsApp Business Platform API (Meta). The bot can receive and respond to messages, send structured messages and interactive buttons, manage conversation sessions, and hand off to a live agent within the same WhatsApp thread.
What does a voice assistant replace in a call centre?
A voice assistant handles inbound call routing, FAQ responses, appointment booking, order status queries, and basic support. It replaces the IVR menu tree with natural language understanding, reducing call handle time and deflecting a significant share of volume away from live agents.
How do you prevent the chatbot from giving wrong or hallucinated answers?
RAG grounds every response in your indexed documentation. We also set citation requirements — responses include the source document and section. If no relevant source is found, the bot acknowledges it does not know and escalates rather than fabricating an answer.
Can the chatbot handle order tracking and real-time data queries?
Yes. We build tool-calling integrations that let the bot query live data — order status from Shopify or custom OMS, ticket status from Freshdesk, appointment availability from your calendar — and return real-time answers rather than static FAQ responses.
Can one chatbot handle multiple use cases — customer service, sales, and HR?
Yes. We build multi-intent bots with routing logic that directs queries to the appropriate knowledge base and response style. Each intent has its own RAG index, escalation path, and tone configuration while sharing a single conversation interface.
How long does it take to build and deploy an AI chatbot?
A standard RAG chatbot with website widget, one CRM integration, and knowledge base ingestion takes 6–10 weeks. WhatsApp integration, voice capability, or multi-language support extend this to 10–14 weeks.
How do you measure the success of a chatbot deployment?
We baseline containment rate (queries resolved without human), first-response time, escalation rate, and CSAT before and after deployment. We provide a monthly analytics report for the first 3 months so you can track improvement and tune the system.

Step by stepStep by step

Our process

No mystery phases. Four gates every AI chatbot engagement crosses — from knowledge audit to production deployment.

Knowledge audit & use case scoping

We audit your support tickets, FAQs, product docs, and policy documents to define what the bot will and will not handle. Escalation logic, tone, and language requirements are agreed before build starts.

Day 0

RAG pipeline & integrations

Documents are chunked, embedded, and indexed into the vector store. CRM, WhatsApp, and helpdesk integrations are wired. The bot is tested against 200+ real historical queries before any user sees it.

Week 1–3

Supervised rollout

Bot goes live to a small traffic segment. Every conversation is reviewed for containment rate, fallback frequency, and accuracy. Retrieval tuning and prompt refinement happen weekly.

Core weeks

Full deployment & analytics handoff

Full traffic rollout, conversation analytics dashboard, monthly review cadence for the first 3 months, and a documented process for adding new knowledge to the RAG index.

Our Diverse Development SolutionsOur Diverse Development SolutionsSince 2014
[01]Custom Web Applications
We architect and build bespoke web applications from first principles — SaaS platforms, multi-role operational dashboards, customer and vendor portals, ERP systems, booking engines, and data-intensive workflow tools. Every system is designed around your exact business logic and data model, not a template. Stack: React / Next.js frontend, Node.js or Python backend, PostgreSQL or MongoDB, deployed on AWS or GCP with CI/CD from day one.
[02]API & System Integrations
We design and implement secure, production-grade integration layers that connect your new application to your existing stack. Tally ERP, Salesforce CRM, Razorpay, WhatsApp Business API, Shiprocket, Google Workspace, Zoho, SAP — if it exposes a REST or GraphQL endpoint, we wire it in. We build middleware layers, webhook handlers, and real-time sync pipelines so your data flows without double entry or manual reconciliation.
[03]Cloud & DevOps Engineering
We provision, configure and manage right-sized cloud infrastructure on AWS, GCP or Azure — auto-scaling groups, managed databases (RDS, Cloud SQL, Atlas), CDN delivery, container orchestration with Docker and Kubernetes, and CI/CD pipelines via GitHub Actions or GitLab CI. Every environment ships with uptime monitoring, alerting, automated backups and a documented runbook. We target 99.9%+ uptime SLAs as a baseline, not a premium.
[04]Mobile & Cross-Platform Apps
We build React Native and Flutter applications that share the same backend APIs as your web platform — giving you iOS, Android and web coverage from a single, unified codebase. Features include offline support with local data sync, push notifications, biometric authentication, payment gateway integration, and submission to both the App Store and Google Play. One deployment pipeline, consistent data across every device.
[05]AI & Intelligent Automation
We build production-grade AI-powered applications: RAG pipelines over private document corpora, LLM-integrated workflow tools using the OpenAI and Anthropic APIs, agentic orchestration layers using MCP and n8n, and intelligent data extraction and classification systems. We do not bolt AI onto existing apps as a feature — we architect it as a core system component with proper context management, fallback logic, audit trails and cost controls.
[06]Legacy Modernisation & Audits
We take over underperforming, insecure or unmaintainable codebases and make them production-safe. Our audit process covers code quality, OWASP security vulnerabilities, performance bottlenecks, dependency staleness, database schema health and infrastructure risk. From there we stabilise, refactor and migrate — moving monoliths to modular architectures, upgrading stacks, replacing brittle third-party dependencies and restoring test coverage — so the codebase is ready for new features without accumulating further technical debt.
CASE STUDIES

AI assistants we have built
for businesses in Noida & Delhi NCR

01D2C eCommerce

AI customer service chatbot for a Noida health & beauty brand handling 1,800 daily queries

Agent support load reduced 64%. First-response time dropped from 4 hours to under 10 seconds.

Problem

The brand's support team of 12 was overwhelmed with repetitive order status, return policy, and product ingredient queries. Response times were hurting Flipkart and Amazon ratings.

Solution

We built a RAG chatbot trained on their product catalogue, policy PDFs, and 6 months of support tickets. It integrates with Shopify and the Shiprocket API for live order status. Complex queries escalate to a Freshdesk ticket.

Stack

Claude Haiku, Pinecone, Node.js, Shopify API, Shiprocket API, Freshdesk API

02Real Estate

Lead qualification voice assistant for a Delhi NCR real estate developer

Qualified leads to sales team increased 2.8x. Phone lead response time reduced from 8 hours to instant.

Problem

The developer's sales team was missing incoming calls after hours and during peak volumes. Leads from portals like 99acres were going cold before follow-up.

Solution

We built a voice assistant that answers inbound calls, asks qualification questions (budget, timeline, bedroom requirement), records answers in the CRM, and books site visits for interested prospects.

Stack

Twilio Voice, OpenAI Realtime API, Node.js, HubSpot API, Calendly API

03HR & Internal

Internal IT helpdesk bot for a Gurugram BPO company with 3,200 employees

IT ticket volume reduced 47%. Average resolution time for routine requests cut from 4 hours to 8 minutes.

Problem

The IT helpdesk was flooded with repeated queries: password resets, VPN access, software installation requests, and printer troubleshooting. Tier-1 tickets consumed 60% of IT team capacity.

Solution

We built an internal helpdesk bot trained on their IT runbooks and connected to Active Directory for self-service password resets and access provisioning. It creates Jira tickets for unresolved issues automatically.

Stack

Claude Sonnet, RAG/Pinecone, Node.js, Active Directory API, Jira API, Microsoft Teams

Custom Web App Development — Marketing Wise Noida

Top Rated Full StackSoftware Developers
in Noida, Delhi, NCR & India

RAG-powered AI chatbots and voice assistants for customer service and internal helpdesks in Delhi NCR.

Marketing Wise builds custom AI chatbots and voice assistants for businesses in Noida and Delhi NCR — trained on your product knowledge, integrated with your CRM and WhatsApp, and tested against Hindi and Indian English queries. Our systems use retrieval-augmented generation to give accurate, grounded responses and escalate gracefully when confidence is low.

How much does a custom AI chatbot cost to build?

A standard AI chatbot with RAG knowledge base, website integration, and CRM handoff starts at ₹5 lakhs. WhatsApp integration, voice capability, or multilingual support each add ₹2–5 lakhs.

What is the difference between a rule-based chatbot and an AI chatbot?

Rule-based chatbots follow decision trees and fail on unexpected input. AI chatbots understand natural language, retrieve relevant knowledge from your documentation, and generate contextual responses — far more flexible and far less frustrating for users.

Can the chatbot handle queries in Hindi?

Yes. We test all chatbots against Hindi and Hinglish queries and tune the retrieval pipeline for Indian language understanding. Full Hindi deployments use Hindi-optimised embeddings and language-specific prompting.

How long does it take to build and deploy a chatbot?

A standard chatbot with RAG knowledge base, website widget, and one CRM integration takes 6–10 weeks. WhatsApp, voice, or multilingual deployments run 10–14 weeks.

Can the chatbot integrate with our existing CRM and helpdesk?

Yes. We integrate with HubSpot, Salesforce, Freshdesk, Zendesk, and Intercom. Escalations transfer full conversation context so your agents never ask the customer to start over.
