AI Chatbot Development for Websites, WhatsApp and Support Teams
RED SAG builds AI chatbots and WhatsApp automations that do specific jobs well: qualify leads, answer customer questions from your own documents, book appointments and send order updates. Our AI chatbot development services connect modern language models to your real systems, such as your CRM, booking calendar or order database, so the bot can act on requests instead of just chatting.
A good business chatbot knows its limits. We set clear boundaries on what it answers, ground replies in your approved content to reduce made-up answers, and hand the conversation to a person when a customer is frustrated or the question is outside scope. You get transcripts and simple analytics to see what customers are really asking.
Projects start small, usually with one channel and one high-volume use case, and expand once the results are clear.
Who AI Chatbots is for
Businesses drowning in repeat questions
Support teams answering the same pricing, delivery, policy and status questions every day on chat, email and WhatsApp.
Sales-led businesses that miss leads
Real estate, education, clinics, travel and service firms whose enquiries arrive after hours and go cold before anyone replies.
Appointment and booking businesses
Clinics, salons, restaurants, coaching centres and consultants who want customers to book, reschedule and get reminders without phone calls.
E-commerce and D2C brands
Online stores that want order tracking, cart recovery messages, returns requests and product recommendations handled on WhatsApp.
Features we build
Answers grounded in your content
The bot retrieves answers from your website, FAQs, PDFs, policy documents and product data using retrieval-augmented generation. It cites or links the source where useful and says it does not know rather than guessing.
WhatsApp Business API automation
Official WhatsApp Cloud API setup with a verified business number, approved message templates, interactive buttons and lists, catalogue messages and opt-in management. No grey-market tools that risk your number being banned.
A chatbot for lead generation
The bot asks the right qualifying questions in a natural way, scores the enquiry, and pushes the lead into your CRM, Google Sheet or email with the full conversation attached for your sales team.
Bookings and order updates
Customers check availability, book, reschedule or cancel inside the chat, with reminders sent automatically. Order confirmations, shipping updates and delivery notifications can be triggered from your store or ERP, and a WhatsApp ordering system lets customers pick items from your catalogue and place an order without leaving the chat.
AI agents that take actions
Beyond answering questions, agents can look up an order, create a support ticket, generate a quote or update a record through your APIs, with guardrails that limit what each action is allowed to do.
Human handover and shared inbox
When the bot is unsure or a customer asks for a person, the chat moves to a shared inbox where your team sees the full history and replies from the same number or widget.
Multilingual conversations
Support for English plus Hindi, Tamil and other Indian languages, or French and Spanish for international audiences, with language detection so customers can write the way they normally do.
Analytics and continuous tuning
Dashboards show conversation volumes, resolution rates, handover reasons and unanswered questions. We use this to improve answers and add content in the first months after launch.

Frequently asked questions
How much does AI chatbot development cost?
The AI chatbot price depends mostly on the channels and integrations involved. A starter bot that answers questions from your content and captures leads usually costs ₹30,000 to ₹90,000 (about $450–1,350). WhatsApp automations with bookings or CRM integration typically run ₹90,000–2.5 lakh. Custom AI agents cost more. On top of build cost, expect monthly usage charges for the AI model and WhatsApp conversations, which we estimate for you upfront.
What are the ongoing costs of running a chatbot?
There are three: AI model usage, charged by providers such as OpenAI or Anthropic based on volume; WhatsApp conversation or message fees charged by Meta, which vary by country and message category; and hosting. For most small and mid-sized businesses these add up to a modest monthly amount, and we set usage alerts so there are no surprises.
Will the chatbot make things up?
Language models can produce wrong answers, so we reduce the risk carefully. The bot answers from your approved content, is instructed to decline questions outside its scope, and hands over to a person when confidence is low. We test with real customer questions before launch and review transcripts afterwards. For prices or policies, answers come directly from your data.
Do I need the official WhatsApp Business API?
For automation at scale, yes. The official API through Meta's Cloud API lets you run bots, send approved template messages and connect multiple agents to one number. Unofficial tools that automate the regular WhatsApp app can get your number banned. Every WhatsApp chatbot development project we take on uses the official API, and we help with business verification, display name approval and template approvals.
Is customer data safe with an AI chatbot?
We use AI provider plans that do not train on your API data, encrypt stored conversations, restrict admin access and let you set retention periods. We can mask sensitive details such as phone numbers or ID numbers before they reach the model. Designs take the DPDP Act 2023, GDPR and UK GDPR into account for the regions you serve.
Can the chatbot connect to our CRM or booking system?
Yes. We regularly integrate with CRMs such as HubSpot, Zoho CRM and Salesforce, calendars like Google Calendar and Calendly, e-commerce platforms such as Shopify and WooCommerce, and custom databases through APIs. If your system has no API, we can often work with exports, webhooks or a small middleware service.
How long does it take to launch a chatbot?
A focused FAQ or lead-capture bot can be live in two to four weeks. WhatsApp automations need extra time for Meta business verification and template approvals, so four to eight weeks is typical. Agents that take actions in several systems take longer because of integration and testing work.
Can you build a chatbot for a business in the US, UK or Australia?
Yes. We are an AI development company in India working with clients in several countries, and the same approach works worldwide. We set up the bot for your time zone, currency and language, handle WhatsApp or website chat depending on what your customers use, and schedule calls in your working hours. Contracts, invoices and IP assignment are handled in USD, GBP, AUD or CAD as you prefer.
