Chatbot Development
GPT-powered chatbots for websites, WhatsApp, and customer support.
Overview
We build conversational AI that actually answers — not decision-tree bots that frustrate customers. BetaZen Infotech develops chatbots on GPT-class models with retrieval-augmented generation (RAG), so the bot responds from your real product docs, price lists, and policies. Deliverables include the trained knowledge base, a branded web widget or WhatsApp Business API integration, live-agent handoff, and an analytics dashboard showing what customers actually ask.
We are a Kolkata-headquartered team shipping chatbots for e-commerce stores, clinics, and institutes throughout West Bengal and pan-India, and our bots hold multilingual conversations for overseas clients too.

Why choose BetaZen
Answers at 2 a.m.
Your bot resolves pricing, availability, and policy questions around the clock, so no enquiry waits for office hours.
Grounded, not hallucinating
RAG keeps replies pinned to your approved content, with citations and a strict fallback when the answer isn’t known.
Every chat becomes a lead
Name, phone, and intent are captured mid-conversation and pushed straight into your CRM with full context.
How we work

We design the experience and the system architecture up front so what we build scales cleanly and predictably.
Agile Delivery
We ship in short, reviewable increments with continuous testing so you see working software early and often.
Launch & Support
We handle deployment, monitoring, and handover — and stay on to iterate, optimize, and support post-launch.
Frequently asked questions
Can the chatbot reply in Bengali and Hindi?
Yes. We regularly deploy trilingual bots for West Bengal businesses that switch between Bengali, Hindi, and English based on how the customer writes. Language quality is tested with native speakers before launch.
What does chatbot development cost in India?
A website FAQ bot typically starts around a modest fixed fee, while WhatsApp bots with CRM integration and RAG cost more depending on knowledge-base size. We quote a flat INR price after a short scoping call — no per-message surprises beyond model usage.
How does the bot hand over to a human?
When confidence drops or the customer asks for a person, the bot transfers the full transcript to your support inbox, WhatsApp agent, or helpdesk tool. Nothing gets lost in the handoff.
Will the bot stay accurate as our catalog changes?
The knowledge base syncs from your website, sheets, or CMS on a schedule you choose, and we include monthly reviews of unanswered questions so coverage keeps improving.
