AI Chatbots That Actually Work for Indian Businesses
WhatsApp bots, customer support agents, and LLM-powered assistants — built to handle Hinglish, scale to thousands, and integrate with your existing systems.
The Problem
Your customers are on WhatsApp, not your website. You're losing leads because nobody answers after business hours. Generic chatbot platforms don't understand Hinglish, can't integrate with your CRM, and charge per-message fees that kill your margins. You need a custom solution that feels like talking to a real person.

Frequently Asked Questions
How much does WhatsApp Business API cost?
WhatsApp Business API itself is free to set up through providers like Twilio or Meta directly. You pay per conversation: business-initiated messages cost ~$0.05-$0.10 per conversation (24-hour window), while user-initiated conversations are cheaper. For most small businesses handling 500-2000 conversations/month, expect $50-$200/month in messaging costs on top of the development cost.
Should I use an LLM or rule-based chatbot?
Start rule-based if your use case has clear, predictable flows (appointment booking, order status, FAQs). Go LLM-powered if you need the bot to handle open-ended questions, understand context across messages, or deal with unpredictable inputs. A hybrid approach works best for most businesses: rule-based for structured flows, LLM for everything else.
What are the ongoing costs after the chatbot is built?
Ongoing costs include: WhatsApp API messaging fees ($50-$200/month for small businesses), server hosting ($20-$50/month on AWS), and LLM API costs if applicable ($30-$300/month depending on volume). I design systems to minimize LLM calls using caching and rule-based pre-filtering, keeping costs predictable.
