Our approach

How do we approach AI chatbots?

A useful chatbot is built on good content. We first gather the sources it should answer from — help articles, policies, product information and past conversations — and identify the gaps, because a bot can only be as accurate as what it is given.

We design the conversation flows that matter most, such as order status, bookings or lead capture, and define clearly when the bot should hand over to a person. The bot is tested against a set of real questions and its answers are reviewed before launch.

After launch, your team reviews conversations in a simple dashboard. Unanswered questions show where content needs improving, and we tune the bot regularly so answers stay accurate as your products and policies change.

What affects the cost and timeline?

  • The channels: website, WhatsApp, mobile app or several at once
  • The volume and quality of the content the bot answers from
  • Actions beyond answering, such as order lookups, bookings or CRM updates
  • Languages supported, including Indian regional languages
  • Handover to human agents and the help-desk tool your team uses

Typical timeline: 3–8 weeks. After a short discovery call we confirm scope and give you a written estimate.

FAQ

AI Chatbots FAQ

Didn't find your answer? Ask us directly →

How is an AI chatbot different from a rule-based bot?

A rule-based bot follows fixed scripts. An AI chatbot understands natural language and answers from your knowledge base, so it handles far more questions without every path being scripted.

How do you stop a chatbot from giving wrong answers?

We ground answers in approved content, restrict out-of-scope topics, show sources where useful, test with real questions and route uncertain cases to a person.
