In short
Dinoustech is an AI chatbot development company that builds custom GPT-powered chatbots for websites, mobile apps, WhatsApp and Instagram. Our chatbots are trained on your own documents and data, answer with sources, capture leads into your CRM, check orders and bookings through your APIs, and hand complex chats to a human. A standard AI chatbot goes live in 3 to 6 weeks.
The basics
How a modern AI chatbot actually works
Old chatbots followed fixed menus and broke as soon as a customer typed something unexpected. A modern AI chatbot uses a large language model to understand any wording, and retrieval-augmented generation (RAG) to answer only from your approved content: product pages, price lists, policies, manuals and past tickets.
Because the bot is connected to your systems, it can do more than talk. It can look up an order, check a delivery slot, create a support ticket, collect a phone number for sales or take a booking, and it knows when to pass the chat to a person with the full conversation attached.
The result is faster answers for customers, fewer repetitive questions for your team and a steady flow of qualified leads, including outside office hours when many enquiries arrive.

Pricing
AI Chatbot Development Cost
Most of the cost comes from integrations and channels, not the chat itself. These starting prices give a fair idea; the free plan gives an exact quote.
| Scope | What you get | Timeline | Starting from |
|---|---|---|---|
| Knowledge chatbot | Website widget, trained on your content, lead capture, admin panel | 3-4 weeks | $4,000 |
| Business chatbot | Website + WhatsApp, CRM and order/booking integration, analytics | 5-7 weeks | $10,000 |
| Enterprise assistant | All channels, voice, multilingual, SSO, private hosting, live-agent hand-off | 8-12 weeks | $22,000 |
WhatsApp Business API message fees and AI model usage are billed at actual cost. For most businesses they are a small fraction of a support agent's salary.

FAQs
AI Chatbot Development FAQs
How much does AI chatbot development cost?
A custom AI chatbot trained on your content usually starts around $4,000 and goes live in 3 to 4 weeks. A business chatbot with WhatsApp, CRM and order or booking integration starts around $10,000, and an enterprise multilingual assistant with voice starts around $22,000. Model and WhatsApp message fees are extra at actual cost.
Can you build a chatbot like ChatGPT for my business?
Yes. We use the same class of large language models as ChatGPT, such as GPT, Claude or Gemini, but connect them to your own knowledge base and systems so the bot answers only about your business, with your tone and rules.
Will the chatbot give wrong answers?
We reduce this with retrieval-augmented generation, which makes the bot answer only from your approved content and show sources, plus clear rules for topics it must not answer. When it is not sure, it says so and offers a human. We test with hundreds of real questions before launch.
Can the chatbot work on WhatsApp?
Yes. We build on the official WhatsApp Business API, so the bot can answer questions, send order updates, share catalogues, collect payments and hand chats to your team inside a shared inbox.
How long does it take to build an AI chatbot?
A knowledge chatbot for your website takes about 3 to 4 weeks. Bots with WhatsApp and system integrations take 5 to 7 weeks, and enterprise assistants with voice and many languages take 8 to 12 weeks.
Can the chatbot capture leads and send them to my CRM?
Yes. The chatbot can ask qualifying questions, collect name, phone and email, and push the lead into HubSpot, Zoho, Salesforce, Google Sheets or your own admin panel, with an instant alert to your sales team.
