AI Chatbot MVP Development: A Custom Chatbot Your Customers Actually Use
We build AI chatbot MVPs that answer customer questions from your content, capture leads and hand off to your team when needed, on your website, inside your app or on WhatsApp. Fixed price from $5,000, delivered in 1–5 weeks with full IP transfer.
Codersarts builds custom AI chatbot MVPs for businesses that want a chatbot they own instead of renting one. Our chatbots answer customer questions from your FAQs, website, help center and product data, capture leads, and hand conversations to your team in your help desk or Slack when they can't help. They run as a website widget, inside your web or mobile app, or on WhatsApp. Pricing is fixed: $5,000–$9,000 for a starter chatbot trained on your FAQs and site content (1–2 weeks), and $8,000–$15,000 for a knowledge chatbot that answers from your documents with citations, human handoff and analytics (3–5 weeks). Chatbots that need to book, update orders or take other actions become AI agents, from $15,000. Every build includes brand voice and guardrails, evaluation on real customer questions, conversation analytics, cost controls, and full source code and IP transfer, with no per-seat or per-resolution platform fees.

Quick Answer
An AI chatbot MVP is the first working version of a custom chatbot that answers your customers from your own content, on the channels they already use.
At Codersarts, it costs $5,000–$9,000 for a starter chatbot trained on your FAQs and website (1–2 weeks), or $8,000–$15,000 for a knowledge chatbot that answers from your documents with citations, human handoff and analytics (3–5 weeks).
If the chatbot needs to take actions, like booking appointments or updating orders, it becomes an AI Agent MVP Development (from $15,000).

When You Don't Need a Custom Chatbot
A chatbot platform already covers it and its fees fit your budget.
You get very few questions. Under about 50 a month, a good FAQ page may be enough.
There is no content to answer from yet. Write the FAQs and help articles first.
Frequently Asked Questions
How much does a custom AI chatbot MVP cost?
$5,000–$9,000 for a starter chatbot trained on your FAQs and website content, and $8,000–$15,000 for a knowledge chatbot that answers from your documents with citations, human handoff and analytics. Chatbots that take actions become AI agents, from $15,000.
How long does it take to launch an AI chatbot?
1–2 weeks for a starter chatbot and 3–5 weeks for a knowledge chatbot with handoff and analytics.
Can the chatbot work on WhatsApp?
Yes. We connect to the WhatsApp Business Platform, alongside a website widget or in-app chat if needed. WhatsApp messaging fees are billed separately by Meta.
Can it be trained on our website and documents?
Yes. We ingest your website, FAQs, help center, PDFs and product data, and the chatbot answers from that content instead of making things up.
Can it hand conversations to a human?
Yes. When the chatbot can't help, or the customer asks, it hands off with the full transcript to email, Slack or help desks such as Zendesk, Intercom or Freshdesk.
How do you stop the chatbot giving wrong answers?
It answers only from your approved content, says when it doesn't know, never invents prices or policies, and is tested on real customer questions before launch. Conversation analytics show any gaps to fix.
What are the monthly costs?
There are no per-seat or per-resolution platform fees. You pay only running costs, typically $50–$300 per month for up to about 2,000 conversations.
Why build a custom chatbot instead of using a chatbot platform?
A platform is quicker if it covers your needs. A custom chatbot makes sense when you need deeper integrations, your own data controls, custom UI, or when platform fees grow with volume. You own the code and pay no subscription.
