Frequently Asked Questions

How much does AI chatbot development cost?

Rule-based chatbots cost $3,000-$8,000. AI-powered chatbots using GPT-4 or Claude cost $10,000-$30,000. RAG-enhanced chatbots with custom knowledge bases cost $20,000-$60,000. Voice bots cost $25,000-$70,000. Ubikon provides fixed pricing with no hidden fees.

What is the difference between rule-based and AI chatbots?

Rule-based chatbots follow predefined decision trees and can only handle anticipated questions. AI chatbots use LLMs like GPT-4 to understand natural language, maintain conversation context, and generate relevant responses to any question, including ones never seen before.

Can you build a chatbot that uses our company data?

Yes, using RAG (Retrieval-Augmented Generation), we build chatbots that answer questions from your documents, databases, and knowledge bases. Documents are chunked, embedded, and stored in a vector database. At query time, relevant information is retrieved to generate accurate, cited answers.

How long does chatbot development take?

A basic rule-based chatbot takes 2-4 weeks. AI-powered chatbots take 6-10 weeks. Enterprise RAG chatbots with custom integrations take 10-16 weeks. Voice bots take 12-20 weeks. We deliver a working prototype within the first 2-3 weeks.

Can the chatbot integrate with our existing systems?

Yes, we integrate chatbots with CRMs (Salesforce, HubSpot, Zoho), helpdesks (Zendesk, Freshdesk, Intercom), messaging platforms (WhatsApp, Slack, Teams), and any system with an API. We also build custom integrations for proprietary systems.
