FAQ

Common questions

An AI chatbot is a software application that uses large language models (LLMs) like GPT or Claude to understand and respond to user messages in natural language. Unlike rule-based bots that follow fixed scripts, AI chatbots understand intent, handle unexpected questions, and maintain conversation context. We build custom AI chatbots trained on your specific business data so they know your products, policies, and workflows - not just generic answers.
A RAG (Retrieval-Augmented Generation) chatbot connects the AI to your own documents, PDFs, knowledge base, or database using a vector search system. When a user asks a question, the chatbot first retrieves the most relevant content from your data, then generates an accurate, cited answer. This eliminates hallucinations and ensures the chatbot only answers from your verified content. We build RAG chatbots using Qdrant for vector storage and LangChain for orchestration - ideal for support bots, internal knowledge assistants, and document Q&A systems.
A LangChain chatbot uses the LangChain framework to connect an LLM to external tools, APIs, memory, and data sources. LangChain handles the orchestration layer - managing conversation history, tool calling, document retrieval, and multi-step reasoning. We use LangChain to build chatbots that go beyond simple Q&A: they can search your CRM, look up orders, trigger workflows, and take actions on behalf of users.
A chatbot responds to messages in a conversation. An AI agent is autonomous - it can plan, use tools, call APIs, make decisions, and complete multi-step tasks without human intervention. For example, a chatbot answers 'What is your return policy?' An AI agent can process the return, update your inventory system, issue a refund, and send a confirmation email - all triggered by a single user message. We build both depending on your automation needs.
Yes - we build custom ChatGPT-powered chatbots trained on your specific business data, products, and FAQs. Unlike the generic ChatGPT interface, your custom chatbot knows your business, stays on-topic, integrates with your CRM, and can be deployed on your website, WhatsApp, or Slack in 2–4 weeks.
Yes. We build chatbots that read from and write to Salesforce, HubSpot, Pipedrive, and custom CRMs. The chatbot can qualify leads, create contacts, update deal stages, and trigger workflows - all automatically during the conversation.
We build AI chatbots and agents for healthcare (HIPAA-compliant patient intake and support), legal firms (document review and client intake), e-commerce (product recommendations and order support), fintech (account queries and fraud alerts), and SaaS companies (onboarding and customer success automation).
