LLM-Based Chatbots & AI Assistants

We build intelligent, secure chatbots powered by modern LLMs that understand your domain, speak your brand’s language, and integrate deeply into your workflows.

Website & in-app assistants
RAG & knowledge base integration
GDPR-conscious & production-ready

Beyond Simple Chat Widgets

Cognivox Labs designs LLM-based assistants that reliably answer questions based on your content, automate routine requests, and integrate with your systems. We combine retrieval-augmented generation (RAG), prompt engineering, and strong guardrails so your assistant is helpful, traceable, and safe to run in production.

Intelligent Support

Resolve repetitive support questions with human-like responses and instant access to your latest documentation.

Domain-Aware Answers

Use RAG pipelines to make sure responses are grounded in approved content, with citations where needed.

Integrated Workflows

Connect your assistant to CRMs, ticket systems, or internal tools to create tickets, update data, and trigger actions.

Where Our Chatbots Deliver Value

We focus on use cases where AI assistance directly reduces workload, increases conversion, or improves internal efficiency.

Customer support chatbots for websites & portals
Lead qualification and pre-sales assistants
Internal knowledge base assistants for teams
IT, HR, and policy self-service assistants
Form-filling and document generation copilots
Domain-specific legal, compliance, or tech advisors

Human in the Loop by Design

We never treat AI as a black box. Your chatbot can escalate to humans, log interactions, and provide transparency over what it answered and why.

Smooth handover to your support team with full history.
Continuous training based on real questions, not guesses.

Our Implementation Process

01. Strategy & Use-Case Definition

We identify where AI assistance creates real value: support, sales, internal helpdesk, or automation.

02. Knowledge & Data Design

We structure your content, documents, and APIs for retrieval-augmented generation (RAG) with quality control.

03. Conversation & UX Design

Designing flows, personas, and tone of voice so the chatbot feels aligned with your brand and users.

04. Implementation & Integration

We build the LLM backend, guardrails, and UI widget, integrate with your systems, and set up logging.

05. Evaluation & Fine-Tuning

Using real conversations, we refine prompts, retrieval, and flows to improve accuracy and usefulness.

We provide ongoing updates, new skills, security patches, and performance reports.
