Frequently Asked Questions

ChatNexus is an AI assistant builder that lets you create smart assistants trained on your own knowledge base. You can upload documents, paste text, or link URLs to give your assistant specific knowledge, then embed it on your website or share it with customers. It also includes built-in appointment scheduling. It is operated by CHISTY DIGITAL FORGE, a sole trader based in Sydney, NSW, Australia.

ChatNexus is built for individuals, small businesses, and teams that want to deploy AI-powered customer support, internal knowledge assistants, or specialised chatbots - without writing code. If you have information you want users to access through a conversational interface, ChatNexus is for you.

No technical skills are required. Creating and publishing an agent takes just a few minutes - you define the persona, upload your knowledge content, and your agent is ready. Embedding it on a website only requires pasting a single script tag.

You can add plain text, PDF documents, URLs (web pages), and Google Docs. The platform processes and indexes your content so the agent can retrieve relevant information when answering questions.

ChatNexus uses Retrieval-Augmented Generation (RAG). Your content is split into small chunks and stored as vector embeddings. When a user asks a question, the most relevant chunks are retrieved and passed to the AI model as context, so the agent answers based on your specific knowledge rather than general training data alone.

Yes. You can set a custom name, avatar, welcome message, and accent colour. You can also write a system prompt to define the agent's persona, tone, and behaviour. The embeddable chat widget inherits these customisations automatically.

From your agent's settings page, copy the provided embed snippet and paste it before the closing </body> tag of your HTML. The chat widget will appear automatically on your site. You can also share the public chat link directly with users.

ChatNexus supports multiple LLM providers including OpenAI (GPT-4o, GPT-4o mini), Groq (Llama 3, Mixtral), Google Gemini, and xAI (Grok). The available models depend on your subscription plan. You can select a preferred model per agent.
