-
1
Add your knowledge
Upload documents, paste text, or connect URLs. Your agent learns from your content — not generic web data.
-
2
Customize behaviour
Pick a system prompt, set the welcome message, choose colors, and enable built-in appointment scheduling for real actions.
-
3
Embed anywhere
Copy a script tag, install the WordPress plugin, or share a standalone link. Your agent is live in minutes.
Built for support, not for everything
ChatNexus is deliberately narrow. Here is exactly what that means.
What ChatNexus is
- A customer support assistant for one business at a time
- Answers built from the documents, FAQs and policies you upload
- Says "I don't have that information" instead of guessing
- Books appointments and captures enquiries 24/7
- Embeds on your site, or shares as a chat link
What ChatNexus is not
- Not a general-purpose chatbot — it will not answer questions outside your content
- Not a ChatGPT alternative for essays, code, research or homework
- Cannot generate or supply images, music, audio or video
- Does not browse the internet or search the web for answers
- Not for medical, legal or financial advice
If you need an assistant that answers from your own material, ChatNexus is built for that. If you need general-purpose AI, a consumer AI chat product is the better fit.
