# coreAI chat widget: an AI chatbot that actually understands your customers

coreAI chat widget is an AI chatbot that pulls answers directly from your own sources – websites, documents, product catalogues, and APIs – and delivers precise, source-backed replies in real time. Unlike traditional chatbots with pre-programmed flowcharts, coreAI uses Retrieval-Augmented Generation (RAG) to formulate answers tailored to exactly what the customer is asking.

It is an intelligent AI assistant that combines advanced language understanding with your knowledge base, and it can be installed on your website in under five minutes.

## Unique benefits of the coreAI chat widget

### Real-time answers with source citations – no hallucinations

coreAI streams answers in real time, just like chatting with a human. But unlike general-purpose AI chatbots such as ChatGPT or Copilot, coreAI only retrieves information from your verified knowledge base. Every reply ships with clickable source citations so the customer can always verify the information. The result is a chatbot you can actually trust – with no risk of the AI making things up.

### Complete customisation – from appearance to language and behaviour

The coreAI chat widget adapts fully to your brand and your needs:

- Visual customisation: choose background colour, icon style (standard, sparkle, or custom icon), placement (all four corners or hidden), and fine-tune both vertical and horizontal offsets for pixel-perfect positioning.
- Multilingual support: the widget automatically detects the user's browser language and replies in the right language. Every text element – welcome message, buttons, progress messages, terms, and shopping-cart copy – can be customised per language.
- Behaviour configuration: control terms acceptance (once, every time, or never), enable source selection for users, include content from the page the customer is on, and configure auto-scrolling.
- E-commerce integration: enable a shopping list with support for multiple cart adapters so product recommendations in chat become direct sales channels.

## What makes coreAI chat unique compared with competitors?

### Intelligent context understanding with query rewriting

coreAI understands the context from the entire conversation history when a customer asks a follow-up question. The system uses AI-driven query rewriting to reformulate the question into a self-contained search – so "How much does it cost?" automatically becomes "How much does [the product the customer asked about] cost?". This gives far better hits in the knowledge base than chatbots that handle each question in isolation.

### Voice interaction and accessibility

The widget supports speech recognition so users can ask questions with their voice. With a WCAG-compliant design, coreAI chat is accessible to all users – regardless of ability.

### Lightweight integration without conflicts

The widget loads asynchronously and is isolated from the rest of the site, so it does not affect performance or clash with existing JavaScript frameworks. It works equally well on a static landing page and in an advanced headless storefront.

### Real-time feedback and learning

Every response can be rated by the user on three levels (poor, neutral, good), with the option to add written feedback. After a customer-service case is closed, the customer can give an overall satisfaction rating. This data provides continuous insight into what the chatbot is doing well – and where it can improve.

## Easy installation – up and running in minutes

Add the coreAI chat widget to your website with just a few lines of code. You manage everything – colours, placement, languages, source selection, and shopping-cart integration – directly from the coreAI portal, with no developer resources required. Changes take effect immediately, without redeploying the website.
