ChatAgent - AI Chatbot Plugin for Craft CMS

ChatAgent is a powerful AI chatbot plugin for Craft CMS that lets you train a smart assistant on your own content and deploy it directly on your website - without any third-party chat platform. Feed it your Craft entries, uploaded files, URLs, or custom Q&A pairs, and your visitors get instant, accurate answers based on your actual content.

Requirements

Craft CMS 5.9.0 or later
PHP 8.2 or later
OpenAI API Key

Installation

From the Plugin Store

Go to the Plugin Store in your project's Control Panel and search for "ChatAgent". Then press Install.

Setup

After installation, go to Chatbot → Settings → General and enable the chatbot. The widget is disabled by default and will not appear on the frontend until you toggle it on.

No template changes are required. Once enabled, the widget is automatically injected before </body> on every frontend page.

If you prefer manual placement (e.g. only on specific pages), add {{ chatbotWidget() }} to your template. The plugin detects this and will not inject the widget a second time.

Training Your Chatbot

The chatbot's knowledge comes entirely from content you provide. You can train it from four different sources, all accessible under Chatbot → Training in the Control Panel.

Craft Entries

Train the chatbot on your existing Craft CMS content in just a few clicks.

Select which sections the chatbot should learn from
Click "Train now" to index all entries from the selected sections
Each entry is split into chunks and stored as vector embeddings
A table shows every indexed entry with its chunk count and last training date
Individual entries can be re-trained or removed from the index
Click into an entry to inspect its chunks and see exactly what the AI knows

File Upload

Upload plain-text documents directly to the training index.

Supports .txt and .md files (max 5 MB each)
Drag-and-drop or click to browse
Files are indexed immediately after upload
Manage uploaded files in a table: re-index or delete individual files

URL / Sitemap Training

Point the chatbot at any public webpage or import an entire sitemap at once.

Paste a sitemap XML URL to automatically discover and import all pages
Or enter individual URLs manually (one per line)
Click "Crawl all & index" to process all queued URLs
Each URL shows a status badge: pending, indexed, or error
Click into a URL to inspect its extracted chunks
Re-crawl or delete individual URLs at any time

Q&A Training

Define exact question-and-answer pairs to give the chatbot precise, reliable responses to common questions.

Add pairs manually via a simple form (question + answer)
Or import directly from Chat Logs - turn any real bot response into a training pair with one click
Toggle pairs active / inactive without deleting them
Pairs show their source: Manual or Log
Saved pairs are immediately indexed and available to the chatbot

Dashboard

The Dashboard gives you a live overview of how your chatbot is being used and what it knows.

Conversation Statistics

Total Conversations - number of chat sessions
Total Messages - all messages sent and received
Average Response Time - bot latency in seconds
Average Conversations per Day
Positively Rated / Negatively Rated messages (when ratings are enabled)

Filter all stats by date range using the date picker or quick presets (Last 7 days, Last 30 days, Last 90 days). Stats refresh instantly without a page reload.

Activity Chart

An interactive line chart shows conversation and message volume over time - helpful for spotting peaks or drops in chatbot usage.

Suggestion Statistics

See which preset questions your visitors click most, with usage counts per suggestion.

Training Data Summary

Indexed entry count, chunk count, sections, and last training date
Indexed file count, chunk count, and last indexing date

Chat Logs

Every conversation is stored and fully accessible under Chatbot → Chat Logs.

Session List

Browse all chat sessions in a filterable, paginated table.

Filter by:

Search by session ID
Rating (All, Positive, Negative)
Confidence level (High ≥ 80%, Medium 60–79%, Low < 60%, No context)

Each row shows:

Session ID, page URL, message count
Rating summary (thumbs up / down ratio)
Color-coded confidence badge
IP address and timestamp

Bulk Delete

At the bottom of the logs page, two bulk delete options are available:

Delete before date - select a date and delete all sessions up to and including that day
Delete all sessions - remove the entire log history at once

Both actions require confirmation and cannot be undone.

Session Detail View

Click any session to see the full conversation.

Every message shows its role (User or Bot), timestamp, and response time
Bot messages display a confidence score badge (color-coded)
If the user rated a message, a thumbs up (green) or thumbs down (red) icon is shown
Messages used as Q&A training sources are marked with a "✓ Q&A Training" badge
A "Use as Q&A" button is available on every bot message - one click creates a new training pair

Color Grading

Confidence scores are color-coded throughout the log views for instant visual scanning:

Score	Color	Meaning
≥ 80%	Green	High confidence - strong context match
60–79%	Yellow	Medium confidence
< 60%	Red	Low confidence - weak or partial context
-	White	No context used

Confidence Score

Every bot response is automatically assigned a confidence score between 0 and 1, based on how closely the retrieved context matches the user's question.

Displayed as a color-coded percentage badge on each message
Visible in the session list and the full session detail view
Configurable minimum similarity threshold (Settings → AI Configuration)
Low-confidence responses can be reviewed and improved by adding targeted Q&A pairs

Thumb Up / Down User Ratings

Visitors can rate individual bot responses directly in the chat widget.

Thumbs up / down buttons appear below each bot response (when enabled in Settings → Logging)
Ratings are stored per message and visible in Chat Logs
Aggregated rating counts appear in the Dashboard
Filter Chat Logs by rating to quickly find poorly received answers

Auto-Train on Entry Save

When this feature is enabled (Settings → Training), any entry saved in the Craft Control Panel is automatically indexed in the background - no manual training needed.

Works for all sections selected for training
Creates a background queue job on every entry save
Keeps your chatbot's knowledge current as you update content
Can be toggled off at any time without losing existing index data

Queue Manager Support

Long training operations (large sitemaps, many entries) run as background jobs via Craft's built-in Queue system.

Training and crawl jobs are queued automatically
The UI shows how many jobs were queued and links to Utilities → Queue
No blocking of the Control Panel during processing
You can continue working while training runs in the background

Settings & Customization

All settings are under Chatbot → Settings, organized in tabs.

General

Setting	Description
Enable Chatbot	Show or hide the widget on the frontend
Logo Text	Up to 3 characters, shown as a badge if no logo image is set
Logo Image	Square image (min 80×80 px) used as the chat avatar
Primary Color	Color for buttons and user message bubbles
Logo Background Color	Background color behind the logo in the chat header
Default Theme	Start in Light or Dark mode
Input Placeholder	Placeholder text inside the message input field (default: `Your message...`)
Send Button Text	Label on the send button (default: `Send`)

Company

Setting	Description
Company Name	Displayed in the chat header
Website URL	The main URL of your website
About the Company / Website	Short description of what your company does, its products/services, and target audience

Company name, website URL, and description are automatically prepended as a context block to the system prompt so the AI understands who it is representing.

AI Configuration

Setting	Description
OpenAI API Key	Required for all AI functions
Chat Model	`gpt-4o-mini` (recommended), `gpt-4o`, or `gpt-3.5-turbo`
Embedding Model	`text-embedding-3-small` (recommended), `-large`, or `ada-002`
Initial Message	The bot's first greeting when the chat opens
System Prompt	Full instructions / persona for the AI - define tone, language, scope, restrictions. Pre-filled with a sensible default on first use - edit and save it here in the backend.
Max Context Chunks	How many matching text chunks are passed as context (1–20, default 5)
Min Similarity Score	Minimum relevance threshold for context retrieval (0.00–1.00, default 0.65)

Note: Switching the embedding model requires full retraining of all content.

Default System Prompt

On a fresh install, the System Prompt field is pre-filled with the contents of default-prompt.md (included in the plugin). This gives users a working starting point without having to write a prompt from scratch. Once saved in the backend, the stored value is used exclusively - the file is no longer consulted.

Training

Select which Craft sections are included in training
Enable or disable Auto-Train on Entry Save

Suggestions
