Description
Plug ChatBot is an AI-powered chatbot plugin for WordPress. Version 2.0.1 adds xAI Grok alongside the existing OpenAI integration.
The site administrator can configure both providers and select one active chat provider. OpenAI and Grok Knowledge Bases are managed separately so files are sent only to the selected provider.
Current plugin capabilities include:
- OpenAI and xAI Grok chat integrations
- Provider-specific conversation state
- OpenAI Vector Store Knowledge Base management
- xAI Collection Knowledge Base management
- File Search and Code Interpreter controls per provider
- Custom bot identity, tone, and guardrail prompt
- Visitor capture before chat
- Optional chat history saved in WordPress
- Admin email notifications for chat transcripts
- Optional OpenAI Text-to-Speech responses
- Responsive chat widget customization
- Adjustable rate limiting

FAQ
-
Do I need both OpenAI and xAI API keys?
-
No. Configure the provider you want to use for chat. Both can be saved so the active provider can be changed later.
-
Which Grok models are available?
-
The plugin allows only these model IDs:
- grok-build-0.1
- grok-4.3
- grok-4.20-multi-agent-0309
- grok-4.20-0309-reasoning
- grok-4.20-0309-non-reasoning
-
Why is a separate xAI Management API key required?
-
The standard xAI API key is used for chat and file upload. xAI requires a Management API key for Collection creation and document attachment or removal.
-
Does Grok use the OpenAI Knowledge Base?
-
No. OpenAI Vector Stores and xAI Collections are separate. Upload a file under the provider tab that should use it.
-
Does Grok provide the voice response?
-
Not in version 2.0.1. The existing voice feature continues to use OpenAI Text-to-Speech and requires a saved OpenAI API key.
-
Does this plugin send data to external services?
-
Yes. Messages and configured instructions are sent to the active AI provider. Knowledge Base files are sent to the provider selected on the Knowledge Base page. OpenAI moderation and voice requests are sent only when those optional features are enabled.
-
Can I store chat logs in WordPress?
-
Yes. The plugin includes an option to save chat history in the WordPress database.
