原文外掛簡介
Kethu Site Chat Assistant adds an AI assistant to your WordPress website. Visitors can ask questions, search public site content, perform safe calculations, and more through a lightweight chat interface.
This plugin uses the WordPress AI Client (wp_ai_client_prompt()). It does not call third-party AI provider hosts directly. Provider credentials are managed in Settings → Connectors.
Chat tools are registered through the WordPress Abilities API and executed only when the administrator enables them.
How it works
Visitor → Chat UI → WordPress REST API → Agent → WordPress AI Client → Connected provider → Abilities/tools → Final response
The AI does not have unrestricted access to WordPress. It can only use explicitly registered abilities that the administrator enables.

External services
Kethu Site Chat Assistant does not hard-code third-party AI endpoints. Requests are sent through the WordPress AI Client to whichever AI provider the site owner connects under Settings → Connectors.
If you connect OpenAI (or another provider) through Connectors:
User messages may be sent to that provider
Public website content may be sent when search tools are used
Retention and privacy are governed by that provider and by WordPress Connectors
Review the provider’s current terms and privacy policy before enabling AI
This plugin is not affiliated with or endorsed by OpenAI or other AI providers.
Privacy
Local WordPress retention
Conversation transcripts and conversation IDs are stored locally as WordPress transients for up to 24 hours.
Local transients are used for session isolation, conversation continuity, optional admin traces, and privacy export/erase.
Logging is optional and disabled by default. Optional logs stay in the WordPress database until cleared or the plugin is uninstalled.
The plugin does not sell user data.
The plugin does not phone home or send analytics to the plugin author.
Provider retention
User messages may be sent to the connected AI provider through the WordPress AI Client.
Deleting a local WordPress transient does not delete data already sent to a provider.
Configure your site privacy policy accordingly. Site owners remain responsible for privacy, consent, and legal compliance.
Security
Provider API keys are managed by WordPress Connectors, not stored by this plugin
REST endpoints use nonces and permission callbacks
Input validation, sanitization, and output escaping throughout
No arbitrary code execution
Retrieved website content is treated as untrusted data
Rate limiting helps prevent abuse
Troubleshooting
Confirm WordPress 7.0+ and that wp_ai_client_prompt() is available
Open Settings → Connectors and verify a provider is connected
Use Test AI Connection in Kethu Site Chat Assistant settings
Check that the agent is enabled
Confirm your hosting allows outbound HTTPS for the connected provider
