Layerworks AI Chatbot
Layerworks AI Chatbot helps WordPress site owners answer visitor questions before they become manual inquiries. It is designed for small businesses, shops, local organizations, agencies, and service websites that want a practical AI chatbot based on information they have reviewed. The plugin creates chatbot knowledge from selected published pages, lets an administrator review and edit that knowledge, and can collect supplemental knowledge from published posts and custom post types. Visitors can ask questions in the chat widget, and site administrators can review inquiries, chat logs, CSV exports, retention settings, and basic usage insights from the WordPress admin area. Developed by LAYERWORKS Co., Ltd. This plugin does not automatically train or fine-tune an AI model from conversations. Administrators review site content and inquiry records manually. Basic usage counts are shown from saved logs. Use it to: Add a floating AI chat widget to a WordPress site Answer common visitor questions from reviewed site knowledge Collect inquiries when visitors still need human follow-up Review chat logs and export them as CSV Keep product names, service names, and brand terms from being changed by AI replies Start with English plugin text and bundled Japanese translations Main free features: Chat widget for the front end Safe readable formatting for chatbot replies, including lists, bold text, and links OpenAI Responses API integration Separate OpenAI model settings for chat responses and knowledge design Basic knowledge setup from selected published pages with editable review flow Editable fixed knowledge sections Background supplemental knowledge collection from published posts and custom post types Protected terms to keep product names, service names, and brand names unchanged Widget position and margin adjustment to avoid overlap with fixed page buttons Widget motion effect setting Bundled chatbot icon selection Response style selection Device visibility controls for desktop, tablet, and mobile Excluded page ID setting to hide the widget on specific posts, pages, and custom posts Inquiry form and inquiry management screen Inquiry email notifications with configurable recipient, subject, body, and test sending Chat log review, search, deletion, and CSV export Chat log storage retention and cleanup settings Basic usage insights from saved chat logs Rate limit and safety settings visibility Automatic multilingual response handling English source strings with bundled Japanese translation files The chatbot, knowledge management, inquiry form, inquiry management, inquiry email notifications, chat log review, CSV export, log storage settings, basic usage insights, and response style features are included in this free plugin. External Services This plugin connects to the OpenAI API, using the API key configured by the site administrator, to generate chatbot responses and to help administrators create editable knowledge drafts. Service: OpenAI API Endpoint used: https://api.openai.com/v1/responses The plugin does not send data to OpenAI until an administrator configures an OpenAI API key and uses a feature that requires AI processing, such as a visitor chat response, the admin test chat, the OpenAI connection test, or basic knowledge creation. When OpenAI settings are configured and a visitor sends a message, the plugin may send the following information to OpenAI: The visitor’s message Recent conversation history Basic knowledge configured by the site administrator Supplemental knowledge collected from published posts and custom post types Protected terms configured by the site administrator The current page URL, when it is used as part of the chat context When an administrator creates basic knowledge, the plugin may also send selected published page content, current knowledge sections, protected terms, and the site name and URL to OpenAI. When an administrator uses the test chat, the test message and the same knowledge context may be sent to OpenAI. Test chat conversations are not stored as chat logs by this plugin. The OpenAI API key is stored in the WordPress database and is not exposed to visitors. Saved API keys are not printed back into the settings field. The plugin should not automatically include private administrator-only information, such as the WordPress admin email address, in generated knowledge. OpenAI terms and privacy information: https://openai.com/policies/terms-of-use/ https://openai.com/policies/privacy-policy/ Chatbot Response Languages The chatbot response language is not limited to Japanese and English. The chatbot detects the visitor’s language and tries to answer in the same language where possible. Important business, pricing, contract, disclaimer, and contact information should be based on administrator-configured knowledge and should not be guessed. Plugin Interface Languages The plugin interface uses English source strings and includes bundled Japanese translation files so that both English-speaking and Japanese site administrators can use it.
