Build AI chatbots and automation agents for WordPress without coding. The built-in Chatbot Inspector module helps locate pages containing S2B AI Assistant shortcodes as well as chatbots and shortcode placements from popular third-party chatbot plugins. It can also detect popular widget-based chatbots across your website. Generate images using the OpenAI API. Core Modules 🤖 Chatbots Develop multiple AI chatbots with different styles and behaviors on different pages of your website. You can choose models from different AI API providers: OpenAI, Anthropic, Google Gemini, xAI, Deepseek. Personalize the appearance of each chatbot, including colors, styles and text, as well as its position, window size and behavior by configuring the model, instructions, temperature, token limits and other options. OpenAI Responses API and Knowledge Files S2B AI Assistant supports the OpenAI Responses API, allowing you to create chatbots that can use your own documents as a knowledge source. Upload product documentation, manuals, FAQs, company information or other supported files and let the chatbot search this knowledge when answering visitors’ questions. Each chatbot can have multiple knowledge files and its own independent knowledge base. S2B AI Assistant automatically manages the OpenAI Vector Store and File Search integration, so you do not need to create or configure vector stores manually. The Responses API integration also supports conversation history and model-specific options such as reasoning effort and response verbosity. You can use a regular Responses API chatbot without knowledge files, or add files when you want the chatbot to answer questions using your own content. This provides a modern alternative to the deprecated OpenAI Assistants API for document-based chatbots. Deep Customization feature This allows you to create a unique view for each chatbot using custom CSS rules. To do this, you need to find the ‘Deep customization’ section on the “Chatbots” tab, add the unique HTML ID of the closed and opened chatbot. You can then add CSS rules to each closed and open view of any chatbot. Separate CSS rules can be applied to different chatbots. Chatbot view modifications Use shortcode attributes to change how chatbots are displayed. [s2baia_chatbot view=embedded] — display chatbot directly inside the page without a modal window [s2baia_chatbot view_mode=fullscreen1] — open chatbot in fullscreen mode automatically after page load [s2baia_chatbot view_mode=fullscreen1 hideclose=1] — fullscreen chatbot without close button Available in S2B AI Assistant Pro Restrict chatbot access by user Link chatbot access to WooCommerce products Learn more about restricting chatbot access 🔍 AI Chatbot Inspector Detect chatbots from supported WordPress chatbot plugins and find where they are used across your website. Features Detect supported chatbot plugins Locate pages/posts where chatbot shortcodes are inserted Scan shortcode placements Inspect chatbot integrations across your website Chatbot Statistics Track chatbot engagement directly from your WordPress dashboard. S2B AI Assistant includes a built-in statistics engine that monitors both native S2B chatbots and supported third-party chatbot plugins, giving you a single place to measure chatbot performance. It includes: Chatbot Views Chatbot Opens Open Rate Today, This Week, This Month and All Time statistics Last activity timestamp Supported plugins AI Engine Tidio Buttonizer Chatway LiveChat S2B AI Assistant and more Available in S2B AI Assistant Pro Restrict access to chatbots from supported plugins by user Link third-party chatbot access to WooCommerce products Learn more about chatbot access control 📈 AI Tools Includes three AI-powered SEO agents: SEO Readability Rewrite (HTML only) – Improves clarity while preserving HTML structure. SEO Compare (Post vs URL) – Benchmarks your post/page against an external URL. SEO Compare URLs – Compares two external URLs and generates optimization suggestions. How It Works Each agent runs as a task: * Configure inputs * Content is fetched and analyzed * AI generates a structured SEO report * More detailed information can be found on this page Execution Modes Tasks run either: * Manually, or * In Background (WP-Cron queue) For background processing, WP-Cron must be enabled. If DISABLE_WP_CRON is set to true, queued tasks will not run but you can still run them manually. Available in S2B AI Assistant Pro * Multiple Tasks Per Agent find more 🎨 Image generation Image generation feature requires only API key. It is ready to use by default. You can configure generation options on the Image Generation tab. On the same tab you can generate and store new images using Dall-e-2 and Dall-e-3 models. 🧠 Content-Aware Chatbots (RAG) Build AI chatbots that answer questions using your website content. The plugin supports Retrieval-Augmented Generation (RAG) using external vector databases, Embedding API, and Chat Completion API. Upload selected posts or pages into a vector database to enable semantic search across your website content. When visitors ask questions, the chatbot retrieves relevant content and sends it together with the user query to the AI model. This allows you to: Build website-aware AI chatbots Reduce Chat Completion API costs Limit answers only to your website content Improve response relevance using semantic search Learn more: * Content-aware chatbot * RAG setup guide 🧩 Additional Features Conversation logging Token usage statistics Fullscreen chatbot mode Embedded chatbot view allows you to update models directly from OpenAI and independently choose the model to use from OpenAI API platform https://platform.openai.com/docs/models .
