AI Chatbot & Semantic Search: ChatGPT Answers From Your Content

Answers your visitors can trust, drawn only from your own content. SmartSearchWP turns your WordPress site into an AI assistant that replies from YOUR posts and pages, grounded in your data instead of generic ChatGPT answers. It pairs an AI chatbot with a semantic search engine (RAG) that retrieves the right passages from your content before it answers. It runs on your own site, with your own OpenAI key.

Premium: unlock all 10 premium add-ons (WooCommerce, PDF, custom post types & ACF, lead capture, analytics, usage control, prompt override, and more) for €49.99/year. Get SmartSearchWP Premium »

Whether you run an eCommerce store, corporate site, blog, or documentation platform, SmartSearchWP improves engagement, reduces support workload, and enhances content discovery.

What makes SmartSearchWP different

Most AI chatbot plugins simply forward your visitors to OpenAI. SmartSearchWP is built around three ideas:

• Grounded in YOUR content. Answers are retrieved from your own posts and pages using embeddings (RAG), so replies stay on topic and reflect what you actually published, not the open web.
• Self-hosted, your key. The plugin runs on your WordPress install and calls OpenAI with your own API key. Your content and your keys stay under your control, which helps with GDPR compliance.
• Modular, not bloated. A complete free core, extended by dedicated premium add-ons you install only if you need them.

No competing plugin combines all three at once: grounded answers from your own content, running on your own site, with your own key.

What you get

• Fewer repetitive support requests: visitors get instant, content-based answers.
• Better content discovery: semantic search surfaces the right page instead of keyword guesses.
• Answers you can stand behind: responses are drawn from your published content, not invented.
• Full ownership: your site, your OpenAI key, your data.

Core Features (free)

AI Chatbot Integration

Connect your website to OpenAI’s ChatGPT models to provide dynamic, contextual answers based on your own content.

All available ChatGPT models are presented in the plugin settings depending on your API key and OpenAI account. Supported models include Chat models (gpt-4o, gpt-4o-mini, gpt-4.1, etc.), Reasoning models (gpt-5, o3, o4-mini, etc.), and legacy options, each with recommendations, estimated cost levels, and suitability guidance for chatbot use.

Semantic Search Engine

Improve content discovery with AI-driven semantic search instead of simple keyword matching.

Contextual Content Indexing

Index your posts and pages so the chatbot answers from your own content. (Indexing custom post types and ACF fields is available with the premium Custom Type Manager add-on.)

Modular Architecture

Extend functionality through dedicated addons without bloating your core installation.

No request or usage cap is reserved to a paid tier: the free core is complete, and you bring your own OpenAI key.

Premium Add-ons

A premium license unlocks the add-ons that extend what the assistant can read and do:

• WooCommerce Integration (premium addon): use your products, with SKU and price, as a content source.
• PDF (premium addon): add the content of your media-library PDFs to the answers.
• Custom Type Manager (premium addon): index custom post types and ACF fields (the free core indexes posts and pages).
• Prompt Override (premium addon): replace the system prompt to control tone and scope.
• Usage Control (premium addon): restrict access by role, page, device, schedule, or question budget.
• RAG Auto Sync (premium addon): automatically re-index new content (uses your OpenAI key).
• Lead Capture (premium addon): collect visitor emails in-chat with a GDPR form and CSV export.
• Analytics & Insights (premium addon): a KPI dashboard over your chat logs (top questions, charts, CSV, weekly email).
• RAG Debugger (premium addon): test questions and inspect the retrieved contexts.
• Customization (premium addon): adjust the chatbot appearance (colors, position).

Who it’s for

• Site owners, agencies, and developers who want answers grounded in their own content.
• Teams that prefer a self-hosted tool using their own OpenAI account rather than a SaaS black box.
• eCommerce, corporate, blog, and documentation sites that want to reduce support load and improve discovery.

Who it’s not for

• Anyone who does not want to use their own OpenAI API key (the plugin needs one to answer).
• Sites looking for a fully managed, hosted chatbot with no setup: SmartSearchWP runs on your server.
• Live human-agent chat: SmartSearchWP answers from your content, it is not a live-chat helpdesk.

Performance & Safety

SmartSearchWP follows WordPress development standards and keeps a clean separation between core functionality and extensions.

• Lightweight architecture
• API-based processing via OpenAI
• No unnecessary front-end bloat
• Full administrative control
• Easy activation and deactivation

SmartSearchWP does not store unnecessary data and allows you to manage and limit API usage efficiently.

Use Cases

• eCommerce stores providing instant product assistance
• Corporate websites reducing support requests
• Blogs with large content libraries improving discoverability
• Technical documentation sites offering intelligent Q&A
• Agencies deploying scalable AI solutions for clients

The chatbot uses OpenAI as a third-party service to generate its answers. You can find more information about OpenAI here and consult their privacy policy.

Optional usage statistics (off by default): if an administrator enables the Usage statistics setting, the plugin may send plugin version, license type (free/premium), counts for five admin-interface events, and a hashed site identifier (SHA-256, not the raw domain) to smartsearchwp.com. No email, IP, API key, chat log, page content, or visitor data is sent. Front-end visitors are never tracked. Unchecking the setting stops sending data and discards the local queue.
