You (the site owner) must supply the API keys. No keys are bundled and no traffic is proxied through a vendor server controlled by this plugin author. 1. OpenAI Used for: chat completions / responses, embeddings (context indexing), moderation (safety checks). Endpoints used (HTTPS): * https://api.openai.com/v1/chat/completions (legacy Chat Completions) * https://api.openai.com/v1/responses (Responses API – new unified endpoint if configured) * https://api.openai.com/v1/embeddings (document/post/PDF embedding + wizard indexing) * https://api.openai.com/v1/moderations (content moderation) Data Sent: * User prompt text (per message) and limited conversation history (trimmed for token control) * System / policy instructions (security + privacy policy + bot instructions) * Optional retrieved context snippets (only the selected top‑N chunks or page excerpt – never the full original document) * Embedding requests: raw chunk text produced from your site’s content or uploaded PDFs * Moderation: only the user prompt text (not the entire history) Data Retention (Your Server): * Conversation log rows (if logging enabled) including user prompt, model reply, timestamps, bot slug, session id, optional user id. IP (binary) only stored when per‑IP limits are turned on. Disable logging to stop storing new rows. * Embeddings table stores numeric vectors generated from your content (not reversible plaintext) plus the original chunk text for retrieval. Recommendations: * Update your privacy policy to disclose sending user prompts and limited site content to OpenAI for processing. * Disable logging or periodically purge if you process personal data. Legal / Docs: * Terms: https://openai.com/policies/terms-of-use * Privacy: https://openai.com/policies/privacy-policy * Usage Policies: https://openai.com/policies/usage-policies Opt‑Out / Control: * Remove the OpenAI API key in Settings to stop all OpenAI calls (bots will refuse to answer). * Disable conversation logging. * Limit context ingestion to non‑sensitive pages. 2. Anthropic (Claude) Used for: alternative chat completions via Claude models (messages API) when a bot provider is set to Anthropic/Claude. Endpoint used (HTTPS): * https://api.anthropic.com/v1/messages Data Sent: * A rewritten message array: system instructions + user prompt + condensed prior turns (trimmed) + optional retrieved context snippets. * Model identifier, max tokens / temperature style parameters. Headers: * x-api-key (your key) and anthropic-version (currently 2023-06-01 set in code). Retention (Your Server): * Same as OpenAI notes for conversation logging (the provider choice does not change local storage schema). Legal / Docs: * Terms: https://www.anthropic.com/legal/terms-of-service * Privacy: https://www.anthropic.com/legal/privacy * Usage Policy: https://www.anthropic.com/legal/aup Opt‑Out / Control: * Leave the Claude API key blank; those bots will fallback/refuse if provider requires it. * Switch provider per bot back to OpenAI. 3. Pinecone (Optional Remote Vector Store) Only used if you explicitly create a Context with remote type “Pinecone”. Local context mode (default) never contacts Pinecone. Endpoint Pattern: * Region/index specific HTTPS endpoints you enter (example placeholder: https://controller.pinecone.io and index query/upsert endpoints under *.pinecone.io). The plugin validates host against an allowlist containing pinecone.io (filter extendable). Used For: * Upserting embeddings (during context indexing / syncing) * Querying similar vectors when answering a question in that context. Data Sent: * Vectors (embedding arrays) and associated metadata (post/page IDs, titles, short chunk text) for upsert. * Query: the embedding vector of the user question + top‑K request. Retention: * Stored inside your Pinecone project (not on this plugin server). Local DB still keeps minimal reference metadata if you mix modes. Legal / Docs: * Terms: https://www.pinecone.io/terms/ * Privacy: https://www.pinecone.io/privacy/ * Security: https://www.pinecone.io/security/ Opt‑Out / Control: * Do not configure a remote Pinecone context; use local mode or page mode instead. * Delete the remote context to stop future upserts/queries. 4. Google Gemini (Optional AI Provider) Used for: alternative chat completions via Google Gemini models when a bot provider is set to Google/Gemini. Endpoint used (HTTPS): * https://generativelanguage.googleapis.com/v1beta/models/{model}:generateContent Data Sent: * System instructions + user prompt + condensed prior turns (trimmed) + optional retrieved context snippets. * Model identifier and generation configuration parameters. Headers: * API key passed as URL parameter (key=). Retention (Your Server): * Same as OpenAI notes for conversation logging. Legal / Docs: * Terms: https://ai.google.dev/gemini-api/terms * Privacy: https://policies.google.com/privacy * Usage Policy: https://ai.google.dev/gemini-api/terms Opt‑Out / Control: * Leave the Gemini API key blank; those bots will fallback/refuse if provider requires it. * Switch provider per bot to OpenAI or Claude. 5. Freemius SDK (Licensing & Analytics) This plugin uses the Freemius SDK for license activation, update delivery, and anonymous usage analytics (opt-in). Endpoints used (HTTPS): * https://api.freemius.com (license checks, updates, analytics) Data Sent (if opted in): * Site URL, WordPress version, PHP version, plugin version, and admin email. * No visitor/chat data is ever sent to Freemius. Legal / Docs: * Terms: https://freemius.com/terms/ * Privacy: https://freemius.com/privacy/ Opt‑Out / Control: * During activation, choose “Skip” to opt out of anonymous analytics. * License-related API calls are required only for premium features. 6.

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). Premium add-ons are available with a license at €49.99/year: Get SmartSearchWP Premium » 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.
