Key Features
Powerful features available even in the free version
4 AI Providers
OpenAI GPT-5 series, Claude Opus 4.6 / Sonnet 4.5, Gemini 3 / 2.5, and OpenRouter with 100+ models. Choose the best AI for your needs and budget.
Web SearchNEW
When the knowledge base lacks information, AI automatically searches the web. Uses provider-native search with no additional API key required.
Vector RAGNEW
Hybrid search combining FULLTEXT (40%) and vector search (60%) for highly accurate contextual understanding and responses.
Grounded Answers OnlyNEW
When your content has no grounding for a question, the bot honestly says it doesn’t know instead of inventing a plausible-sounding answer. Stops hallucinations from misleading your visitors.
Usage Control — No Runaway BillsNEW
Per-visitor daily caps and rate limits are built into the free version. Abusive or bot traffic hits the cap instead of your API bill. Includes a usage dashboard.
Gutenberg Block
Fully integrated with the block editor. SSR (server-side rendering) support for easy chatbot placement within posts and pages.
MCP ServerNEW
Built-in MCP Server with 5 tools. Operate WordPress directly from Claude Desktop, Cursor, or VS Code. Pro adds product-search and analytics tools.
6 Free Themes
Default, Simple, Classic, Light, Minimal, and Flat themes included. Customize to match your site’s design.
Replies in 13 Languages
English, Japanese, Chinese, Korean, Spanish, French, German and more — 13 languages auto-detected from the visitor’s browser. Especially valuable for tourism, hospitality, and retail sites that can’t staff every language at the front desk.
Preset Question ButtonsNEW
Up to 10 one-tap chips under the welcome message — “Pricing”, “Hours”, “Staff perks” — so visitors don’t have to type. Canned reply mode bypasses the AI entirely for chosen chips: zero tokens, instant response, fully scripted wording. Pro adds hierarchical groups (parent ▸ children) for navigation-style bots.
Glossary (Proper Nouns)NEW
Register up to 50 product / service / brand names you don’t want the AI translating or rewording — no more “Rapls Works” coming back as “Rapls Workshop” in English replies. Optional per-language overrides (“EN: Staff Perks, ZH: 员工福利”) let you pin a specific translation per language.
Page Context AwarenessNEW
The AI automatically knows which page the visitor is looking at, so pronoun-only questions like “How much is this plan?” or “Summarize this article” resolve against the right page. Zero configuration — on by default.
Monthly Cost GuardNEW
Set a monthly API budget (USD): you get an admin warning at 80% and the AI calls pause automatically at 100% (resuming next month). Combined with per-visitor daily limits, surprise bills are structurally impossible. Model fallback keeps replies flowing on a lighter model when your main model hits its quota.
Unanswered Report & FAQ GeneratorNEW
Questions the bot couldn’t answer from your content are recorded and listed on the dashboard — add any of them to the knowledge base in one click. The AI can also cluster the last 30 days of real visitor questions into an FAQ draft and save it as a draft page. A built-in improvement loop that makes the bot smarter the more it’s used.
Visitor History DeletionNEW
An optional in-chat button lets each visitor permanently delete their own stored conversation from your server — GDPR-friendly by design. Ownership is verified server-side, so a visitor can only ever delete their own session.
Operations ToolkitNEW
Weekly summary email (conversations, cost, unanswered questions), a System Health panel (API key / cron / REST reachability checks), Google Analytics 4 events, WP-CLI commands, and 5 industry starter templates. Built for running the bot, not just installing it — all in the free version.

Frequently Asked Questions
Can I use just the free version?
Yes. The free version includes 4 AI providers, site learning, Vector RAG, Web Search, Knowledge Base, 6 themes, Gutenberg block, MCP Server, and more — all with no artificial limits. Pro Add-on adds analytics, lead capture, WooCommerce integration, LINE, and other advanced business features.
Is Pro a subscription?
No, it is a one-time purchase. Includes 1 year of updates and support. You can renew at $19/year, but the plugin continues to work even without renewal.
Where can I get API keys?
From each AI provider’s official site: OpenAI at platform.openai.com, Claude at console.anthropic.com, Gemini at aistudio.google.com, and OpenRouter at openrouter.ai.
Which AI model do you recommend?
For the best cost-performance balance, try GPT-4o-mini or Gemini 2.5 Flash. For top performance, Claude Opus 4.6 or GPT-5.2 are excellent choices.
What is MCP Server?
MCP (Model Context Protocol) Server lets AI tools like Claude Desktop, Cursor, and VS Code directly interact with your WordPress site. The free version provides 5 tools (get/list conversations, site info, knowledge search, send message), and Pro adds product search and analytics.
Can visitors run up my API bill?
No. The free version includes Usage Control: per-visitor daily caps and rate limits enforced server-side. Once a visitor hits the cap, the bot returns a canned message without calling the AI — so abusive or bot traffic stops at the cap, not at your credit card. A usage dashboard shows what is being consumed.
Is there a money-back guarantee on Pro?
Yes. Full refund within 14 days of purchase, no questions asked. Just send one email to info@raplsworks.com. See the Refund Policy for details.
How do I upgrade from Free to Pro?
Simply install the Pro Add-on plugin alongside the free version. All your settings and data are preserved. Available now at the Early Bird price of $29 (regular $59).
