Curio AI Chat: A Grounded, Privacy-First WordPress Chat Assistant

Overview

Curio AI Chat is an open-source WordPress plugin designed to solve a critical flaw in most AI chat widgets: the tendency to hallucinate or invent facts when they cannot answer a question. Unlike standard AI plugins that might confidently fabricate prices, dates, or phone numbers, Curio is built to answer only from a knowledge base you control. If a question is not covered, the plugin explicitly states it does not know and offers to hand the visitor to you, rather than guessing.

Benefits

Curio offers several key advantages for website owners who want reliable and secure customer support.

• No Hallucinations:The plugin uses a strict retrieval-first architecture. It searches your site for answers before asking an AI model. If no match is found, no request is sent to an AI, and the plugin simply states it does not know the answer.
• Accurate Information:Answers are always backed by citations linking to the source pages on your site. This allows visitors to verify the information easily.
• Cost Control:Curio includes built-in limits to prevent unexpected charges. It features per-visitor rate limiting, a configurable monthly ceiling on API calls, and answer caching for repeat questions.
• Privacy First:The plugin prioritizes user privacy. It does not store IP addresses, uses no cookies for conversations, and encrypts API keys at rest. Conversations are stored only in the user's browser tab and are deleted when the tab closes.
• Flexible AI Integration:You can connect your own AI provider, such as Anthropic, OpenAI, or Google. You paste your own API key, and the plugin pays the provider directly. No data is resold or routed through the developer.
• Demo Mode:The plugin ships in demo mode by default. It answers from your knowledge base without needing an API key, allowing you to test functionality without spending money.

Use Cases

Curio AI Chat is ideal for WordPress site owners who need a trustworthy chat assistant that aligns with their brand and content.

• E-commerce Stores:The plugin can read WooCommerce product data, including descriptions, prices, SKUs, and stock status. This makes it perfect for answering customer questions about specific products and availability.
• Service Businesses:Companies with specific policies, such as opening hours, cancellation rules, or pricing policies, can add hand-written answers. These entries are weighted higher than indexed text to ensure accuracy.
• Content-Rich Sites:Bloggers and publishers can index their existing pages and posts. The plugin splits content into passages for granular matching, ensuring answers are relevant to the specific content on the site.
• Privacy-Conscious Organizations:Sites that must comply with GDPR or have strict data security policies will appreciate that Curio does not store user identities or site credentials and minimizes data transfer to external AI providers.
• Lead Generation:When the assistant cannot answer a question, a hand-off button appears. This directs the visitor to a contact page, email, or booking link, turning a dead end into a lead generation opportunity.

Pricing

Curio AI Chat is an open-source plugin available on WordPress.org. The core software is free to install and activate. However, using the AI features requires an API key from a provider like OpenAI or Anthropic, and you pay those providers directly for the usage. The plugin includes a demo mode that costs nothing and allows you to test the chatbot without connecting an API key.

Vibes

As an open-source tool, Curio has received positive attention from the WordPress community for its focus on reliability and privacy. Users appreciate that it solves the common problem of AI chatbots making things up. The ability to test the plugin in demo mode before paying for an API key has been highlighted as a major benefit for developers who want to avoid unexpected costs. The plugin's commitment to not storing IP addresses and its transparent data handling have made it a trusted choice for sites concerned about user privacy.

Additional Information

Curio AI Chat is open-source software, which means its code is publicly available for review and modification. It supports various AI providers including Anthropic, OpenAI, and Google Gemini. The plugin also supports custom providers for developers who want to use self-hosted models. It includes full WP-CLI support for command-line management, making it easy to provision and manage on staging or production environments.
