Limb AI Chatbot is a WordPress plugin that adds a bring-your-own-API-key AI chatbot to any WordPress or WooCommerce site. Site owners connect an OpenAI, Claude (Anthropic), Google Gemini, DeepSeek, or Grok API key, then train the assistant on their own content through a knowledge base and retrieval-augmented generation (RAG) pipeline that syncs WordPress posts, PDFs, URLs, and sitemaps. The chatbot answers pre-sale and support questions around the clock, and on WooCommerce stores it can act as a shopping assistant that searches products, tracks orders, and shows product recommendation cards. Widgets such as greeting overlays, lead-capture forms, promotional banners, and conversational forms are configurable through a styling editor with live preview. Pro plans add a live-agent handoff inbox (a mobile-friendly PWA with AI-suggested replies) so human staff can take over escalated conversations, plus Gutenberg block support for embedding chat UI directly into page layouts. The plugin is built by limb.dev and integrates with WooCommerce, Advanced Custom Fields, Elementor, Slack, Telegram, Calendly, Pinecone, and Qdrant.

Pros & Cons
Pros
Bring-your-own-API-key model lets site owners choose and control costs across OpenAI, Claude, Gemini, DeepSeek, or Grok rather than being locked into one provider
Deep WordPress/WooCommerce integration, including a shopping assistant, product search, and order tracking built specifically for WooCommerce stores
Knowledge base can sync directly from WordPress posts, PDFs, URLs, and sitemaps, so training the bot on existing site content is straightforward
Pricing is a one-time lifetime option as well as annual/monthly subscriptions, giving buyers flexibility, plus a 14-day money-back guarantee
Free tier includes core AI-provider connections and a basic knowledge base, so smaller sites can try it without paying
Cons
Advanced features like the WooCommerce shopping assistant, live-agent handoff, product recommendation cards, and abandoned-cart widgets are gated behind paid Pro tiers
Requires users to bring and manage their own AI provider API key (and its usage costs), rather than offering an all-inclusive managed AI backend
Site-count-based pricing (1 / 5 / 20 sites) means larger multi-site portfolios need the higher tiers
Gutenberg block support is listed as 'coming soon,' so drag-and-drop chat block placement is not yet fully available
