AI Engine review

AI Engine is the most complete AI plugin in the WordPress directory, and its chatbot runs inside your own site rather than as a third-party widget. You pick the model from OpenAI, Anthropic, Google, Mistral and others, and Meow Apps adds no markup because you pay the provider directly. Chatbots come with five themes, a theme editor, popup, inline or fullscreen layouts, realtime voice conversations, file uploads and conversation memory, plus IP banning, word filters and GDPR tools. The plugin also turns the site into an MCP server with more than 140 tools, so Claude or ChatGPT can write posts and fill SEO fields with one-click undo. Pro starts at $59 a year for one site and is where the chatbot learns your own content, along with AI forms and voice. The trade-off is setup: you manage API keys and model choice yourself, and there is no live chat inbox for a human to take over.
