Core Features

Your AI chatbot includes everything you need for intelligent customer engagement:

✅ Agentic AI Actions System
Your AI doesn’t just answer questions—it takes action. Detects user intent and triggers real actions: send emails, fire Slack notifications. Conversationally collects unlimited custom parameters including smart recommendations (vector-searched WordPress CPTs—products, services, any custom post type) and includes them in action execution. No static forms needed—just natural conversation that gets things done.

✅ Live Agent Handoff via Slack
Seamless AI-to-human transition when needed. When your AI can’t help, conversations transfer directly to your team via Slack channel with full context. Human agents see entire chat history and can respond in real-time. WhatsApp and Telegram support coming soon.

✅ Quick 3-Step AI Chatbot Setup
Guided wizard launches after activation. Connect your AI provider, configure personality, add knowledge sources, and customize appearance—live in under 5 minutes.

✅ Advanced AI Chatbot RAG Technology
Train on unlimited WordPress content using Retrieval-Augmented Generation. Supports pages, posts, custom post types, PDFs, text files, rich text input, and Q&A entries. Intelligent intent recognition retrieves the most relevant knowledge for accurate responses.

✅ Chat Discussions Dashboard
Complete conversation management with detailed insights. View all transcripts, see which knowledge sources AI used, add missing Q&A entries directly, and track user information including guest/logged-in status and IP addresses.

✅ Cost-Optimized AI Usage
Smart token management minimizes API charges. Intelligent request optimization ensures you pay only for what you need. Configure rate limits to control expenses.

✅ Customizable Chat Experience
Unlimited widgets including Message Starters, Message Prompts, Chat History, Links, and custom announcements. Fully customizable greetings with emoji support.

✅ Flexible Vector Storage
Choose local WordPress database (free, unlimited) or Pinecone for enterprise-scale knowledge bases. Vector embeddings enable fast, contextually relevant retrieval.

✅ Complete Customization
Customize colors, chatbot icon, AI avatar, chat box size, themes (light/dark/system), positioning, emojis, and greeting messages. Adapts seamlessly to all devices.

✅ Multi-Language Support
Conversations in multiple languages with RTL compatibility. The AI chatbot responds in your visitors’ language.

All conversation data stored locally on your WordPress site. You control data retention, export, and deletion policies.
