AI Chatbot Hub — WordPress Plugin

One WordPress plugin to manage AI chatbots across Telegram, WhatsApp, Facebook Messenger, and your website — all powered by a single Gemini AI backend with a unified admin dashboard.

Why This Plugin

Managing multiple chatbots normally means:

  • Separate Node.js bots on different servers
  • Different dashboards for each platform
  • Duplicating the system prompt on every bot
  • No unified view of conversations

This plugin solves all of that. One install, one API key, one system prompt → all platforms live.

Features

  • 🌐 Website Widget — floating chat bubble, works on every page
  • ✈️ Telegram Bot — webhook-based, auto-registers webhook URL
  • 💬 WhatsApp — Twilio integration, TwiML response handling
  • 📘 Facebook Messenger — Meta Graph API v18.0
  • 🧠 Shared AI Engine — one Gemini API key, one system prompt
  • 💬 Unified Conversations — all chats stored in one DB table, viewable in one place
  • 📊 Platform Dashboard — live/offline status + message counts per platform
  • 🔌 Connection Testing — test each platform's credentials with one click
  • 🗑️ Conversation Management — view and clear any conversation from the dashboard
