What Kaia is

Kaia is an open-source platform for adding a customizable AI chatbot to a website with a code snippet. Its GPT-4o assistant streams responses and is designed to answer questions, qualify leads, book appointments, and support sales at any hour. A dashboard manages unlimited branded chatbots across multiple domains, with a separate icon and color settings for each domain. It also displays conversation statistics, captured leads, and bookings.

Beyond chat, Kaia provides slot-based appointment booking, email campaigns for segmented customer lists, and product showcases inside the chat window. Agents can take over live conversations through Pusher. The listed stack includes OpenAI, Clerk, Stripe, Pusher, Uploadcare, and Nodemailer. Kaia is MIT-licensed and its README identifies Andrea D'Ambrosio as the maker. It is Docker-ready and Vercel-ready, and can run anywhere Node.js runs. The quick start requires Node.js 18.17 or later and PostgreSQL 15 or later, with Docker Compose offered for database setup. The README names Stripe subscription tiers Standard, Plus, and Ultimate, but does not state their prices. WhatsApp, Telegram, multilingual chat, rate limiting, and analytics export appear as roadmap items.
