Chatbase

Chatbase is a platform for building AI customer support agents — chatbots that answer straight from your own materials. Behind it is a startup of the same name that grew from a small side project into a global service used by thousands of businesses, from e-shops to SaaS. It suits anyone who keeps getting the same questions and wants a bot that genuinely knows their product.

It works in three steps: you upload your sources — a website address, PDFs, documents, or Notion — and Chatbase builds a knowledge base from them. You then set the agent's instructions, tone, and the look of the chat window, test it with trial questions, and finally place it on your site with a single snippet of code. From that moment it answers visitors on its own, drawing only on what you gave it.
