Chatbase is an AI chatbot builder that allows users to create a customized chatbot for their website. Users can upload documents or add a link to their website to train the AI, which is based on ChatGPT. The chatbot can then be embedded as a widget on the website or accessed through the API. Users can give the chatbot a name, personality traits, and instructions on how to answer questions. They can also choose to embed an iframe or add a chat bubble to their website. The tool supports multiple file formats and can scrape websites for training data. It can answer questions in about 95 languages and offers options to make chatbots public or private. The AI model used is gpt-3.5-turbo by default, but users on specific plans can also use gpt-4. Chatbase integrates with popular tools like WordPress and Zapier. Potential applications include customer support, providing information about products or services, and engaging website visitors through interactive conversations.
