Chatbase is an AI tool that allows users to create a custom chatbot using their existing knowledge base. The AI chatbot can be added directly onto a website or could be interacted with through Chatbase's API.

The tool is primarily used for customer support, lead generation, and user engagement on a site. It employs Generative Pretrained Transformers (GPT) models, with options that include GPT-3.5-turbo and GPT-4, to train the chatbot based on the data sources provided by the users which can include multiple data sources and can fetch data through web crawling.

The chatbot once created can be customized visually and behaviorally to align with the brand aesthetics and requirements. The tool additionally supports retraining capabilities to enable the chatbot to continually adapt and improve its results based on the latest data.

For more accuracy, features like 'Revise Answers' and 'Confidence Scores' are included to ensure the responses provided by the bot are correct. Chatbase also facilitates collecting and handling leads while delivering personalized customer experiences.

Its advanced analytics feature provides insights into the chatbot-customer interactions, useful in improving performance and understanding customer needs better.

The tool offers integration options with other popular tools like Slack, WhatsApp, Zapier and supports over 80+ languages allowing interaction with customers in their native language.

Chatbase respects privacy and security by hosting data on secure servers with robust encryption and access control. Chatbase can be utilized for diverse use-cases such as customer support, lead generation, user engagement, and on multiple platforms.
