Cognia — FAQ Chatbot

Cognia is an AI-powered FAQ chatbot designed to answer frequently asked questions using Natural Language Processing (NLP).

Instead of relying only on exact keyword matches, Cognia preprocesses the user's question and compares it with a collection of FAQ examples using TF-IDF vectorization and Cosine Similarity. This allows the chatbot to recognize different ways of asking the same question.
