What Makes Cossistant UniqueAI

Cossistant is an open-source, AI-native support infrastructure built for React and Next.js, designed to feel like a native part of your product rather than a separate widget. It features a self-learning knowledge base that crawls your docs and conversations, and an AI agent that asks for clarification when it doesn't know an answer, learning from human input.
