Architectural & Operational Deep Dives
1. Rule-Based Bots vs Autonomous RAG Agents
Crisp provides a reliable, clean shared inbox, but its native chatbot features rely primarily on decision-tree routing and keyword heuristics. When customers ask complex, nuanced questions spanning multiple documentation pages, rule-based systems break down. Chatty uses semantic vector search with cosine thresholding across your full documentation, generating accurate answers with clickable article source citations.
