Template notes

This template provides a high-performance, cost-optimized alternative to standard AI Agents for building RAG (Retrieval-Augmented Generation) chatbots.

Instead of relying on a single expensive model to decide every action, this workflow uses a modular "Routing & Specialized Steps" architecture.

It delivers results up to 50% faster and 3x more cost-efficiently by only involving heavy-duty models when deep internal knowledge is actually required.

By leveraging Lookio as the core RAG platform, you can connect your own documentation (PDFs, Docs, Webpages) to a chat interface without the complexity of managing vector databases or custom chunking strategies manually.
