Overview
The nodes that bring documents into the flow and the one that produces files at the end.
Four nodes handle documents: two that bring content into the flow, one specialized in identifiers and one that produces files at the end.
What each node does
- File extractor: converts files received at the Input into plain text. The first node of almost every document flow.
- CPF extractor: finds, validates and extracts CPF and CNPJ numbers from an already processed text.
- Vector database: searches the workspace's Collections and returns the relevant passages. It is what enables RAG on the canvas.
- File generator: produces Markdown, DOCX or PDF from what the flow assembled.
The common chain
Document flows almost always follow the same order: the File extractor converts, a Logic node repeats per item, the LLM node interprets and the File generator closes.
The Vector database comes into flows that answer questions, not into the ones that process received files.
