Overview
The node palette, how nodes are grouped and how a node uses earlier results.
Nodes are the pieces of the canvas. Each one receives data, does one thing and hands a result to the next.
The palette groups them by purpose, and the following pages follow that split.
Reference what came before
Every node consumes what earlier nodes produced, through variables in the {{ node.field }} format.
{{ entrada.pergunta_usuario }}
{{ extrator_arquivos.contents }}
{{ llm.classificacao }}In fields that accept variables, the / key opens the selection menu, which avoids getting the node or field name wrong.
A node only reaches what is above it in the flow. Parallel branches don't see each other until an Aggregation node brings them together.
The groups
Input and output
The two required ends: the form the person fills in and the result they get.
LLM
Call an AI model with a prompt built from the flow.
Documents
Extract text from files, query Collections and generate documents.
Logic
Branch, repeat over lists and choose between results.
Integration
Talk to outside systems through HTTP, email or an installed integration.
Code
Run Python or Node.js for what no ready-made node covers.
