About flowgram.ai

FlowGram is a composable, visual, easy-to-integrate, and extensible workflow development framework & toolkit. Our goal is to help developers build AI workflow platforms faster and simpler. FlowGram comes with a suite of built-in tools for workflow development: flow canvas, node configuration form, variable scope chain, and ready-to-use materials (LLM, Condition, Code Editor etc). It’s not a ready-made workflow platform; it’s the framework and toolkit to build yours.

In this demo, we iterate through a list of cities, fetch real-time weather via HTTP, parse temperatures with a Code node, generate outfit suggestions with an LLM, gate by a Condition, aggregate results across the loop, and finally use an Advisor LLM to pick the most comfortable city before sending the result to the End node.
