Hook & Thumbnail Factory

Name: NodeTool
Author: NodeTool

One video topic in, a full thumbnail pack out: scroll-stopping hook lines plus a color-graded, ready-to-post thumbnail for each. The differentiator is the fan-out — one hook stream drives a whole gallery of matching images in a single run. Uses fal-ai/flux/schnell (cheap, fast).
