One shared brief
Every tool receives the same topic, learning goal, source facts, and one-minute target. We do not repair weak visuals after generation.
Visuals must teach
A high score requires visuals that explain the idea. Text that repeats the narration is not enough. Reviewers do not see the tool name.
Overall first, details second
The Explainer Index combines 45% visual explanation, 30% speed, and 25% cost. Separate tabs show each measure.
Workflow labels matter
One-shot, scene-by-scene, framework, and manual workflows stay labeled. We do not present manual work as automation.
Changes stay visible
Method changes start a new comparison window. Errors go in the public corrections log.
