The reading-level slider
Drag from the expert source down to plain language. The Flesch–Kincaid score updates live, the citation follows every version, and the meaning-drift check flags any point where simplification changed a fact that had to survive. Pick a subject, choose the second sample in each, and slide to the simplest level to see a real drift flag.
