Why per-tool prompts: Lovable needs component-level instructions, Bolt prefers a single spec, Cursor wants file structure, Codex a task brief that ends in checks. Each tab is written for its tool: same design, 5 dialects.

What this prompt builds

A diagram notebook landing on cream paper: scroll scrubs a fountain pen finishing its ink line while a corner sketch draws itself in step with the film. Below it every illustration inks itself in as it enters view, margin notes ring a real product screen, and Nib, a small ink mascot, walks a drawn path that links each section down to a per-editor price you set yourself.

Paste it into Lovable, Bolt, Cursor, Claude or Codex, then change the copy, colours and footage to make it yours. Scroll the live demo to see exactly what it builds.
