Paste a draft, then inspect sentence length, shape, sound, and variation across the piece.
Colors are based on word count: 0–10 (short), 11–20 (medium), 21+ (long).
Click a sentence (in the body, shape view, or waveform). Stats use a window centered on that point. Variety index is higher when sentence lengths in the window are more varied (dynamic), lower when they’re similar (more monotone). Syllables per word trends: ~1.0–1.3 faster / punchier, ~1.4–1.7 middle, 1.8+ denser / slower.
