BALLOON CATEGORIES FOR EVERY SCENE
Choose from five distinct comic bubble categories built to suit classic graphic storytelling:

Standard Speech: Clean elliptical contours paired with smooth, natural tail geometry.

Jagged Scream: Explosive starburst and radial edges designed for alarms, combat, and yells.

Narrative Caption Box: Rectangular editorial boxes featuring classic double-border styling for scene descriptions and time jumps.

INTELLIGENT AUTO-FITTING BUBBLE GEOMETRY
Say goodbye to awkward dialogue margins. As you type your script, LetteringBalloon dynamically calculates the required text volume and automatically expands the elliptical balloon to maintain balanced comic aspect ratios. Your dialogue remains comfortably framed with balanced breathing room on every side.
