Scenaloom - https://scenaloom.com

Scenaloom (https://scenaloom.com) is an AI screenwriting platform built around one draft. The AI script writer auto-formats to industry standard as you type - slug lines, action, dialogue, transitions - and the AI novel writer extends the same ask-first model to prose. FDX import and export keep Final Draft workflows intact, while live co-writing syncs your writers room in real time. The AI always asks before it edits, so you stay in creative control.
