AI Screenwriting Software for Pros

Build screenwriting software that helps film and TV writers outline, draft and revise without sounding like generic AI.

In plain English

Film and TV writers can outline, draft, and revise in Laper, the software Zhao Chunxiang runs from Hong Kong. It is built around scenes, spoken lines, and a simple map of the story's main moments, and the aim is to keep the writer's own voice. Writers pay for each person using it, alone at first and later as a group writing together, because the pages still need to fit file types film people already use. The AI does a large share of the draft help and the billing. Zhao still does a fair amount, tuning how the writing feels, supporting those file types, and spending time with screenwriter groups.
