Greenlight screenshot

Greenlight orchestrates screenplay workflows — import Final Draft, Fountain, FadeIn, or PDF; export to multiple formats; validate schemas; optionally encrypt content. Wraps screenjson-cli with a YAML task system. Compose convert, export, validate, encrypt, decrypt, and zip without code. Built for screenwriting platforms, film studios, and script management at scale.
