dr.aft is an AI-powered screenwriting editor purpose-built for writers who want clean, production-ready scripts without worrying about formatting. It natively supports the .fountain screenplay format, ensuring your script structure (slug lines, dialogue blocks, scene spacing, page breaks) remains intact while you write. Inline, context-aware AI suggestions help you craft scenes, dialogue, and narrative flow, all within the editing interface, without ever breaking format rules. It also offers “custom style steering” so you can subtly guide the AI’s tone and structure according to your preferred style, plus a distraction-free composition mode to help you focus on writing. For those who prefer using their own AI models, dr.aft supports a “Bring Your Own Key (BYOK)” option, letting you connect your own API key for flexible AI integration under your control. The result is a streamlined workflow that blends human creativity with AI assistance.
