dr.aft
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.

CanonDraft
CanonDraft is browser-based screenwriting software for developing film and television scripts. Its editor formats scenes, action, dialogue and transitions, while the connected desk organizes script scenes as index cards on act-based cork boards with characters, locations and research clippings. The Notebook tracks written scenes beside an idea beat board; outlines can use three-act, Save the Cat, hero’s journey, film-with-interval or TV-episode structures. A project bible collects cast and places, and research clippings retain cited sources. An optional AI writers’ room discusses the script and maps scene-by-scene tension; it does not change pages unless accepted. Users can import Fountain or plain text and export scripts as PDF, Fountain or Final Draft files; outlines can be exported as PDF or Word. Free accounts support up to three scripts; Pro adds unlimited scripts and monthly AI image allowances.
