Can AI write a screenplay that reads like a screenplay?
The format is the easy part and the part most tools get wrong anyway. A screenplay is not prose with names in capitals. It is a strict document: INT. and EXT. scene headings, action in present tense, character cues, parentheticals used sparingly, dialogue that carries what the character will not say outright. BookFoundry routes screenplays to their own engine, separate from the one that writes books, because a scene is not a chapter and a beat is not a paragraph. It plans the structure first, then writes scene by scene against that plan. What comes back is a formatted script, not a story you then have to reformat. The harder part is subtext, and that is where you come in. The engine will give you a scene that works. Whether the line underneath the line is the one only you would write is still your job, and the script opens in a full editor so it can be.
