How a scene for the screen differs from a scene in prose
The decisive difference between a screenplay and a novel is the camera. A novel can write a character's thoughts; a screenplay cannot, because thoughts do not photograph. A script contains only what an actor can perform: action, dialogue, silence. "He was sad" cannot appear in a script; "JUNHO picks up his chopsticks, puts them down" can. This tool writes by that rule. It takes a scene description and returns one scene where the action lines contain only what is seen and heard, and the emotion lives in the gap between what people say and what they do.
The two supported formats differ in layout. Standard US format uses a slugline (INT. DINER – DAWN), action in paragraphs, character names in capitals, and centered dialogue. Korean TV drama format numbers scenes (S#1. Diner – Dawn), writes action as plain prose, and puts the character name and dialogue on one line, with (E) for off-screen voice, (N) for narration, and (F) for filtered voice such as a phone. Pick the format with the chip; the default is US format on the English page.
A good scene has three things: a character who wants something, someone or something in the way, and the thing that is not said. If you write "the junior is certain the suspect is innocent and cannot say so," the dialogue will go around the subject instead of through it. If you only describe the situation, the characters will tend to announce their feelings, and lines like that are hard to act. Spend one sentence of your input on what each character is hiding and the scene improves more than any other change.
The output is one scene of one to two pages, and the free version does not continue past it. This is not a tool for generating a whole script; it is for finding how a scene should open and where it should cut. To chain scenes and keep each character's voice consistent, create a screenplay project in the Studio, which also converts prose to script and script to prose.
The free tool runs three times a day without an account, and nothing you enter is used for training. If a generated scene loses its formatting when pasted, or you have a script written as loose notes, the drama script formatter on this site restores scene numbers and alignment without any AI, entirely in your browser.
