Screenplay is its own project type in Alistair: a real industry-format editor, not a reskinned manuscript. No slugline punctuation to memorize. Every element is a deliberate click.
From New Project, choose Screenplay instead of Manuscript. This isn't a cosmetic switch. It swaps in a purpose-built element-type editor, Courier 12pt page geometry, and a dedicated compiler built for scripts, not prose.
Your project home works exactly the way it does for a novel: word count, scene count, daily goal, and a writing streak, just tracking Sequences instead of chapters. Characters, World Building, and Story Elements all carry over too. Screenplay projects use the same cast-and-world tools as a manuscript.
Click Start Writing to create your first sequence. Instead of typing formatting conventions, a toolbar sits above the page with one button per element: Scene, Action, Character, Paren., Dialogue, Trans. Click one to set what the current line is, and Alistair handles the margins and capitalization.
A scene heading isn't one line you type from scratch. It's three small fields: INT./EXT., a Location you type freely, and a Time of Day you pick from a list. Alistair composes them into the correctly punctuated, all-caps slugline automatically.
Write the action line, click Character, and type a name. Alistair autocompletes from characters already used in the project. Then write the dialogue underneath. Each element type gets its own correct indentation automatically.
When you're ready to share a script or move it into another tool, Export offers a plain-text Fountain file or industry-standard Final Draft (FDX), both readable by virtually every other screenwriting app.
