The AI-Powered Screenplay Editor for macOS
Inkwell is a screenwriting app with a built-in AI assistant named Quill. It is a modern Final Draft alternative where AI helps you brainstorm, edit, and polish your script, but never writes it for you. Import and export Fountain and Final Draft, work offline, and keep full creative control.
AI that suggests, never writes for you
Most "AI screenwriting" tools are generators: you type a logline and they spit out pages. Inkwell is the opposite. It is a screenplay editor first, with Quill sitting alongside you as an assistant. Quill can brainstorm, suggest dialogue, or help restructure a scene, but it only ever proposes. Every change appears as a diff you explicitly approve or reject.
That means the words on the page are always yours. You own everything you write in Inkwell, using Quill does not transfer authorship, and your scripts are never used to train AI models.
What makes Inkwell different
Quill, your built-in AI assistant
Quill lives inside the editor. Ask it to brainstorm a beat, punch up a line, or untangle a scene. Every reply is a suggestion you approve or reject, never an auto-rewrite of your page.
An editor, not a generator
Inkwell is a real screenplay editor for writers who write their own work. Quill assists; you author. Nothing is generated behind your back, which keeps your process WGA-friendly.
Approve or reject every change
Inspired by the diff workflow in modern code editors, Quill shows exactly what it wants to change before anything touches your script. Accept it, tweak it, or throw it away.
Fountain & Final Draft support
Import and export Fountain and Final Draft (.fdx) with formatting, scene numbers, notes, and dual dialogue preserved, so Inkwell drops into an industry-standard workflow.
Works offline
Writing, formatting, import/export, and file management all work with no internet. You only go online when you choose to ask Quill for help.
Native on macOS
Inkwell is a fast, native Mac app, not a browser tab in a wrapper. It feels like the rest of your Mac and stays out of the way while you write.
