Inkwell · AI that waits to be asked

A screenplay editor
that respects the writer.

Inkwell is a professional screenplay editor with a writing partner built in. Quill helps only when you ask: brainstorm a scene, punch up a line, or catch a voice that's drifted. Every idea arrives as a diff you accept or reject, and nothing changes without your say-so.

INT. LIGHTHOUSE - KEEPER'S ROOM - NIGHT

NORA hovers over the dead radio. Static swells. Then, underneath it, a voice.

NORA
We should call for help.
Nobody's coming. So we stop waiting.
Quill

You asked for a sharper read. Nora doesn't ask, she decides. Here's a take in her voice, as a diff.

Suggests · never applies

It asks first. Always.

Quill never auto-writes. Every idea is a suggestion you keep, dismiss, or write over.

Green & red

Nothing changes behind your back.

Bigger edits arrive as diffs in green and red. The page moves only the moment you say so.

Your voice, guarded

The script stays the one you wrote.

Quill learns how your characters talk, defends it, and leaves the final call to you.

INT. THE EDITOR - DAY

Everything the page needs. Nothing it doesn't.

Industry-standard formatting, outlining, notes, and a writing partner that already knows the script, all in one window.

01 · Approve

Approve every word before it lands.

Suggestions arrive as diffs: green for additions, red for cuts. Rename a character across 90 pages and approve each change, or wave them all through at once.

02 · Local-first

Writes on a plane. Writes on Wi-Fi. Either way.

A real desktop app. It opens instantly, saves locally, and never stalls waiting on a server. Quill only goes online when you ask. Your script never phones home.

Quill flags a line of dialogue that has drifted out of character
03 · Voice match

Catches the line that doesn't sound like them.

Quill learns each character's rhythm and tells, and flags the moment a line drifts out of character. A second read that guards your voice.

04 · Interop

Plays nicely with Final Draft.

Import and export .fdx, Fountain, and PDF. No scene number lost.

05 · Brainstorm

Stop re-explaining your story.

Set the room the way you write best

Four rooms. One muscle memory.

Light, Sepia, Focus, and Midnight. Industry-standard formatting holds under all of them. If you've written a script before, the keyboard already knows what you mean.
