The writing partner inside Inkwell

Quill helps. You decide.

Quill is a chat-based writing partner that already knows your script. Ask it to brainstorm, punch up a line, or catch a voice that's drifted. Every idea comes back as a diff you accept or reject. It never writes a word you didn't approve.

Try the diff on the right. Accept or Reject, it's your call.

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.

Suggested change · accept or reject
INT. THE PARTNERSHIP - DAY

Three steps, and you're always the last one.

01 · Ask

Talk to it like a script editor.

Quill has the whole script in context. Ask for a sharper twist or three takes on a line. No pasting pages into a chat window.

02 · See the diff

Its idea lands as a proposal.

Changes arrive in your script as a diff: green for additions, red for cuts. Shown, never applied.

03 · Decide

Accept, reject, or rewrite.

The page changes only when you say so, line by line or all at once. Undo anytime. The voice on the page stays yours.

Where most AI tools lose writers

What Quill won't do.

The reason to trust a writing partner is knowing its limits. Here are Quill's, on purpose.

It never writes for you

Quill suggests; it doesn't author. Every idea needs your explicit approval before a single character lands on the page.

It doesn't train on your scripts

Your work is never used to train AI models. Only the snippet needed to answer is sent for processing, with data opt-out protections.

You own everything

Using Quill doesn't transfer ownership or create shared authorship. Legally, it's the same as using spell-check or a thesaurus.

It stays out of your way

No autocomplete hijacking your cursor, no pop-ups mid-sentence. Quill is a chat partner that acts only when you ask it to.

INT. THE WRITERS' ROOM - DAY

Useful, specifically.

Not a blank-slate chatbot. A partner grounded in the script in front of you.

Make sweeping changes, safely

Rename across 90 pages, and approve each one.

Big edits arrive as a stack of diffs. Wave them through at once, or vet them one at a time. Nothing is irreversible.

Brainstorm in context

Get unstuck without leaving the page.

Ask for a sharper beat or a different take, grounded in what you've actually written.

Quill flags a line of dialogue that has drifted out of character
Guard your voice

Catches a line that drifts out of character.

Quill learns each character's cadence and flags the moment one stops sounding like themselves.

Always grounded

It reads your script first, every time, so suggestions sound like your draft, not generic AI prose.

No copy-paste · no blank-slate chatbot
