DeepQuill – Novel Writing Software That Understands Your Story

The Problem

Sound familiar?

You're 50,000 words in. Was Marcus's sister named Elena or Helena? Did he have a scar on his left cheek or his right? You know you wrote it down somewhere...

📑

Scattered character notes
Spreadsheets, wikis, sticky notes—your character info is everywhere except where you need it.
🔎

Endless searching
"Find in document" doesn't help when you can't remember what you wrote.
📋

Manual tracking is tedious
Every new detail means updating your notes. You're a novelist, not a librarian.

There's a better way.

DeepQuill watches as you write. It notices when you introduce a character trait, when two characters have a conversation, when the stakes change. It builds your character bible and story analysis automatically—and shows you character details right in your manuscript with hover cards. No switching windows. No breaking your flow.
