Co-pilot writing

Write your novel with AI by your side

You are the author. The co-pilot suggests when you ask, remembers your characters and your plot, and never writes a word you did not accept.

Chapter 3The DiscoveryCo-pilot

Elena stepped into the ancient library, dust motes turning in the shaft of light from the high windows. The smell of old paper and leather filled the air.

She ran a finger along the spines. Third shelf from the top, the old man had said, bound in midnight blue.

Her heart went quick as she found it— the book seemed to pulse with an inner light, its silver lettering faint in the dim.

Your writing journey

Four steps from blank page to finished book

You stay in control at every one of them.

  1. 01

    Start writing

    Open a blank page and begin. The prose is yours, in your voice and your rhythm.

  2. 02

    Ask for a continuation

    A suggestion streams in at the caret in muted ink. Accept it, or keep typing.

  3. 03

    Refine what you wrote

    Select any passage to rephrase, expand or shorten it, and see the change before you keep it.

  4. 04

    Publish the book

    Export to EPUB, PDF or TXT, generate a cover, and share it with readers.

Co-pilot writing

With you, not instead of you

Write in your own voice and call for help on the sentence you are actually stuck on. Every suggestion arrives as pencil and needs one deliberate keystroke to become ink.

Write naturally

Type your story freely. The co-pilot only writes when you ask it to.

Suggestions at the caret

Ghost text streams in where you stopped, and stays pencil until you accept it.

Refine a selection

Rephrase, expand or shorten a passage; the original is struck through until you commit.

It remembers the book

Characters, open threads and established facts come from the chapters you already wrote.

AI portraits

Generated from the profile you wrote.

Character library

Write the people once

Define a character in detail, then reuse them across every story. The co-pilot reads those profiles, so the person who walks into chapter nine sounds like the one from chapter one.

Rich character profiles

Backstory, motivation, personality, appearance and speech pattern in one place.

AI portraits

Generate a character portrait in one click, on the plans that include image credits.

Reuse across books

Pick people from your library when you start a new story instead of rewriting them.

Consistent voice

The co-pilot reads those profiles, so dialogue keeps sounding like the person who speaks it.

Build your library

Built for authors

Everything the book needs, nothing it does not

No word counters that lie, no fake teasers, no feature that writes the book behind your back.

Suggestions on demand

Continuations, dialogue, description or a specific beat — always at your caret.

Character library

Reusable people with profiles the AI actually reads.

Story bible

Threads, promises and world facts derived from what you already wrote.
