How it works

Blank page to published in three stages.

1
Upload your voice sample
Paste or upload a few pages of your past writing. The studio builds a voice profile that captures how you actually write.
2
Generate your draft
Describe your book. Quick Draft writes a chapter outline and opens the manuscript in your voice. Keep going scene by scene or chapter by chapter.
3
Polish and publish
Run the Prose Validator, fix what it finds, design your cover, export KDP-ready files, and walk through the Amazon listing step by step.
Proof

The voice lock, measured.

Same beat, drafted twice by the engine: once with no voice sample, once with a 170 word sample loaded. The scores below come from the voice match and phrase scan that ship inside the Studio, run on these exact passages. Not a vibe. A number.

The writer's sample

"The gate hangs on one hinge and I let it. Dad would have fixed it the same morning. I count the cattle twice because the light is bad and because counting is easier than going inside. Thirty one. One short. … Tonight I pull a cow out of the water and call it a win because it is one."

As the golden sun began to set over the sprawling ranch, Daniel realized that something was amiss. One of the cows had wandered away from the herd, and a feeling of deep unease settled over him.

The count comes up short at dusk. Thirty one, and I run it again because the light plays tricks along the fence line. Still thirty one. I find her in the pond past the pecans, hock deep, chewing like the water belongs to her. The bank is soft. It takes my boot at the second step and I let it go, because a boot is cheaper than a fall. She does not run. They never run. They stand there and make you come get them, and you do, rope cold in your hands, breath showing…

The voice match compares sentence rhythm, punctuation habits, diction, dialogue share, and function word usage between your sample and the draft. It measures style agreement, not authorship, and it runs on every manuscript before publish.
