Book to screen

Turn a whole book into a first draft.

Adapting a novel is the longest road in screenwriting. Bosswriter reads the entire manuscript and adapts it scene by scene into a formatted, first-draft screenplay, a rough cut you can shape into something yours.

The manuscript312 pages

Maya had not been back to the bakery since the funeral. The key still fit the lock, stiff but willing.

Inside, the smell of cardamom and burnt sugar pulled her straight back to a childhood she had spent years trying to leave behind.

She set down her bag and let the door swing shut.

INT. THE BAKERY - DAY

Dust sheets the counters. MAYA stands in the doorway, key still in hand.

MAYA

It still smells like him.

Complete story

It reads the whole book

Most tools skim or chop a book into fragments and lose the thread. Bosswriter holds the entire story in mind, so every scene it writes knows where the book has been and where it is going.

Cover to cover

It takes in the entire manuscript, not a chunk or a summary, so nothing important slips through the cracks.

Whole-story memory

Every scene it writes is made with the full book and the draft-so-far in mind, so the adaptation stays coherent start to finish.

A point of view

It forms an adaptation strategy first, what to keep, invent, and cut, instead of transcribing the book page by page.

The adaptation, scene by scene

It works like a screenwriter would, in craft-focused passes, not one giant translation.

Find the story's DNA

The dramatic spine, the central question, the conflicts, the genre, and the themes that actually drive the book.

Set the adaptation strategy

A filmmaking point of view: what to elevate, what to invent for the screen, what to cut, and the visual language to carry it.

Choose the right scene count

It works out how many scenes the story actually needs to land its arc, rather than forcing an arbitrary number.

Write every scene with a purpose

Each scene is built around a want, an obstacle, stakes, and subtext, so it earns its place in the story.

Run a script-doctor pass

Every scene gets a polish for sharper dialogue, clearer visuals, and tighter pacing.

Check the whole arc

It steps back to validate pacing, character growth, and rising conflict across the entire screenplay.

Genre-aware

Adapted for its genre

A thriller is built differently than a love story. The adaptation applies the craft the book's genre calls for, from escalating tension to quiet transformation.
