Everything you need to plan, write and finish your book
Bookh brings planning, drafting, story memory and export into one writing studio, built around your voice rather than the AI’s.
From spark to outline
Give your story a spine before you face the blank page.
Premises from a single line
Write your own premise, or set genre, themes, cast, tone, point of view and tense, and choose from AI-suggested premises written like back-cover hooks.
Back-cover synopsis
A narrative synopsis that honours your chosen tense, cast and point of view, so you know the shape of the book before chapter one.
Chapter outline with scene beats
A dramatic arc from setup to resolution. Rename, reorder, add or delete chapters, regenerate one chapter or the whole outline.
A writing studio, not a chat window
A distraction-free manuscript editor with help one keystroke away, and out of the way when you don’t want it.
Manuscript editor
One chapter at a time in a calm reading column, with a chapter and scene outline on the left and focus mode when you need silence.
Mentor chat
Ask about pacing, motivation or what happens next. The Mentor knows your book, so its answers are about your story, not stories in general.
Copilot, toolbar and / commands
Inline AI copilot suggestions as you type, a selection toolbar for quick edits, and slash commands for everything else.
Story tools
The memory and structure a long book needs, folded into the editor.
Lore Vault
Characters, places, items and events that Bookh remembers and auto-detects from your chapters. The cast you enter during setup is seeded automatically, so your story bible exists from day one.
Relationship graph
See how your characters connect: allies, rivals, families and secrets, mapped from your Lore Vault so you can spot the threads you forgot to pull.
Plot-Beat Canvas
Lay out your plot beats on a canvas to see the shape of the story and keep the midpoint, climax and resolution where they belong.
Voice & Style
Bookh analyses your manuscript and sets a voice profile, including maturity and tone, so AI drafts and suggestions sound like you.
Writing tools
For the days the words come slowly, and the days you need to check they are really yours.
Writing Lab
Draft the next few paragraphs from where you are, then keep, edit or discard them.
Finish Chapter
Continue a chapter in your voice, tense and point of view when you know where it ends but not how to get there.
Originality check
Spot passages that read like AI and rework them so they read like you.
Image Generator
Sketch a cover idea or picture a scene to keep your imagination and your descriptions in step.
Dictation & Read Aloud
Speak a scene when typing feels slow, and listen back to hear the rhythm of your dialogue.
Everyday essentials
Pomodoro timer, word count, quick notes, version history, find & replace and focus mode.
Export like a book
Preview your manuscript as a formatted book, then take it wherever it needs to go.
How it works
Three steps from an idea to a manuscript.
Tell Bookh your idea
One sentence, a genre and a length. Add your cast, tone and tense if you know them.
Shape the story
Edit the synopsis and the chapter outline until the plan feels like your book.
Write and export
Draft chapter by chapter with the Mentor and story tools beside you, then export.
Made for every kind of story
Fiction, memoir and screenplays, with the interface in six languages.
