Your book on one grid
Every scene, its point of view and the threads that run through it, laid out so the sag in chapter twelve shows itself.
A free writing app that shows you the structure of your book (its scenes, threads and characters) over the files you already write in. Made by a novelist who is also a software engineer.


Every scene, its point of view and the threads that run through it, laid out so the sag in chapter twelve shows itself.

Each subplot traced across the book, so nothing goes missing and nothing arrives unearned.

What each character carries from scene to scene, and where they turn.
Open the one that fits the question you have today. They all read from the same story, so a change in one shows up in the others.
Every reference, line, image and idea you keep, shared across all your stories. Tag them, search them, and link them into any story.
Cards in lanes named after your structure: acts, parts, chapters, or your own. Drag ideas in before a single scene is written.
Scenes across the top, threads down the side. See what you planted, where it returns, and where a thread goes quiet.
Follow one storyline from first mention to last. Plants, payoffs and reversals are marked, and a broken link is flagged.
Characters and places, joined by the scenes they share. Spot the loners and the pairs that never meet.
The whole draft as one scroll, first line to last. Select a passage to see its threads, then open it in your own app.
Leathercase reads the files you write in and never changes them. What it adds is markdown and JSON beside your stories, readable without it, today or in twenty years.
Connect your own assistant if you want one. You see everything it touches, and it never writes prose.
