About 4i Author
Story Writer writes long fiction with you, one prompt at a time. You say what happens next; it writes the chapter — and it keeps writing, chapter after chapter, without losing track of who your characters are or what has already happened. HOW IT WORKS Set up a story with a background and a style guide. Past tense, close third, no em-dashes — whatever you want held to. Both are sent with every turn, so a change is felt from the next prompt onwards. Then write a prompt. The chapter arrives a paragraph at a time as it is written, so you can read it as it lands or put the phone down and come back to it finished. WHILE IT IS WRITING • Steer — add an instruction to the turn already running. • Stop — everything written so far is kept. • Queue — write your next prompts without waiting. They run in the order you put them in, you can reorder them, and nothing is ever discarded on your behalf. KEEPING A LONG STORY STRAIGHT • Facts — names, places and what is already true, carried into every turn. • Review — a pass that reads the whole story and reports contradictions in names, timeline and detail, then rewrites the parts you approve. • Chapters — jump anywhere in the story, with a running word count. ALSO • Attach photos to a prompt and have them placed in the story. • Brainstorm — give it a handful of words and it sketches three ways in. • Share the whole story as a text file whenever you want it out of the app. • A warm paper theme and a dark one, or follow the system. WHAT IT COSTS Five turns every day are free. After that a turn costs 0.001 credits and a whole-story review costs 0.02, so the smallest credit pack — 3.5 credits, about 3,500 turns — is probably enough for at least ten full stories of fifty chapters each, including the reviews and rewrites along the way. Credits never expire and there is no subscription. They belong to your 4i account rather than to this app, so they also work in the other 4i apps, and credits bought elsewhere are already here. THE ACCOUNT The writing runs on 4i's servers, so a free 4i account is needed and your stories live on it.
