Describe the moment, not the whole book
You do not need to paste a manuscript to keep a story going. One or two lines about where it stands is enough: who is in the scene, what just happened and what you want to happen next. The AI asks what it still needs to know, such as how your lead feels about what just happened, or whether the next chapter should calm things down or make them worse. Answer, type your own, or skip.
A next chapter, and the ones after it
Set the heat and the length, then choose a writer. Spicy is chosen on this page because momentum is what a stalled draft needs, but Pyra, Onyx and No Writer are there if your story has a different voice. The chapter is written in the full writing app after a free sign-up, and from there the story can go on as long as you like. Every new chapter remembers the names, secrets and promises of the ones before it, so the story stays consistent instead of starting over each time.
