QuillRune is a minimalist, AI-assisted novel studio that turns fragments into chapters fast. Start with an Outline: type a premise and let AI generate titled, editable beats you can reorder—then link each Chapter to a beat for clean structure. Drop in a fragment to get three streaming draft versions, merge the best parts, and refine with a floating AI panel or “//” inline chat that inserts replies at the cursor. Build Characters and World Notes with AI, auto-summarize on save, export as TXT, and write in a premium black-white-gray UI with Light/Dark themes.
