Plot Trellis - your plot as a tree and a mind-map

plot-trellis.skillsafe.ai

Clean

Build a novel's or story's plot as an outline tree - acts, chapters, scenes, beats - with the keyboard, and see it at the same time as a mind-map. Free in the browser: structure templates (three-act, kishotenketsu, hero's journey, seven-point, mystery), a scene balance meter, checks for orphan branches, duplicated cards, dangling setups and acts without a turning point, Markdown/OPML import and OPML, Markdown, SVG, JSON and print export. Paid: a structural critique that names gaps by branch and proposes add/move/merge/rename operations drawn as ghost cards you accept one at a time, then a re-critique after your edits. Structure method from @haowjy/story-architecture (haowjy/creative-writing-skills).
