StorySplice is built by Colin Urban at Threadlimit.co. I'm a software developer and writer who has spent years working at the intersection of technology and creative tools. I built StorySplice because I believe AI should enhance human creativity, not replace it — writers deserve tools that suggest, draft, and expand while leaving every final decision in human hands.
Interactive fiction has a long history, from early text adventures to modern tools like Twine. But most existing tools either require learning a programming language or offer no AI assistance at all. I wanted to create something different: a visual editor where you can see your entire story structure at a glance, with AI that understands narrative flow well enough to help you branch, expand, and write — without ever overriding your creative vision. StorySplice grew out of a simple question: what if turning a short story into a branching adventure was as easy as pasting your text and letting AI find the natural decision points?
StorySplice is a web-based visual editor for creating branching interactive fiction. You build a story as a map of connected scenes where each scene can lead to multiple reader choices. The visual story map lets you drag, zoom, and rearrange scenes to see every path and ending at a glance. Readers then play through your published story, making decisions that shape the narrative. StorySplice works in any modern browser with no installation or downloads required, and your stories are always exportable — no lock-in.
StorySplice combines a visual drag-and-drop editor with AI that understands narrative structure. Features like Splinter (which finds branch points in existing linear text and generates a full branching structure) and Branch Wizard (which creates multiple diverging paths from any scene in a single action) are unique to StorySplice. Unlike code-based tools, you never write a line of code. Unlike simpler editors, you get AI writing assistance with multiple model choices, story validation that catches orphan scenes and broken links, reader analytics showing how audiences navigate your stories, and Twine/Twee import and export for interoperability with the wider interactive fiction ecosystem.
