Stop wrestling with spreadsheets. Start designing stories visually.StoryFlow Editor is a visual node-based narrative design tool for creating branching dialogue systems, interactive stories, and complex game narratives. Built with a Blueprint-style visual scripting interface familiar to Unreal Engine developers - no coding required.Connect dialogue nodes. Create branching choices. Add conditional logic. See your entire story structure at a glance. Test any path instantly without leaving the editor.56 Node Types for complete narrative control:Dialogue & Flow: Dialogue nodes with images and audio, branching choices, script jumpingVariables: Booleans, integers, floats, and strings with full get/set operationsLogic Gates: AND, OR, NOT, comparisons, random selectionMath Operations: Plus, minus, multiply, divide for dynamic valuesString Tools: Concatenate, contains, length, case conversionCharacters: Character system with custom variables per characterVISUAL STORYTELLING MADE SIMPLEDesign narratives the way you think about them: visually. Every story element - dialogue, choices, conditions, variables - connects through an intuitive drag-and-drop interface.See the Big Picture: Your entire narrative structure displayed as an interactive graph. Instantly spot dead ends, identify logic errors, and understand complex branching at a glance.No Code Required: Writers, narrative designers, and solo developers can build sophisticated dialogue systems without programming. Connect nodes, set conditions, and your story logic works.POWERFUL VARIABLE SYSTEMTrack player choices, manage game state, and create reactive narratives with a complete variable system:4 Variable Types: Booleans, integers, floats, and stringsGlobal & Local Scope: Variables that persist across scripts or stay containedCategories & Organization: Group variables logically, search instantly, drag to reorderConditional Dialogue Options: Show or hide choices based on any variable conditionBuild systems for: relationship tracking, inventory management, quest progress, dialogue flags, numerical stats, and more.CHARACTER SYSTEMCreate and manage characters directly in your project:Define characters with names and custom variablesAttach characters to dialogue nodesRead character data dynamically with Get Character Variable nodesCharacter data exports cleanly to JSON for game engine integrationFULL AUDIO SUPPORTBring your narratives to life with complete audio integration:Import MP3 and WAV files into your projectAttach audio to dialogue nodes with in-editor previewLoop option for background music and ambient soundsDedicated Play Audio node for triggered sound effectsVolume controls in the runtime playerAudio automatically included in HTML and JSON exportsTEST WITHOUT LEAVING THE EDITORRuntime Debugger lets you playtest instantly:Play from any node - jump directly to problem areasWatch variables update in real-time as you make choicesSee the call stack to understand script executionCatch logic errors before they reach playersNo export required. No external tools needed. Click play, test your story, iterate immediately.EXPORT OPTIONSHTML ExportCreate standalone interactive web experiences that run in any browser:All dialogue, logic, variables, images, and audio packaged togetherShare with anyone, publish on itch.io, embed in your portfolioPerfect for prototypes, demos, and complete visual novel experiencesJSON ExportFull data export for game engine integration:Clean, readable JSON maintaining your folder structureComplete story data: nodes, connections, variables, characters, audio referencesReady for Unity, Unreal Engine, Godot, or custom enginesOfficial engine plugins in active developmentDESKTOP-FIRST DESIGN100% Offline — Your data stays on your machine.
