## Overview

Arcweave is a browser-based platform for designing branching narratives, quests and dialogue trees as visual flowcharts, with lore, components and assets in one shared project. You can playtest a story inside the app before it touches your engine, then pull it into Unity, Unreal or Godot with free, open-source plugins that sync in real time.

Its AI tools include a text generator that writes new story elements in the existing tone and lore, a design assistant that analyzes flow, pacing and character arcs and finds dead ends or inconsistencies, and a text enhancer for rewrites and alternate versions. In October 2026 Arcweave added a hosted MCP server so Claude, Cursor, Codex, Gemini CLI or VS Code can summarize, inspect and edit projects or export them for your engine.

## Key features

- Visual editor for branching dialogue, quests and logic
- AI text generator that follows your story's tone and lore
- AI design assistant that finds dead ends and inconsistencies
- In-app playtesting before engine integration
- Free open-source plugins for Unity, Unreal and Godot with real-time sync
- Hosted MCP server and REST API (Team plan)

## Use it for

- Have AI audit a big dialogue tree for dead ends and plot holes
- Let your coding agent read and export narrative content into your game
