Rhyolite: A Node-Based Algorithmic Writing Environment for Novels and Technical Research

Rhyolite is an open-source node-based algorithmic writing environment designed to address the pain points of managing complex structures in novel writing, worldbuilding, and technical research. It integrates a terminal-style interface, a DAG timeline engine, a hybrid RAG system, and multi-model AI support, treating narratives as computable graph structures and allowing creators to manage stories and knowledge like code.

Traditional writing tools face contradictions: simple text editors cannot handle complex narrative structures and knowledge networks, while complex content management systems are too bloated and disrupt creative flow. Existing AI writing assistants mostly follow the "smart typewriter" paradigm, which struggles with multi-threaded narratives, character relationship networks, and worldbuilding with interwoven timelines. Rhyolite was born to solve these problems.

Rhyolite's most innovative feature is the DAG timeline engine. It uses a Directed Acyclic Graph (DAG) instead of linear/branching timelines, supporting arbitrary node relationship networks:

• Nodes: Represent events, scenes, knowledge entries, or hypotheses, divided into narrative types (Event/Scene/Lore) and technical types (Hypothesis/Evidence/Conclusion).
• Edges: With semantic labels (e.g., "causes", "refutes") indicating causal, temporal, or logical dependencies.
• Interaction: Double-click to create nodes, drag to connect nodes, edit edge labels, etc., with grid snapping support. This design allows creators to easily manage complex narratives such as multi-perspective interleaving, flashbacks, and interludes.

Rhyolite's AI assistant deeply integrates the project's knowledge structure and automatically assembles four layers of context:

1. Core Canon: Includes the lore Bible and story outline.
2. Keyword RAG: Substring matching based on titles/aliases, with fast response.
3. Embedding RAG: Uses Gemini text-embedding-004 to generate vectors for semantic similarity retrieval.
4. Graph Traversal RAG: Reverse BFS traversal from the current node up to 10 hops, including node content, summaries, and edge semantics to understand complex causal chains. Additionally, an intelligent chunking strategy handles long documents, and real-time token budget display (Canon/Wiki/DAG/Draft/History) helps control AI attention.

Interface Design: Terminal-style (ultraviolet color scheme, CRT glow effect, Monaspace Neon font), three-column layout ([DIR] Project Directory / [EDIT] Editor / [COMMS] Assistant Panel) to reduce visual distractions. Multi-Model Support: Compatible with Gemini, OpenAI local models (Ollama/vLLM), and Anthropic Claude. AI personas (model selection, temperature, system prompts, etc.) are defined via the "Glyph" system. Data Storage: Pure file storage (Markdown/JSON) without databases; automatic version history (.history directory); high portability, supports Git management, and is long-term readable.

Rhyolite is suitable for three types of scenarios:

1. Novel Writing: Track events from multiple character perspectives, manage flashbacks and interludes, and ensure consistency of foreshadowing.
2. Worldbuilding: Use Artifacts to store setting details, timelines to record historical evolution, and AI to assist in checking setting consistency.
3. Technical Research: Nodes represent hypotheses/evidence/conclusions, edges mark relationships, and arguments are automatically synthesized.

Current Limitations:

• Learning Curve: The concepts of DAG and graph traversal have a threshold for non-technical users.
• Limited mobile support and lack of real-time multi-person collaboration features. Future Directions:
• Plugin System: Community-extended functions.
• More export formats (EPUB/PDF/Word).
• File synchronization-based collaboration features.
• Visualizations such as story structure heatmaps and character relationship networks.

Rhyolite is an innovative exploration of writing tools, treating narratives as computable structures and using graph theory and AI to assist in complex creation. It is not suitable for simple linear narratives, but provides a powerful solution for creators who need to manage complex structures, multi-threaded narratives, or knowledge associations. In an era of homogenized AI writing tools, Rhyolite persists in focusing on specific pain points, making it a noteworthy presence in the creative tool ecosystem.
