What it solves

Vela is a production-grade IDE designed specifically for long-form fiction and web novel authors. It solves the struggle of maintaining consistency in massive stories by integrating AI-driven drafting with a local knowledge base, preventing "character collapse" or plot holes that often occur in traditional text editors.

How it works

It functions as a local-first desktop application (Electron) that allows authors to bring their own API keys (BYOK) for various LLMs. The system combines a structured writing pipeline—moving from worldbuilding and outlining to drafting and reviewing—with a local RAG (Retrieval-Augmented Generation) system using SQLite and a vector engine to recall relevant story settings and character details automatically during the writing process.

Who it’s for

Creative professionals, indie writers, and web novel authors who need a high-productivity environment to manage complex world-building and long-form narratives.

Highlights

• End-to-End Pipeline: Integrated tools for worldbuilding, automatic outline generation, streaming chapter drafting, and a three-stage post-processing loop (Rewrite $\rightarrow$ Refine $\rightarrow$ Review).
• Local RAG Knowledge Base: Supports bulk importing of millions of words of reference material with semantic vector search to ensure narrative consistency.
• Extensible AI Integration: Native support for OpenAI, DeepSeek, Gemini, Claude, Ollama, and the Model Context Protocol (MCP) for custom tool extensions.
• IDE-Grade UI: A professional workspace featuring resizable four-pane layouts, deep dark themes, and comprehensive LLM usage analytics.
