Vela

Vela is a desktop AI writing editor for novelists and web fiction authors who need to manage a long story's characters, settings and chapters. It brings planning, drafting and revision into one workspace.

• Story planning: Build world notes and character profiles, track character states across chapters, and generate outlines using structures such as the three-act model or hero's journey.
• Chapter drafting and revision: Generate prose from an outline and earlier context, rewrite selected passages or whole chapters, and request checks for grammar, plot logic, pacing and character arcs.
• Local reference library: Import reference novels, setting documents and character notes, then retrieve relevant passages automatically as you write.
• Model choice: Assign different models to drafting, polishing and reference retrieval, with support for Ollama, OpenAI, DeepSeek, Gemini, Claude and OpenAI-compatible APIs.

Vela runs on macOS, Windows and Linux and is open source under GPL-3.0. Project data and the reference library stay on your computer. Ollama supports offline model use; choosing a cloud provider requires an internet connection and your own API key, and sends the content used for that request to the provider. The workspace has resizable editor and AI panels, and MCP support lets it connect to external tool servers.
