Novel

Novel is an open-source, Notion-style WYSIWYG editor that combines structured rich-text editing with AI-assisted writing. It is built around Tiptap and ProseMirror, giving developers an extensible document model rather than a simple text area. Writers can compose and format content visually while requesting generated continuations through OpenAI-powered autocompletion. The project is designed primarily for React and Next.js, with community packages extending support to Vue and Svelte. Its interface and editor components can be reused inside publishing tools, note applications, knowledge products, and custom content systems. Vercel Blob can support uploaded content, while the Vercel AI SDK handles streamed model responses. Novel can run locally, deploy to Vercel, or serve as a starting point for a customized AI writing experience.
