Novel

Novel is an open source, Notion style WYSIWYG text editor with AI powered autocompletion. It gives developers a block based rich text editing experience, where content is composed with slash commands and formatting menus, and an AI model can continue or complete the text being written. The project's own title describes it as a Notion style WYSIWYG editor with AI powered autocompletions. It is built for developers who want to add a polished writing surface to their own web application rather than for end users looking for a standalone notes app. The project ships a documentation site and a demo, and the code can be deployed to Vercel in one step or run locally. The setup instructions call for an OpenAI API key for the autocompletion feature and a Vercel Blob token for image uploads, so teams bring their own model and storage credentials. The repository notes support beyond a single framework. Novel is free to use as open source software, and the site publishes no paid plans or pricing page. Costs depend on the model provider and hosting a team chooses to connect, such as the usage billed by OpenAI for the autocompletion calls.
