steven-tey/novel is an open source project that adds AI autocomplete to a Notion-style WYSIWYG editor (a way of editing documents by manipulating the visible screen as it is). It is written in TypeScript and is published under the Apache-2.0 license. The latest release is novel@1.0.2. However, the research record contains no changelog for this version, so no newly added or changed features can be confirmed. What can be confirmed from public materials is limited to the editor's composition, how to use it, and how it is distributed.
The README describes the editor as a Notion-style WYSIWYG editor that provides AI-based autocomplete. Autocomplete is the feature that continues the sentence you are writing. It is built around React and uses Next.js and Tiptap, among others. It states that you can deploy it to Vercel or run it locally. The repository was created on 2023-03-21 and has 16455 stars. The official editor targets React, but community packages for Svelte and Vue also exist, so there is a way to use it in other frameworks.
The only material for a judgment is the research record's momentum score of 3.2, and no novelty, technical or quality scores were given. There is also no data on which AI provider the autocomplete goes through, or on how accurate the completed sentences are. There are no performance measurements, adoption cases, or comparisons with other editors either. So the project is worth treating as an editor skeleton that can be tried right away in a React environment, but how much AI autocomplete actually helps with real writing cannot be concluded from the current material alone.
