Description
I started building this 10 months ago, largely using agentic coding tools. I've stayed very involved in the code base and architecture, and have never moved faster in my life as a dev.The word processor engine and rendering layer are all built from scratch - the only 3rd party library I used was the excellent Y.js for the CRDT stack.Would love some feedback!

Could you build this?
No Building a custom word processor rendering and editing engine from scratch that faithfully supports complex layout, pagination, text measurement, and Word document specifications is a massive systems-level engineering undertaking.
What it would actually take: Requires an in-browser canvas or custom DOM layout engine handling typography, hyphenation, inline elements, selection models, and bidirectional text rendering. Building compatibility for Microsoft Word formats (.docx XML specs) alongside reliable pagination and diffing requires specialized software engineering in document engines similar to Google Docs or LibreOffice.
