Word in web is a pure JS docx editor/renderer benched against MS Word directly. This was largely inspired by Eigenpal going closed source, and some personal frustrations I had with working on complex Word templates, pleading papers, etc... and not having a clean way to view/edit them without owning MS Word (which I did just eventually buy but it sucked).This was also an exercise in highlighting the value of good evals for Agents to bench against. Instead of just throwing the OOXML standard at an agent and letting it spin, I put together a large corpus of Microsoft Word docs - converted them to a pdf and then rasterize them to images. I then compared the image diffs measuring the actual differences in the actual pixels. This let me catch a lot of the edge cases and optimize aggressively while preventing whack a mole style regressions that would have made this project a lot harder.
