Uses 2x fewer tokens than the docx skill", "summary": "A new DOCX plugin for Cowork and Codex uses 2-5x fewer tokens than traditional docx skills by converting documents bidirectionally between DOCX and HTML, enabling AI to operate on HTML. The plugin's novel html->docx conversion addresses a gap in existing libraries, and it has been used internally for redlining legal documents.", "body_md": "Hi HNers,\n\nI'd like to share our DOCX plugin for Cowork and Codex.\n\nIt uses 2-5x fewer tokens compared to the traditional docx skill because it doesn't write any code nor execute python/node script. It is also much more reliable.\n\nOur DOCX plugin converts docx<->html bidirectionally. This means AI only operates on HTML. AI is excellent and very efficient when it comes to HTML.\n\nMost libraries (if not all) support docx->html, but none supports html->docx. This is what is novel about our approach.\n\nHere's the demo: [https://drive.google.com/file/d/1UNlUJYwkNX3NiANDkLLb3UoRSms...](https://drive.google.com/file/d/1UNlUJYwkNX3NiANDkLLb3UoRSms2dXCU/view?usp=drive_link)\n\nWe've been using it in-house for redlining legal documents, and we love it.
