We've made a Cowork docx plugin.

My friend and I provide legal services to startups. We've developed and used our in-house docx plugin for a long while and decided to share it publicly. It's 2-5x cheaper (i.e. uses 2-5x fewer tokens) compared to the Anthropic's docx skill. Mainly because it doesn't operate directly on the docx bloated structure and doesn't write code. The plugin works locally and free (since it works locally). No content is sent out of your machine (except sending to Claude since you are using Cowork, of course). No new interface nor UI. It's just Cowork that you may have already been using. \--- For our implementation story, we had used a regular chatbox (ChatGPT, Claude) for some time before we moved to Cowork. Cowork feels more natural because we can write our own playbook, use Claude For Legal, and use reference materials (other docx and pdf files). Cowork is also very smart in terms of chunking the doc and manages context. We've noticed drastically better quality in review because it uses/selects parts of playbooks appropriately. We would generate review in Cowork do redline on the docx file manually. Then, we installed the Anthropic's docx skill, which was okay-ish. It worked most of the times but took very long to finish and used up quota quite a lot. Eventually, we've developed our own docx plugin that transforms the bloated docx format to a simpler format (and vice versa i.e. bidirectional). It has been working quite well. It saves a lot of times and tokens. After redlining, we would open the docx file to review, make edits, and make further comments. Then, we would tell Cowork to address our comments in the docx file. Then, Cowork would handle the comments as if it was a real colleague! Several friends of ours have been using it successfully, and now we would like to share it with a wider audience.
