A Claude Cowork and Codex plugin that creates and modifies DOCX files locally. You will save tons of time when your Cowork can manipulate docx files directly. This plugin uses 2-5x fewer tokens than the Anthropic's docx skill.

You can use our DOCX plugin together with Claude for Legal to enable a more seamless experience of working with a docx file!

Capabilities:

Read the content and the comments.

Create a new docx file. Optionally, you can use an existing docx file as the template. The styles will be copied from the template.

Add tracked changes to an existing docx file.

Add comments and reply to comments.

We've developed the DOCX engine from the ground up to work well with LLM. Our engine consumes much fewer tokens, faster, and more reliable than the current alternatives.

We are using this plugin at LegalRabbit to speed up our legal services. Try it out and let us know if you have any questions.

The plugin works offline, ensuring data privacy and security of your DOCX files.

Example prompts
