The Noxtua Word Add-in: AI-powered document editing, right in Word

In the legal profession, every word counts. Hence, a significant portion of every legal professional's day is spent on exactly that – carefully writing and refining documents in Microsoft Word. It's meticulous work, and it should be. But it can be done with less effort.

Until now, using Legal AI to support document work meant constantly switching between tools – copy a passage, switch tabs, paste the result back, repeat. That friction adds up. It breaks your focus and gets in the way of the work that actually matters.

That's why we have built the Noxtua Word Add-in. 

Legal intelligence in Word, right by your side 

With the Word Add-in, you seamlessly integrate Noxtua's Legal AI into your document workflows in Microsoft Word – the environment where you already spend much of your time. It makes tool switching obsolete and avoids interruptions. It’s just you, your document, and Noxtua – all in one place.

The split-screen mode allows you to keep full control over your document on the left while Noxtua assists with research or editing in real time on the right. 

This is how the Noxtua Word add-in supports lawyers in their daily work with documents:

Legal research: Do you need to verify a legal point or research the context behind a specific passage? Select the text passage, ask Noxtua, and get precise answers backed by complete source references – without leaving Word.

AI-powered suggestions: Whether you're refining a single clause or overhauling the entire document – ask Noxtua to suggest improvements and decide exactly what makes it into the final version.

Change control: Because quality matters, every suggestion comes with legal reasoning explaining why the change was recommended. You can either auto-apply changes or accept or reject each one individually. All accepted changes are tracked directly in the document. 

The right tool for every stage 

With the Editor and the Word Add-in, Noxtua covers the full document lifecycle with each tool designed for a distinct stage of the process.

The Editor lives inside Noxtua and is built for the earlier stages: exploring legal arguments, structuring unsorted information, or drafting memos from your research. It's where ideas take shape.

The Word Add-in is built specifically for refinement and finalization. It combines Microsoft Word's document control with Noxtua's legal intelligence, so you can refine existing documents with precision and speed, right in your familiar environment.
