What to ask before you buy

1. Does the zero-data-retention commitment apply to every model the product routes to, or only some?
2. What happens to a document I open in the assistant if I cancel?
3. Which Word and Google Docs versions does it support?
4. Is the price per seat, and does it change with document volume?

Limits in the record

• The vendor does not publish a firm-size scope in the checked source.
• The vendor does not publish a data-location statement in the checked source.
• It is a document-layer tool, so it does not cover the rest of a matter workflow.

How it sits in Drafting & review

Inside drafting and review, this is the Word-native option for a smaller buyer. Harvey is the enterprise alternative with a sales-led contract. For a solo or small transactional practice, the practical difference is that this one can be adopted inside the tool you already write in.

Reading the vendor’s wording

The vendor says it has negotiated zero-data-retention agreements with OpenAI and Anthropic, so customer data in requests and responses is not persisted and exists only in memory to process a request. It also states that its providers never learn from, train on, or store customer data.

How to evaluate it in a trial

1. Confirm the zero-data-retention commitment applies to every model the product routes to, not only some.
2. Test it on a real contract in the Word version you actually use.
3. Check whether the price is per seat and whether it changes with document volume.
4. Ask what happens to a document you open in the assistant if you cancel.

What adopting it costs

It works inside Word and Google Docs, so there is little to migrate. The document stays where it already lives, which keeps the switching cost low and the lock-in correspondingly low.
