Fact Explorer is a chat-style, Q&A experience in Mary that allows you to ask natural-language questions about your matter and receive clear, structured answers that are fully traceable back to the underlying facts and source documents.

It is designed to help you interrogate your matter, analyse the facts, and verify Mary’s answers in an instant.

What kinds of questions can I ask?

You can ask any natural-language question about your matter.

Example questions

• Summarise the key issues in this matter.

• Did John have any pre-existing conditions?

• Who were John’s treating doctors before 2015?

• Are there any inconsistencies in John’s account of the incident?

• What agreement governs the relationship between the parties?

• Were there any defects in the goods delivered?

Follow-up questions

You can:

• ask follow-up questions based on a previous question and/or answer, or

• ask entirely new questions about the same matter.

How answers are presented

Each answer is optimised for clarity and fast review, and is split into two sections

1. Summary answer

A concise written answer designed to comprehensively answer all queries, while ensuring fast review. We recommend including the structure you would like your answer in, where there is one, to get the best results for you (e.g. please outline John pre-existing conditions, splitting them into a table of physical and psychological conditions.”)

Inline citations

Every sentence includes inline citations.

Citations are clickable and link directly to:

• the underlying facts in Mary, and

• the exact source document pages those facts come from (which open side-by-side once a citation is clicked)

This allows you to verify any statement in Mary’s answer in one click.

2. Cited facts

All facts used to answer the question are shown beneath the summary answer as cited facts. These are collapsed by default and can be expanded for deeper review.
