Build an Argument

Ask our AI to build a legal argument in defence or opposition to a statement, with citations.

Where “Answer a Question” gives an objective answer, “Build an Argument” is more opinionated — much like a litigator. Vincent AI harnesses the power of Generative AI to analyze legal documents and use this knowledge to build arguments, including anticipating the claims that opposing counsel will make and automatically creating counter-arguments. Lawyers can use this information as the basis of legal briefs, client letters, or any other legal communication.

Build an argument

To get started, click the blue 'Vincent AI' button on the top bar, then select 'Build an Argument'.

On the left, you can see your history. If you select any of these queries, it will show you the results it showed you before. As this does not re-run the search, it does not count as a new query. You can collapse your history by clicking the icon above it.

Select the jurisdiction (including a region or state) you are interested in, whether you wish the argument to be in support of or in opposition to your statement, and type your statement into the box. When you first enter the page, the jurisdiction will match your default search jurisdiction, if it's available from the list.

You can currently select from Australia, Canada, Chile, the European Union, Ireland, Mexico, Singapore, Spain, the United Kingdom, the United States, Colombia* and New Zealand*. We will be adding more jurisdictions soon.

*Available on request

When you are ready, press 'Submit Question'. The answer may take a minute or two to generate, as Vincent is searching all of our legal content for the best argument in response to your statement. We will email you once this has been fully generated, so if you wish to continue your work while you wait, you don't need to worry about losing your answer.

You can also edit your statement if you feel you haven't worded it correctly. However, do bear in mind that this will submit a new query.

Your argument will be displayed on the left-hand side of the screen, with a full list of the authorities Vincent has cited available on the right.

If you are trying to put together an argument in defense of a statement, try asking Vincent to create the argument in opposition to it so that you can better prepare!


The answer to your argument request will be split into a short summary, followed by a breakdown of the most relevant materials and any exceptions and limitations related to the point.

You can download the answer in either PDF or Word format and copy it to your clipboard by clicking the icons above the answer.

At the bottom, you can rate how well you feel Vincent has argued the point.

On the right, you will see a full list of all the legal texts Vincent has used to create your answer. These will be split by text type. This will include texts that may no longer be in force or have been overruled as they could still be relevant to the question.

For each text, you will see the link, a summary of the passage, and a short excerpt from the text itself. You can copy any of these summaries to your clipboard by selecting the icon at the top of the text listing. If there are any relevant treatment types or if a piece of legislation is no longer in force, this will also be shown in the summary.

At the top of the page, you can either collapse the list to see just the text titles or choose to modify the texts used to answer the question.

For example, if you feel that one or two of the texts aren't relevant, simply select 'Modify list', de-select the texts you aren't interested in, and click 'Apply'. The answer on the left will then regenerate based on the new selection.
