Overview

 

Upon opening Matter AI, you will be greeted with a welcome message.

Details of the current matter will appear in the top right corner of the window. 

At the bottom of the window is the chat box where you will be able to ask Matter AI questions relating to the current matter.

To get started, type your question or prompt in the chat box and click  or press Enter to send.

Suggestions

You may also select one of the pre-populated Suggestions provided by Matter AI. These suggestions are based on the matter type and the correspondence within the current matter. Suggestion prompts update in real-time depending on the previous questions you've already asked.

Model Selector

Choose from a range of leading AI models, including ChatGPT and Claude variants, to match the capabilities required for your task.

Different matters call for different levels of reasoning, speed, and depth. With the Model Selector, you can opt for a faster model for straightforward queries or a more advanced reasoning model for complex legal analysis.

Click on the model selector dropdown below Ask me anything and select from any of the following models: 

  • GPT 5.4 - Instant
  • GPT 5.4 - Thinking
  • Claude 4.6 Sonnet
  • Claude 4.6 Opus

All Agent

Matter AI now has a dedicated All tab, separate from your standard Matter AI Chat, that serves as a purpose-built workspace bringing together agentic chat, deep thinking, and LawY-powered research in one place. The All agent reasons through your question step by step, transparently showing its thinking as it works, and automatically draws on LawY when your query calls for it, returning cited, authoritative legal sources alongside its answer.

  • Open Matter AI
  • Select All at the top of the window

  • Click the + icon and toggle on Research.

  • Type your query.
  • The AI will respond drawing on LawY research if 'Research' and your question calls for it.

Prompts

The Try a prompt for that box provides a curated list of legally pre-drafted AI prompts from LEAP’s AI Prompt Library, based on the query you have entered. When a highly relevant AI Prompt is available from the Library, it will be suggested to you. If the suggestion is not needed, it can be dismissed.

If you decide to use a suggested Prompt, you can do so easily by clicking on the suggestion. The Prompt document will then open and automatically run. For more information on LEAP’s Prompts, see Matter AI for Word.

The time it takes Matter AI to respond is determined by the complexity of the answer and not by the number of correspondence items within the matter.

 

For instance, if the answer contains extensive information or involves any calcuations, Matter AI will require additional time to generate the response.

Reviewing References

 

Depending on the questions asked, answers provided may include references to correspondence items where the origin of the information has been retrieved by Matter AI.

If the Matter AI response has multiple correspondence items attached to the reference, you can click the + icon next to the reference to view all correspondence items used.

To view any of the references, click on the document or click on for more options including Open, Chat about this document or Preview. 

You can start a new chat about a specific reference document by with the Chat about this document option. This will open a new chat with the reference document highlighted in the top right corner. 

The Preview option will open the document within the Correspondence Preview window. You will also be able to view all correspondence items on the matter in the left pane.

Regenerate Responses

 

You are able to regenerate any of the Matter AI generated responses by clicking the Regenerate icon in the bottom left corner of the response.

Canvas

Canvas now gives users more control over the AI generated content. You no longer have to regenerate full responses to tweak a paragraph. Canvas turns the AI output into an editable canvas, allowing you to improve, add or remove text in the response based on the selected text and instruction used.

You can use Canvas by clicking on the relevant section of text in the AI response and then select:

  • Ask Matter AI: Ask follow-up questions or provide new instructions specific to the selected text
  • Regenerate : Matter AI will regenerate the selected text
  • Delete : Remove any part of the selected text response that you don't want
