aiR Assist (Advanced Access)

aiR Assist is a conversational search tool integrated within RelativityOne, designed to empower legal teams to interact with their data using natural language. By leveraging advanced AI, aiR Assist enables users to surface hidden insights, reveal connections, and uncover themes in moments directly within the Relativity platform. This transforms how legal professionals explore and understand modern legal data, leading to faster comprehension, stronger decision-making, and defensible outcomes.

It works by searching the extracted text of indexed documents. Users can create indexes per workspace supporting up to 50,000 documents. When a query is submitted, aiR Assist identifies the most relevant documents and uses a large language model (LLM) to generate answers, complete with citations to up to 25 source documents.

How aiR Assist works

aiR Assist operates using a Retrieval-Augmented Generation (RAG) process to deliver grounded, evidence-based responses. This approach combines document retrieval with large language model generation to ensure accuracy, transparency, and contextual relevance.

1. Indexing the documents (indexing step)
   The user identifies documents to query and creates an index.
2. Asking a question (question step)
   The user asks a question.
   
3. Finding relevant documents (retrieval step)
   Each question is matched against the text indexed from the identified documents. aiR Assist performs a similarity search to identify the most relevant content. The documents are divided into smaller passages, and the system selects the top results that best correspond to the question.
4. Generating the answer (generation step)
   The selected passages, along with the original question and system prompt, are passed to the LLM (GPT-4o). The model uses this retrieved context to generate a coherent, concise, and well-supported answer, including up to 25 citations and references to the original sources.

LLM model in use

aiR Assist currently uses the Open AI GPT-4o LLM, providing high-quality, contextually grounded responses supported by retrieved source material.

Important Limits

• Each index can contain up to 50,000 documents.
• Individual documents must be 5 MB or smaller; larger files are excluded during indexing.
• Only documents with extracted text are indexed. Files that do not contain extractable text are excluded automatically from the index.

Understanding aiR Assist responses

aiR Assist is designed to identify and summarize relevant information from large document sets through natural language interaction. The system operates on a Retrieval-Augmented Generation (RAG) architecture, which retrieves and analyzes the most relevant documents and generates a grounded response supported by citations and references.

aiR Assist focuses on returning the most contextually appropriate and evidence-based information rather than performing exhaustive or “find everything” searches. It does not review every document individually, and some occurrences of keywords or topics may not be included in the response.

The RAG process works best when key evidence is found in a few focused documents. Results are less accurate if answers depend on scattered or unclear information.

Language support

aiR Assist currently supports English-language content only. The system has been designed and tested exclusively on English-language datasets to ensure accuracy, reliability, and consistent performance.

At this time, non-English languages are not supported, and aiR Assist has not been formally evaluated or validated for use with multilingual or non-English text. While it may operate with non-English datasets, results can vary in accuracy and completeness, and verification of cited sources is strongly recommended when working with such content.

Future updates may expand language capabilities based on performance testing and model availability.

Supported use cases

Here are some example questions targeting common use cases for aiR Assist:

Use case	Common category	Example question
Early Case Insight	Finding potentially important documents	Can you find me documents that discuss potential gifts or incentives?
	Finding documents by theme	Are there any documents mentioning fraudulent behavior of John Doe?
	Understanding actors and roles	Who was involved in discussions about offering gifts?
Case Strategy Development	Identifying a series of events	Create a high-level timeline for events that took place before the start of Project Artemis.
	Understanding communications and relationships between actors	Who communicated with whom about the contract terms?
Deposition/Trial Preparation	Suggesting exhibits based on key criteria	List documents to use as exhibits based on [key document criteria].
	Confirming conversations or actions took place	Did John Maxwell send an email about the compliance policy?
