7 Best AI Litigation Support Software Tools

What Is AI Litigation Support Software?

AI litigation support software generally refers to technology that helps legal professionals work through time-consuming case tasks with less manual effort.

For example, it uses legal AI to process case information, organize materials, and surface useful details that could otherwise take hours to find.

Essentially, the software gives law firms a faster way to work with large amounts of case data. Depending on the platform, it may support parts of the litigation process such as discovery, document review, or legal research.

The information is then presented in a clearer format, which can make it easier to understand what is relevant and decide what needs attention next.

From there, legal AI tools can help create a more consistent workflow as a case develops. Your team may spend less time searching through disconnected files, repeating routine work, or manually sorting new information as it comes in.

Generally, the best platform is one that fits naturally into the way your firm already handles litigation. It should make case materials easier to review and use without adding unnecessary steps to the process.

What Difference Does AI Make?

AI mainly changes how quickly your team can work through large amounts of case information. It can also make repetitive legal work easier to manage as a case grows.

Here are a few of the biggest differences:

• Faster document review: AI-powered platforms can process tens of thousands of pages and surface relevant material much sooner than a manual review.
• More focused legal work: Legal AI can organize case information and highlight useful connections, which gives your team more time to examine the issues that need closer attention.
• Better legal context: Legal-specific AI models generally understand legal language and workflows more clearly than general-purpose AI tools.
• Greater consistency: AI can apply the same review criteria throughout a large document collection, which helps reduce variation during repetitive work.
• More capable automation: Agentic AI can handle connected parts of a workflow with less step-by-step input and prepare material for the next stage of review.

General AI tools may still help with basic summaries or drafting, but litigation software usually gives you stronger legal context and features built for active casework.

7 Top Software Options for AI Litigation Support

Your choice will depend on the type of casework you want the software to handle and how well it fits your existing tech stack.

Here are seven options that take different approaches to litigation support, which should make the comparison easier:

1. Briefpoint

Briefpoint is an AI litigation support platform built specifically for written discovery. It helps lawyers prepare a solid first draft of discovery requests and responses without spending hours copying language between files, formatting legal documents, or rebuilding prior work for each case.

The process starts with your existing case documents. Briefpoint reviews the uploaded material, identifies relevant facts, and generates draft responses that reflect the applicable court rules.

Your team can then refine the language and export the completed work to Microsoft Word before serving it on opposing counsel.

Briefpoint also supports the client-facing side of discovery. Client Bridge converts formal questions into plain English and gives clients a secure place to submit answers and files.

For requests for production, Autodoc identifies responsive documents and creates Bates-cited responses with an organized production package.

Because these steps stay connected, firms can reduce the billable hours spent on routine discovery work while keeping the final document drafting process familiar.

Best Features

• AI discovery drafting: Creates interrogatories, requests for admission, and requests for production based on the complaint and case details.
• Discovery responses: Suggests objections and prepares draft responses using your firm’s preferred language.
• Client Bridge: Rewrites questions in plain English and sends clients a secure link where they can provide answers or upload files from any device.
• Autodoc: Finds documents responsive to each RFP and generates Bates-cited Word responses alongside an organized production package.
• Jurisdictional support: Applies local formatting rules and supports discovery work in state and federal courts throughout the United States.

Pros

• Focuses closely on the written discovery workflow
• Produces editable Microsoft Word documents
• Reduces the time spent preparing and formatting legal documents
• Connects client collection directly to discovery responses
