AI Repository just launched this week! Try out the new features.
Legal writing has always been time-consuming, detail-heavy, and repetitive. But with the help of artificial intelligence, that’s finally starting to change.
From contract drafting and court filings to legal research, policy writing, and memos, AI tools are helping legal teams speed up their work without giving up quality.
These tools aren't just for tech-savvy firms. They're built to support real legal workflows, whether you're in a solo practice or part of a large legal department.
In this guide, you'll find the best AI tools for every major legal writing task. We’ll cover what each category of tool does, how it helps with legal work, the best use cases, and our top pick in each area.
Let’s break it down, starting with the contract work that eats up the most time for lawyers.
Contract work eats up more time than most lawyers care to admit. It’s tedious, repetitive, and if you miss a single clause, things can go sideways fast.
Legal AI tools now play a real role in solving that. For drafting, reviewing, and redlining contracts, they help cut through the busywork and reduce the back-and-forth.
AI for contract drafting and review is changing how the legal profession handles everyday legal tasks. These tools help legal teams write, edit, and review contracts in less time and with fewer mistakes.
Here’s how it works: the AI is trained on thousands of real contracts and legal documents, so it knows what to look for. That includes missing terms, unusual clauses, or anything that doesn’t match standard legal language.
When a lawyer uploads a contract, the AI reviews it almost instantly, flags risky sections, and suggests edits based on pre-set rules or company playbooks. It can even compare versions, track changes, and generate new drafts from scratch using templates you already use.
Legal teams no longer need to jump between Word, email, e-signature platforms, and shared drives. Everything from drafting to storing happens in one tool.
If you're searching for the best AI for legal writing, especially for contracts, Aline stands out.
Aline isn’t just a typical CLM platform. It’s built for legal professionals who need to handle legal tasks quickly, clearly, and without the chaos of switching between tools. Everything from drafting to signing happens in one place, saving time and cutting down mistakes.
Here’s what makes Aline a smart choice:
It’s a fast, flexible platform designed to help legal teams get more done. If you want to see how it works, start your trial today!
Handling court documents and litigation prep is no small task. Between motions, responses, and filings, it’s easy for legal teams to get buried in the work.
AI can step in here to help lawyers draft faster, manage case details, and keep everything organized without cutting corners.
AI tools built for litigation support assist with writing court-ready documents, summarizing key case materials, and staying on top of deadlines.
Some can draft motions or responses based on past cases. Others scan through transcripts, identify important details, and even help build timelines.
These tools are trained on real legal documents and know how to follow court formatting and language expectations. Instead of manually piecing together filings, legal professionals can use AI to build solid drafts in less time.
Casetext CoCounsel uses advanced legal AI to assist with litigation-related writing and review. Built on GPT-4, it understands legal context and helps generate accurate, clear court documents fast.
You can ask it to draft a motion, summarize a case file, or scan through evidence for key points, and it delivers in minutes.
With CoCounsel, legal teams save hours preparing court materials, especially for repetitive or high-volume tasks. It’s designed to give lawyers more time to think strategically and less time worrying about formatting or starting from scratch.
Key features include:
Research is one of the most time-consuming parts of legal work. Digging through case law, scanning past rulings, and writing legal memos can take hours, sometimes days.
But AI is making this part of the job a lot more manageable, mainly for law firms that deal with complex or high-volume matters.
AI software for legal research uses natural language processing to understand legal questions and pull relevant case law, statutes, or summaries. Instead of sifting through endless results, you can ask direct questions and get precise, cited answers.
These tools are trained on massive databases of legal material, which helps them understand context and terminology in a way that works for real legal practice.
Some of these tools also help you write memos, create summaries, and draft research-backed arguments. Whether you're responding to opposing counsel or building your case from scratch, an AI legal assistant tool can take on the first draft or handle the heavy lifting.
Lexis+ AI brings together the depth of the LexisNexis database with smart AI features built for the legal profession.
It uses advanced natural language processing to understand what you’re asking, even if it’s not written like a textbook, and returns case law, statutes, and practical answers that are easy to apply.
You can search by question, get cited results instantly, and even generate outlines or memos that speed up early-stage legal writing.
Why Lexis+ AI stands out:
Creating clear and accurate policies is a must in the legal environment. Whether it’s for internal use, client compliance, or regulatory reporting, legal departments are constantly writing and updating documents to reflect new rules and responsibilities.
The problem? It’s slow, repetitive, and often involves piecing together scattered templates and references.
AI legal tools built for compliance and policy work help legal teams draft, review, and maintain documentation with far less effort.
These tools rely on large language models trained on regulatory texts, legal guidelines, and past documents. They understand how to structure a legal brief, follow legal principles, and flag areas that need updates or clarification.
You can ask them to generate a policy based on new regulations, revise an old one, or review a set of documents for consistency. Some tools even handle version control, role-based approvals, and audit logs in one place.
By speeding up legal document review, these tools allow legal departments to focus on higher-value tasks while staying in line with local and international rules.
ClauseBase is a flexible, AI-powered document automation platform that’s ideal for compliance-heavy work. It helps legal departments create structured documents that can be quickly adapted as laws or company rules change.
Built with the legal field in mind, ClauseBase uses intelligent clause libraries and customizable logic to generate policies, contracts, and formal statements with ease.
It supports legal document review, ties in your existing legal data, and keeps everything aligned with core legal principles.
Here's why ClauseBase works for compliance:
Writing the same type of document over and over again? Most legal teams are.
Whether it’s contracts, letters, or internal notices, a lot of time goes into repeating the same formatting, structure, and language. That’s where legal AI software built for automation and templates really shines.
These tools are designed to simplify legal document creation by using smart templates and generative AI tools.
You create a template once, let’s say for a service agreement, and the software fills in the details for you based on a short prompt or questionnaire. Some tools can even handle variations, like different terms for different regions or business units.
Modern AI models understand legal language and can help write full drafts of lengthy documents like contracts, memos, or even policies. They also integrate with tools you already use, like Microsoft Word, so your team doesn’t have to learn a whole new system.
For busy teams handling complex legal tasks, document automation is a huge time-saver. It reduces errors, keeps formatting consistent, and lets lawyers focus on higher-level work, such as writing legal briefs or helping clients conduct legal research.
Gavel is a no-code legal software platform that helps law firms and in-house teams automate documents without relying on developers or IT. It’s built for lawyers, so you can build powerful workflows, connect templates, and use branching logic without touching a line of code.
With Gavel, you can turn your most-used documents into smart, reusable templates. It supports complex inputs, integrates with Microsoft Word, and works with advanced AI models to help draft content inside your templates.
Why legal teams love Gavel:
Even outside of contracts and litigation, lawyers spend a huge chunk of time writing. Emails, memos, legal arguments, letters to clients, and internal notes—it never really stops.
General-purpose AI writing assistants can help lighten the load. They're not limited to one task. Instead, they support a wide range of complex writing needs across the legal workflow.
These tools help lawyers write faster and more clearly without losing their professional tone. Some assist with grammar and structure.
Others go further, suggesting better phrasing for legal reasoning, checking citations, or even helping with brief writing. They also work well for teams juggling a mix of legal contracts, client memos, and other legal documents.
While they don’t replace legal expertise, they do help legal professionals communicate more efficiently. Many tools also plug into document management systems, making it easier to find, edit, and reuse past work.
Some AI assistants, like the one included in Bloomberg Law, also tap into legal data and news to help teams stay updated on regulatory compliance or evolving trends.
BriefCatch is a writing assistant built specifically for legal professionals. It doesn’t just fix grammar but also improves clarity, style, and impact. Whether you're writing memos, legal arguments, or formal legal documents, BriefCatch helps polish your draft in real time.
It works directly in Microsoft Word, making it simple for lawyers to improve their writing without switching platforms. Unlike general grammar tools, BriefCatch focuses on the tone and structure needed in legal writing.
Why BriefCatch works for lawyers:
Legal writing doesn’t need to be slow or painful. From contracts and court filings to policies and research memos, AI is changing how legal teams get work done: faster, cleaner, and with fewer delays.
The right tools deliver more than speed. They help you stay accurate, organized, and focused on the legal work that actually matters.

Yes, you can. Many AI tools support legal professionals' work by helping with structure, tone, and clarity in legal briefs. While they can handle routine tasks like formatting and initial drafting, it's still important for a lawyer to review and finalize the content, especially for complex tasks involving legal reasoning or strategy.
AI can draft many types of legal documents, from NDAs and service agreements to policy memos and internal letters. Tools trained on legal narratives and machine learning can quickly generate drafts based on your inputs or templates. They’re especially helpful for handling time-consuming tasks that don’t require creative legal thinking.
ChatGPT-4, especially when used through platforms that apply legal-specific fine-tuning, is a strong choice for law practices. Some companies build on top of GPT-4 with added legal training, allowing lawyers' AI tools to deliver more reliable results tailored to your jurisdiction or practice area.
Several tools specialize in summarizing legal content, but the best ones are built using machine learning and fine-tuned on legal material. They help legal professionals pull out key terms, deadlines, risks, and clauses. If your firm deals with long documents regularly, AI-powered summarization tools can provide a serious competitive edge by cutting down review time.
