The 8 Best AI Tools for Legal Writing & Drafting in 2025

In 2025, attorneys are embracing AI tools not as shortcuts but as essential assistants that bring speed, accuracy, and consistency to drafting, editing, and summarizing legal documents. Whether you're running a solo practice or leading a mid-sized firm, the right AI can dramatically improve your workflow—and your bottom line.

This guide will walk you through the best AI for legal writing—from drafting contracts to refining briefs and translating correspondence. These tools are helping lawyers work smarter, write better, and focus more on practicing law, not formatting documents.

Why Lawyers Are Turning to AI for Legal Writing

Drafting legal documents is one of the most time-intensive parts of legal work. Whether it’s contracts, memos, or briefs, legal professionals face mounting pressure to write accurately, quickly, and in a tone that instills trust. AI is helping reduce the risk of human error, save billable hours, and standardize workflows.

According to the 2025 Legal Industry Report, 54% of legal professionals now use AI for drafting correspondence, making it the most common legal use case. Others include summarizing documents (39%), editing (35%), and drafting legal templates (32%).

As AI adoption grows, lawyers are becoming more discerning about which tools they use. The next step is knowing what features to look for in the best AI for writing legal documents.

What to Look for in Legal Writing AI Tools

To truly meet the demands of legal practice, the most effective AI writing tools go beyond general intelligence—they’re purpose-built for law, with features that align closely with the profession’s unique standards and responsibilities. Look for tools that:

• Are trained in legal-specific work 

• Understand citation norms

• Ensure confidentiality

• Respect jurisdictional nuances

• Integrate smoothly into your existing workflows

While general-purpose tools like ChatGPT or Claude AI offer powerful capabilities, they lack legal-specific guardrails. Legal writing demands tools that protect confidentiality, understand precedent, and support ethical obligations.

AI is quickly becoming a core part of how legal professionals draft and refine their work. Below, we’ve outlined eight top tools—each designed to solve a specific legal writing challenge and help attorneys save time without sacrificing accuracy.
