For anyone looking to streamline legal operations. A curated selection of AI tools that automate contract review and statutory/case law research, with a breakdown of each tool's features and the benefits of adoption.
Introduction: From Contract Review to Legal Research — AI Is Reshaping the Future of Legal Work
As legal departments face increasing pressure to handle more sophisticated work more efficiently, AI technology is attracting growing attention. In particular, adoption of AI tools for tasks like contract review and legal and case-law research is accelerating. These tools help prevent missed risks and dramatically reduce time spent on manual review, easing the burden on legal professionals.
AI is also enabling standardization of legal operations and reducing reliance on institutional knowledge held by individual staff members, with the potential to raise the overall legal capability of the organization.
This article explains how AI tools are being used in legal work and what the benefits are, with concrete examples.
Contract Review Automation
Reviewing contracts requires specialist knowledge and a significant time investment to prevent missed risks and overlooked clauses. Keeping pace with legislative changes and consistently applying internal review standards demands both accuracy and efficiency simultaneously.
AI-powered contract review tools have emerged in recent years as a compelling solution to these challenges.
Below, we introduce the leading AI contract review tools, covering their features and the benefits they offer.
LegalForce | AI legal tool supporting contract review and contract management
LegalForce is an AI platform that supports risk detection in contracts and streamlines the review process. Just upload a Word or PDF contract and the AI instantly surfaces checkpoints, helping prevent common risk oversights and missing clauses.
A "custom automated review" feature lets you register your organization's own review standards for policy-aligned reviews. English-language contracts are also supported, with a translation function and clause-by-clause bilingual table available for download.
OLGA | AI legal OS for efficient contract review and contract management
OLGA is an AI legal operating system that streamlines contract risk detection and review. The AI automatically identifies risky language, missing critical elements, and overlooked clauses in contracts, preventing lapses in concentration from causing misses.
It can also search for clauses from past contracts and contract review manuals, then instantly compare and check everything from standard clauses to company- or counterparty-specific provisions.
LeCHECK | Cloud-based contract review solution for lean legal teams, with contract management and custom-standards review
LeCHECK is an AI-powered contract review cloud service developed and supervised by lawyers. Simply upload a contract file and the AI automatically flags risky sections, explaining why each section poses a risk and what perspective to use when revising it.

Legal and Case-Law Research Automation
Researching relevant laws and precedents is indispensable in legal work, but extracting the right information from a vast body of material is time-consuming and labor-intensive. In an environment where organizations must respond quickly to legislative changes and new rulings, establishing an efficient and comprehensive research method is critical.
AI-powered legal research tools use natural language processing and proprietary databases to deliver fast, accurate information.
Below we spotlight leading AI legal research tools and describe their capabilities and advantages in detail.
Legal Brain | Supports efficient legal research and improved reliability through its proprietary legal database "LegalGraph"
Legal Brain is a legal-specialist AI agent provided by Bengoshi Dot Com (Lawyers.com Japan). Type a question in natural language and the AI extracts relevant laws, court decisions, and specialist publications, then presents the findings organized around the key legal issues.
Using the proprietary legal database "LegalGraph," it efficiently searches and summarizes a massive body of legal information, dramatically cutting the time needed for legal research while delivering highly reliable results.
Legalscape | Next-generation legal research platform used by more than 20,000 practitioners including Japan's top five law firms
Legalscape is an AI legal research platform that combines proprietary natural language processing technology optimized for law with generative AI.
When a user types a question, the "Watson & Holmes" feature uses AI to extract and summarize relevant legal literature and case law. This makes it easier to research complex legal issues that traditional keyword searches struggle to handle, lightening the workload for legal professionals.
