About "LegalForce"

What is LegalForce

LegalForce is an AI contract-review platform provided by LegalOn Technologies, Inc. When you upload a pre-signing contract, the AI automatically detects risks and missing clauses across dozens of contract types, and presents directions for revision, sample clauses, and even clause templates. Developed under attorney supervision, it maintains contract-review quality while greatly reducing legal staff's review time. Advertising the No.1 number of adopters, it is a leading contract-review AI in Japan.

LegalForce is evolving into the company's integrated platform "LegalOn." In 2024 the provider launched "LegalOn (formerly LegalOn Cloud)," a new product that supports legal work as a whole with AI agents, and this is now its flagship. LegalForce (contract review) and LegalForce Cabinet (contract management) continue to be offered, but the official site guides users toward migrating to LegalOn (as of August 2026).

Prevent "oversights" with AI and knowledge

What's scary in contract review is oversights caused by limits of experience and time. When LegalForce reads a contract, the AI flags disadvantageous and missing clauses, and you can consult sample clauses, templates, and clause commentary on the spot. Rather than researching from scratch, staff proceed by checking and judging the points presented.

How LegalForce differs from other AI legal tools

AI legal tools differ in "whether they specialize in contract review" or "support legal work as a whole." LegalForce stands out for being strong at contract review and integrated with attorney-supervised knowledge (templates and sample clauses).

Aspect	LegalForce	LegalForce Cabinet	LegalOn
Main purpose	Pre-signing contract review	Post-signing contract management	Integrated support for legal work as a whole
Core features	Automatic review and templates	Automatic info extraction and deadline management	AI agents and matter management
Positioning	Longstanding flagship product	Complement for contract management	Current flagship

In the same legal domain, Legalscape for case-law and literature research, Legal Brain as foundational legal technology, and LeCHECK for contract review are comparison points. For legal departments that want to balance contract-review quality and efficiency, LegalForce is a standard choice.
