LegalOn helps legal teams review contracts faster. A lawyer opens a draft in Word, and the tool checks it against a review checklist, highlighting risky or missing clauses and suggesting alternative wording. The checklists are built by lawyers, which the company says makes the guidance reliable.

Beyond review, the platform offers features for contract creation and management, and AI that answers questions about legal matters and compares language across documents. It started in Japan under the name LegalForce, where it grew quickly, and has expanded into North America and Europe.

LegalOn is sold to in-house legal teams and law firms on subscription. Lawyers must still decide what advice to follow. Alternatives include Ivo, Spellbook, Luminance, Ironclad, and Harvey. LegalOn suits legal teams reviewing many contracts.
