LegalOn
Playbook-guided contract review in Word, plus vault and intake for in-house teams.
Tokyo, Japan and San Francisco, California
- What it does
- LegalOn is in-house contract AI from a Tokyo-founded company that now sells into US legal teams. Review scores counterparty paper against attorney-built playbooks (vendor lists 50-plus stock playbooks, plus custom My Playbooks) and writes redlines in Microsoft Word or the browser. Assistant answers questions on the open contract, drafts fallback language, and summarises terms. Matter Management takes requests from email, Slack, or forms into tracked work. Vault stores signed agreements and extracts dates and obligations; the vendor positions it as lighter than a multi-quarter CLM program. Translation covers 28-plus languages. Entity and Board modules sit beside the contract stack. Agents return structured outputs for attorney review. Pricing is demo-quoted (confirm with LegalOn). It is not Westlaw or Lexis research, not e-discovery, not practice management, and not a published-seat Word add-in. You still review the redlines.
- Fit
- In-house legal, legal ops, procurement, and contract managers who review repeating NDAs, MSAs, and vendor paper in Word and want stock or custom playbooks without standing up Salesforce-class CLM.
- Not a fit
- Plaintiff PI, litigation files, or anyone who needs Clio write-back and case-law research. Skip if you need DocuSign, Salesforce, or Coupa lifecycle routing — LegalOn names Word, Slack, and email, not a CRM CLM bus. Demo-only pricing. Owner-led shops without a review desk should not treat agent output as a substitute for a lawyer; the vendor is not a law firm.
- Audience / pricing
