LegalOn
LegalOn is a contract lifecycle platform from LegalOn Technologies, Inc. covering intake, review, redlining, storage and analysis, built on more than 135 attorney-authored playbooks across industries and countries, with a Microsoft Word integration and agentic workflows.
- Review standards trace to written attorney playbooks rather than to statistical patterns
- Working inside Word removes the behaviour change that kills legal software adoption
- Redlines as tracked changes are immediately sendable rather than a task to perform
- Intake from email and Slack captures work that otherwise enters no system
- Playbook coverage is uneven by definition, and the gap between covered and uncovered is large
- Which jurisdictions are covered, and how current the playbooks are, is not published
- The underlying models are not disclosed
Spellbook
Spellbook reviews and drafts contracts inside Word and Google Docs, redlining against a firm's own playbooks, comparing terms to thousands of similar agreements, and indexing signed contracts for search — used by a stated 5,000-plus legal teams in 80-plus countries.
- Runs inside the tools lawyers already use rather than beside them
- Playbooks encode institutional memory rather than generic best practice
- Zero retention named at provider level, where the uncertainty usually sits
- Compliance set includes the EU AI Act, which few vendors list yet
- Output quality tracks playbook effort, which teams routinely underestimate
- Market standard data can erode a negotiating position if used as an argument
- Bespoke or novel agreements remain outside what a first pass helps with
