Types of AI contract review tools
Word add-ins for redlining
LexCheck, Spellbook and LegalOn run inside Microsoft Word, comparing a draft to a playbook and inserting redlines directly into the file. They suit lawyers who negotiate other parties' paper, want to stay in one document, and prefer to keep their existing review habits and approval chain unchanged.
Agentic legal workspaces
Legartis and Harvey describe agents that carry out several steps in sequence and escalate whatever falls outside the written rules. Buyers define thresholds for what passes automatically and what a named person must approve, so the agent works within limits that legal sets.
Contracting platforms with AI
Juro and Ironclad put AI review next to templates, workflows, signature and a searchable repository of signed agreements. They fit companies where business users create the contracts themselves and the legal team sets the guardrails and approvals for everyone else.
Due diligence and portfolio analysis
Kira and Luminance extract terms across very large sets of documents. They serve M&A teams and large enterprises that need answers across a whole contract portfolio or data room rather than a single redline on one agreement, and they expect a longer rollout.
