How We Selected and Ranked These Tools

We evaluated Ironclad, Definely, Relativity, Harvey, Lexis+ AI, vLex, Legartis, Luminance, Everlaw, and Reveal using three scored criteria: features, ease of use, and value. Features carries the most weight at 40 percent because the category’s real risk is broken workflow behavior, not just writing quality. Ease of use accounts for 30 percent and value accounts for 30 percent because even strong automation can fail if governance configuration and review setup do not stay manageable.

The editorial ranking also follows criteria-based scoring of the capabilities described for each product, not private benchmark experiments. Ironclad set itself apart by pairing playbook-driven clause guidance that maps negotiation positions into structured review steps and approvals with strong features and a top-level ease profile, and that combination lifted it on the features-heavy criterion while keeping workflow execution feasible for review teams.
