Short answer. Harvey has net sentiment −21 on 749 public lawyer voices and Westlaw AI has +6 on 268, as of . Westlaw AI is ahead on this record: the two 90% bands do not overlap. Net is like minus dislike as a share of voices.
Westlaw AI ahead on this record: the two 90% bands do not overlap.
749 voices on Harvey and 268 on Westlaw AI, all public posts by lawyers and people who work with them, since 2023. This is how they describe using each tool, not a test of the tools. Harvey is a legal AI assistant by Harvey AI; Westlaw AI is a legal research platform by Thomson Reuters.
Why this pair: both sides have 10+ voices on record, and readers of our other legal pages (aivortex.io) open pages naming both tools often enough to clear our demand floor. That is a proxy for demand, not a count of visits to this site.

Westlaw AI has the higher net (+6 against −21) and the two 90% bands do not overlap. That describes who posts and how they feel, not which product is better. Difference in net: −27 points (Harvey minus Westlaw AI).
Net here is plain like minus dislike as a share of that task’s voices, with no band: a task needs 5+ voices on a side to show one. Tasks with fewer on both sides are left out. A voice has one task, set by our classifier.
