Claude vs CoCounsel: what lawyers say.

Claude ahead on this record: the two 90% bands do not overlap.
872 voices on Claude and 411 on CoCounsel, 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. Claude is a general-purpose model by Anthropic; CoCounsel is a legal AI assistant 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.

Claude has the higher net (+37 against +2) and the two 90% bands do not overlap. That describes who posts and how they feel, not which product is better. Difference in net: +35 points (Claude minus CoCounsel).

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.
