Claude vs Gemini: what lawyers say.

A tie on this record: the two 90% bands overlap, so read the tasks and complaints below.
872 voices on Claude and 134 on Gemini, 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; Gemini is a general-purpose model by Google.
This pair no longer clears the rule we use for comparison pages: too few searches that actually compare the two tools (searches for how to use them together do not count). The page stays so links keep working, but search engines are asked not to index it, and every figure on it is still recomputed from the current record.
