99 voices Medium
A tie on this record: the two 90% bands overlap, so read the tasks and complaints below.
872 voices on Claude and 99 on Spellbook, 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; Spellbook is a contract drafting tool.
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.

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.
