A tie on this record: the two 90% bands overlap, so read the tasks and complaints below.

102 voices on Legora and 10 on Luminance, 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. Legora is a legal AI assistant; Luminance is a contract review tool.

Why this pair: Luminance has only just passed 10 voices on record. Legora is the rival with the most Google impressions for queries naming both tools on our own aivortex.io pages (Search Console record). That record is small and is not search volume.
