US court opinions, dockets, judges and citations.
CourtListener is the Free Law Project’s legal research site, a nonprofit archive of millions of US court opinions, PACER dockets, judge profiles and oral arguments. Connected to a workspace, GBrain can answer “has the Ninth Circuit ruled on this question since 2020?” or check every citation in a draft brief against the record.
It can also set and remove alerts, so a team hears when a docket it follows moves.
GBrain gives CourtListener a command line too. From a terminal, a
script or Claude Code,
gbrainio tool help courtlistener
lists its commands once it is connected.
