LegiMatch vs vLex / Fastcase
A vLex and Fastcase alternative for fact-based case research
Fastcase merged with vLex in 2023, and Clio completed its acquisition of vLex in November 2025. Its AI assistant, Vincent, offers research questions, 50-state surveys, pleading analysis and global coverage. Fastcase has long been offered to members by many state bars. LegiMatch is narrower: it's built to find US decisions with facts like yours and explain each match.
