Weaknesses

- Con: Case law coverage is narrower than Westlaw and LexisNexis, with reviewers noting it works less well for older and more historical decisions.
- Con: Its library of secondary sources and treatises is thinner than the premium platforms, so many practitioners still need Westlaw or Lexis for analytical and how-to materials.
- Con: Reviewers describe the interface as clunky and slow, and the newer vLex and Vincent AI tools carry a moderate learning curve before they feel natural.
