New buyers should look at active alternatives such as LexCheck, Spellbook or Ironclad); Ironclad (best for: Mid-market and enterprise in-house legal teams with many contract types across sales, procurement and HR); LexCheck (best for: In-house teams and firms reviewing high volumes of a few recurring contract types against a stable playbook); Luminance (best for: Large law firms and corporate legal departments with high contract volume across business teams); Legora (best for: Mid-size and large firms and in-house teams with heavy review, drafting and multi-jurisdiction work); LegalOn (best for: Solo transactional attorneys, fractional GCs and in-house teams reviewing commercial contracts).
