- "Mixed feedback—praised for ease and reporting but dinged for outdated look/feel, limited dropdown/admin controls" (Grok 4.20, Virtual data rooms)
- "No native AI capabilities, dated reporting layer, opaque quote-based pricing, still somewhat expensive" (Kimi K2, Virtual data rooms)
- "Reviewers often cite "tricky settings" and a "clunky Q&A tracker."" (GLM 4.7 FlashX, Virtual data rooms)
