What Could Be Better
  • Confusing Credit System - 'Unlimited' plan reported to have hidden limitations with Elite Credits-users cite pricing transparency concerns and credit confusion.
  • Very Limited Free Tier - Only 30 basic model queries per day with no access to advanced models (GPT-4o, Claude, o1)-insufficient for serious evaluation.
  • Performance Issues with Multiple Models - Running multiple AI models simultaneously causes high CPU/memory usage-not suitable for low-spec devices.
  • Steep Learning Curve - Extensive feature set (sidebar, agents, Wisebase, Web Creator, REC Notes) overwhelming for new users-requires time investment.
  • No Enterprise Reviews - No G2/Capterra ratings make it difficult to assess enterprise reliability-mixed Trustpilot reviews (2.7/5 from 7 reviews) raise concerns.
