Cons
- ✗Complete pricing opacity for both tiers creates impossible budget planning and evaluation barriers for cost-conscious organizations
- ✗Gap between no-code visual editor and SDK deployment requirements means non-developers cannot ship experiences independently

- ✗Small user community and limited third-party ecosystem compared to mainstream conversational AI platforms reduces available integrations
- ✗Learning curve extends beyond technical requirements to include narrative design, character development, and conversation optimization skills
- ✗Enterprise tier requires significant upfront development investment before ongoing platform subscription costs
- ✗No meaningful free tier or trial access limits evaluation opportunities before sales engagement and financial commitment
- ✗Relatively new platform with fewer proven long-term case studies compared to established enterprise software solutions

Cons
