Model selection: Limited to OpenAI (GPT-5.1 and 4 series) and Anthropic (Claude, opus and sonnet 4.5) - no support for other LLM providers (Cohere, AI21, open-source models)
Pricing at scale: Flat-rate pricing may become expensive for very high-volume use cases (millions of queries/month) compared to pay-per-use models
Customization limits: While highly configurable, some advanced RAG techniques (custom reranking, hybrid search strategies) may not be exposed
Language support: Supports 90+ languages but performance may vary for less common languages or specialized domains
Real-time data: Knowledge bases require re-indexing for updates - not ideal for real-time data requirements (stock prices, live inventory)
Enterprise features: Some advanced features (custom SSO, token authentication) only available on Enterprise plan with custom pricing

Additional Considerations
Human Handoff Excellence (Core Differentiator): Sophisticated routing rivals dedicated customer service platforms - round-robin assignment (skipping offline agents), channel-based routing, geographical routing, language-based routing, reassignment automation, programmatic assignment (KM_ASSIGN_TO parameter) vs basic handoff from typical RAG chatbots
Handoff Features
100+ Language Translation (Differentiator): Unique capability - bots trained on single-language documents respond in user's preferred language WITHOUT translated content. Upload English documentation once, serve 100+ languages automatically. Dynamic switching via updateUserLanguage() - rare among RAG competitors
Comprehensive Mobile SDK Ecosystem (Differentiator): 6 official SDKs (Web/JavaScript, Android, iOS, React Native, Flutter, Capacitor/Cordova) - strongest mobile coverage. Native integration vs external chat widgets for better UX in mobile app customer support. BlueStacks validation: 4.3M+ messages demonstrating production-grade reliability
AI Insights Natural Language Analytics (Differentiator): "Ask any question about conversations across platforms" - natural language analytics querying. Choose between Zendesk tickets or conversation history for analysis scope. No SQL required - business users query without database knowledge. Cross-platform insights (WhatsApp, Instagram, Facebook Messenger, website, Telegram unified)
15,000+ Customer Validation: Wide deployment with named customers (BlueStacks 4.3M+ messages, Epic Sports 60% containment, GAP Chile, HDFC) - Google AI First Accelerator 2024 selection indicates innovation recognition
Accessible SMB Pricing: $40/month Starter vs $700+/month enterprise-only competitors (Progress, Drift) - 17x cheaper entry point. Conversation-based model (~40 messages per conversation) different from per-query pricing
Rapid Deployment: "In a minute or less" training with website scraper, 30-day free trial with no credit card required, quick start workflow (Sign up → Bot Integration → create with Kompose → train → copy snippet → go live)
NOT a RAG-as-a-Service Platform: CUSTOMER SERVICE AUTOMATION PLATFORM with RAG-like capabilities - NOT pure RAG-as-a-Service infrastructure. Architectural focus: Conversational AI layer with RAG features vs RAG-first platform like CustomGPT or Cohere
Platform Type
Developer Limitations: NO programmatic knowledge base API (dashboard UI only), NO Python/Node.js server-side SDKs (REST API only), NO cloud storage integrations (Google Drive/Dropbox/Notion absent) - limits developer workflows
Cloud Storage Gap: NO Google Drive/Dropbox/Notion vs competitors with native cloud document workflows - critical for knowledge-centric teams with cloud-first processes
Microsoft Teams Absent: NO Teams integration while WhatsApp, Slack, Telegram, Instagram supported - B2B enterprise messaging gap for Teams-standardized organizations
Comparison Validity: Architectural comparison to CustomGPT.ai is LIMITED - fundamentally different priorities (customer service automation vs RAG infrastructure).
