❓ FAQ

Q: Why not use only Rasa?

A: Our LangGraph agents are production-ready with advanced RAG, reranking, and tool integration. We use Rasa for intent/dialogue and LangGraph for orchestration.

Q: Why not build from scratch?

A: We'd spend 3-4x more time and money. Open-source libraries are battle-tested and integrate well.

Q: What's the learning curve?

A: ~3-4 weeks for team proficiency. Rasa is the steepest, but worth it.

Q: Can we customize the UI?

A: Yes! Use Chainlit for quick deployment, or build custom React UI for full control.

Q: What about data privacy?

A: Rasa and Chainlit can run self-hosted. Use local Whisper for privacy-critical voice.
