## The case on Intercom

Build a scaled-down single-user helpdesk and RAG chat widget subset, but keep paying for Intercom if you need robust omnichannel routing and production reliability.

Hardest parts:

- Sub-second real-time state synchronization across live widgets and agent dashboards
- Deterministic RAG orchestration with citation tracking and tool execution for Fin
- Ultra-lightweight script bundling for host website injection with zero CSS leakage
- Handling concurrent conversation handoffs between automated AI and human agents

## The case on Zendesk

Build a focused subset with core ticketing, a knowledge base, and an AI copilot, but expect a multi-week grind handling email ingestion webhooks and real-time state sync.

Hardest parts:

- Bi-directional email parsing and reliable IMAP/SMTP webhook loops without dropping inbound attachments or threading replies
- Real-time multi-agent concurrency synchronization for ticket status updates and typing indicators
- Zero-latency RAG vector embedding pipeline for knowledge base retrieval backing autonomous AI agents
- Complex automation engine executing conditional triggers and time-based SLAs in background workers without race conditions
