our call

Start with Kayako — highest vibe code, weakest moat.

Intercom

You can build a clean React shared inbox with an AI auto-responder in a couple of weeks using modern LLM APIs and pgvector. However, replacing Intercom entirely requires maintaining complex email parsing, SMS gateways, WhatsApp APIs, and carrier-grade deliverability.

you can rebuild

  • Embedded live chat storefront widget and shadow DOM wrapper
  • RAG-based AI support auto-responder for routine customer inquiries
  • Basic shared inbox for agent triage, tagging, and assignment
  • AI agent assistant for drafting customer responses inside the inbox
  • Knowledge base article hosting and searching

what you lose

  • Fin's turnkey resolution guarantee and multi-million conversation evaluation safety harness.
  • Native integrations with thousands of SaaS applications and Shopify app store extensions.
  • Proactive outbound messaging features (In-app tours, push notifications, carousels, and series builders).
  • Enterprise compliance features including HIPAA support, SSO, and global SLA enforcement.
  • Turnkey multi-channel delivery (Email, SMS, WhatsApp, Phone) managed under a single unified billing model.

real moats

  • Deep app store ecosystem integrations with two-way sync into major e-commerce platforms.
  • Proprietary multi-turn AI resolution benchmark datasets collected from millions of historical conversations.

  • Shopify customer data sidebar displaying recent orders and tracking
  • Tagging, macros, and templated canned responses

  • Turnkey native iOS and Android agent apps
  • Built-in web embeddable live chat widget with cross-domain session persistence
