What Is Intercom Fin and How Does Its AI Work?
Intercom is a customer messaging platform that pioneered the in-app chat widget and evolved into a comprehensive support and engagement suite. Its AI product, Fin, launched in 2023 and is built on large language models (initially GPT-4, now a hybrid model). Fin answers customer questions conversationally, drawing on your Intercom articles and, with configuration, external content sources.
Fin is a genuinely capable AI assistant. It handles multi-turn conversations, understands context, and can be customized with topic restrictions and escalation rules. The challenge is not the technology — it is the pricing model and the depth of RAG grounding.
The Per-Resolution Billing Problem
Intercom charges $0.99 per AI resolution — defined as a conversation Fin closes without a human taking over. For teams handling 2,000 conversations per month with a 70% AI resolution rate, that is 1,400 resolutions × $0.99 = $1,386/mo in Fin charges alone, before the base Intercom seat subscription. UnifiedRAG includes unlimited AI resolutions on all plans. The $49/mo starting price does not change as your volume grows.
How Intercom Defines an 'AI Resolution'
Intercom's billing counts a resolution when a customer marks the conversation as resolved or closes the chat after Fin responds, without requesting human help. This definition can be gamed (some customers close without really being satisfied) or disputed (customers who abandon without marking resolved may not be counted). UnifiedRAG's analytics tracks confirmed resolutions, deflection rates, and confidence scores — giving a cleaner picture of actual AI effectiveness.
