Fin is a new AI agent released by Intercom, designed to answer customer questions and provide support. It uses GPT-4 models to understand customer queries, search for relevant content in help centers, and provide accurate answers. Fin can be powered by content from Intercom Articles, Zendesk Help Center, or any public URL. It can handle multiple external content sources simultaneously and is expected to improve over time. The system has features like Custom Answers, Inbox view, and performance reporting. However, it also raises concerns about privacy, security, and compliance, as customer conversations are processed through OpenAI, a US-based company. Fin's pricing will be per resolution, and customers can set resolution limits within the product. It is expected to be available for free during the beta phase, with future pricing details to be shared soon. The system is still evolving rapidly, and its capabilities and limitations are being actively explored.
