"How Hindsight Lets a Support Chat Continue Across Sessions"
A support assistant that remembers a customer’s laptop model but forgets which conversation contained it is only halfway useful. I built RecallCare around a different boundary: conversation history belongs to a thread, while customer knowledge should follow the customer. That sounds like a storage choice. In practice, it changes retrieval, prompting, failure handling, and even what I show in the…
RecallCare is an AI-powered support chat application designed to provide customer assistance across multiple conversations. Instead of treating a customer's support history as part of every conversation prompt, RecallCare separates conversation history and customer knowledge into two distinct contexts.
The frontend is built with React, featuring a dashboard and conversation view, while the backend is constructed using FastAPI. SQLAlchemy persists customer, conversation, and message data, while authentication handles customer identification. An LLM generates support replies, and Hindsight is responsible for retaining and recalling customer information across threads.
When a customer initiates a new support request, the application retrieves relevant memories from Hindsight based on the customer's ID and the context of the current conversation. Hindsight's memory bank identifier is a stable, SHA-256 derived string that allows the system to connect customer memories across sessions without loading the entire conversation history.
During conversation retrieval, Hindsight is prompted with both recent messages from the selected conversation and relevant customer memories. The recent messages are labeled as "CURRENT CONVERSATION CONTEXT" and are kept separate from the customer memories, which are labeled as "LONG-TERM CUSTOMER MEMORY." This separation allows the AI to prioritize and utilize the most appropriate information for generating a response.
In the event of recall failures, the chat endpoint gracefully handles the situation by providing a helpful fallback message, ensuring a smooth user experience. RecallCare demonstrates the importance of separating long-term customer memory from current conversation context, resulting in a more efficient and effective support chat application.
