Structuring long conversation histories as timestamped events with intelligent retrieval guidance lets AI agents accurately answer complex questions about what happened weeks or months ago—critical for building chatbots that remember user preferences and history over extended periods.
Chronos is a memory system for AI chatbots that tracks conversations over months by breaking down dialogue into timestamped events and organizing them in structured calendars. When answering questions about past conversations, it uses dynamic prompts to guide retrieval across time ranges and handle complex multi-step reasoning, achieving 95.6% accuracy on long-term memory tasks.
