Long-term memory (in AI partners)
An AI partner's ability to recall facts and context from prior conversations across days, weeks, and months.
Long-term memory in AI partners is what makes a relationship feel like a relationship. Without it, every conversation starts over. Implementations vary: simple retrieval, vector search over conversation history, hierarchical summarization, structured fact stores. We rate every platform on memory consistency at 1 day, 7 days, and 30 days into a relationship.
