AI Companions Could Soon Remember Your Past Chats
Imagine an AI friend that recalls your favorite things—here's what that means for privacy.
Memory can sustain AI companionship, yet even accurate recollection can be inappropriate to use. Two rounds of formative interviews with 14 users (n = 6 exploratory, n = 8 memory-focused) motivate asking what a companion should consider before using past information.
Eight themes inform Reconsider, a single-call procedure with five checks and four handling modes, evaluated on 80 scenarios across five models over 400 blinded within-model pairs. Two LLM judges favored Reconsider by net margins of +15 and +23 percentage points, with bootstrap intervals excluding zero for three of five models but not for GPT or Claude.
Evaluator analysis linked judge scoring differences to model family, and a preliminary matched-guidance control isolating memory-specific content gave positive margins. We contribute an interview-grounded design framework for memory use and an evaluation that scrutinizes its own evaluators.
- AI companions may soon remember your past conversations to make chats more personal.
- But storing your info raises privacy risks if not handled securely.
- Researchers suggest giving users control over what the AI remembers.
Why It Matters
Your AI chats could become more personal, but your private info might be stored—so demand control.
