How AI Companions Learn Your Preferences Over Time

It's not magic. Here's the actual mechanism — and why it means the relationship compounds.

The question people most often ask before committing to an AI companion is: does it actually remember what I tell it? The answer, for SAM, is yes — but it's worth understanding how, because the mechanism shapes everything about how the relationship develops. Memory isn't a single thing. SAM uses three overlapping layers: in-session context, Heartline (emotional and episodic memories), and SAM Memory+ (long-term patterns). Each works differently, and together they explain why the relationship feels increasingly personal the longer you use it.

Key features

  • Short-term: in-session context — Everything you say in a single conversation is in the companion's immediate context window. It can refer back to something you said earlier in the same session without any special retrieval.
  • Medium-term: Heartline — Emotionally or episodically significant moments — a piece of news, a relationship you mentioned, a recurring theme — are saved to Heartline. These persist across sessions and are retrieved when relevant. You can view and delete them from settings.
  • Long-term: SAM Memory+ patterns — Over weeks, SAM builds a pattern layer — the recurring themes, preferences, and through-lines of your conversations. This is what makes a six-month companion feel like it really knows you, not just remembers facts.

Frequently asked questions

How do AI companions learn your preferences over time?
Through three layers: session context (everything in the current conversation), Heartline (emotionally significant moments saved across sessions), and SAM Memory+ (long-term patterns extracted from months of conversation). The more consistently you use it, the richer each layer becomes.
Do AI companions actually remember what you tell them?
SAM does — across sessions, not just within them. When you mention something significant, it's stored in Heartline and available for future conversations. Long-term patterns accumulate in SAM Memory+. What SAM remembers isn't a transcript of everything — it's the meaningful parts, retained and retrievable.
What features should your AI companion have in terms of memory?
Cross-session memory (not just in-conversation), a way to view and delete what it knows about you, and intelligent retrieval — not dumping everything it remembers into every reply, but surfacing the right context when it's genuinely relevant.
Can you use the same AI companion across multiple devices?
Yes. SAM is cloud-based — your companion, conversation history, and memory are all account-tied and available on any device where you're logged in. There's no device-specific state.
How long does an AI companion remember?
On SAM, indefinitely — or until you delete it. Soul tier has the deepest recall horizon. Heartline entries persist until you remove them. SAM Memory+ patterns accumulate for as long as the account is active. There is no automatic forgetting.
