Step 01
Profile memory
Stable facts such as names, preferences and backstory are the simplest layer. Useful, but not evidence that the companion recalls events naturally.
Step 02
Conversation context
A limited context window keeps recent messages in view. When it fills, older details may drop unless the product summarizes or retrieves them.
Step 03
Durable recall
The convincing version retrieves relevant earlier moments without being reminded. Test it across days and unrelated topics, not five consecutive messages.
- Plant a harmless specific detail
- Change topics
- Return later
- Check whether recall is accurate rather than merely agreeable
The practical next move
A guide becomes useful when it changes a decision. Choose one small test, record what happened, and compare the result with the product’s promise. Do not reward a vague answer with a longer subscription.
