This is an advanced feature requiring explicit config. It is not enabled by default.
Agent Memory is an experimental feature that allows your assistant to persist data about users across conversations. This enables experiences like repeat-caller logic, customer preferences, and cross-channel continuity. It uses a key-value store attached to a user identifier (like phone number). Memory is read at the start of each turn and written after the conversation ends. You can:
  • Read memory using conv.memory.get("key")
  • Write memory by setting conv.state["key"] = value (if configured via state_keys)

​
Configuration

​
JSON config (Agent Studio)

To enable Agent Memory: 
{
  "memory": {
    "repeat_caller": {
      "analytics_enabled": true,
      "state_keys": ["booking_day", "cheese_type"],
      "identifier_blacklist": ["+447777"]
    }
  }
}
  • analytics_enabled: Adds repeat caller metrics to Studio analytics
  • state_keys: Keys to save from conv.state to memory
  • identifier_blacklist: Optional list of excluded IDs (e.g. test numbers)

​
Using memory in functions

​
Read memory

def start_function(conv: Conversation):
    cheese = conv.memory.get("cheese_type")
    if cheese:
        conv.say(f"You previously picked {cheese}.")

​
Write memory (via conv.state)

def book(conv: Conversation):
  conv.state["cheese_type"] = "brie"
These fields will only be persisted if they are listed under state_keys in your config.

​
Example: conditional reuse

def start_function(conv: Conversation):
  booking_day = conv.memory.get("booking_day")
  cheese_type = conv.memory.get("cheese_type")
  if booking_day and cheese_type:
    conv.say(f"You booked {cheese_type} for {booking_day}. Rebook?")

​
Memory behaviour

  • Memory is read once per turn and cached.
  • Memory is persisted at the end of a conversation.
  • Only supported identifier today: phone number.

​
FAQ

​
Can I store nested JSON?

No. Each value must be a string, number, or flat serializable object. Always avoid packing PII into a single field.

​
Can I check if memory exists?

Yes: 
if "booking_day" in conv.memory:

​
Can I prevent overwrites?

Not directly, but you can check before writing: 
if "cheese_type" not in conv.memory:
  conv.state["cheese_type"] = value
