Memories are pieces of information that the persona learns during a conversation. Once learned, these memories can be referenced and used by the persona during subsequent conversations. Developers are able to organize memories within memory_stores - a flexible tag-based system to track memories across conversations and participants into different buckets. If a memory_stores value is provided in the conversation creation request, memories will automatically be created and associated to the tag provided.

​
Basic Example

For example, if a participant named Anna starts a conversation with the persona, Charlie, we can specify memory_stores=["anna_charlie"] in the conversation creation request. By doing so, Charlie will:
  • Remember what was mentioned in a conversation and form new memories with Anna.
  • Reference memories from previous conversations that Charlie had with Anna in new conversations.
Example conversation creation request body: 
{
  "persona_id": "your_persona_id",
  "replica_id": "your_replica_id",
  "memory_stores": ["anna_charlie"]
}

​
Managing Memories Between Participants and Conversations

To prevent different personas from mixing up information for the same participant, we generally recommend you to create separate memory_stores values for each user when they talk to different personas.For example,
  • When Anna talks to Charlie, you can use the memory_stores value of ["anna-charlie"].
  • when she talks with Gloria, you can use the memory_stores value of ["anna-gloria"].
The memory_stores system can be used flexibly to cover your use cases - they do not have to map 1:1 with your participants and instead can be designed for your unique use cases. For example,
  • If you were setting up an online classroom, you could use a memory_stores tag value of "classroom-1" so any participant of this group could reference and create new memories to enhance and deepen learning and connections.
  • You can control whether you want personas to share memory or not by passing them different memory_stores values.
