Documentation by criterion
StorageNot publicly established
Storage and scope
Conway describes owned AI for personal devices. Fetching the product domain leads to a sale page; memory storage and format are therefore unestablished.
SelectionNot publicly established
Selection and timing
The accessible vendor source explains no automatic selection or storage of durable memories.
Edit & deleteNot publicly established
Inspect, edit and delete
Inspection, editing and deletion of individual memories are not documented in the accessible vendor source.
Access boundariesNot publicly established
Agent and channel boundaries
Personal devices are the stated deployment area. Memory isolation between users, projects and devices remains publicly unresolved.
RetrievalNot publicly established
Retrieval
A search or retrieval mechanism for saved memories is not described in the accessible vendor source.
New conversationsNot publicly established
Session reset and compaction
The accessible sources do not establish memory retention across session changes or context compaction.
