Conversation history
Updated November 9, 2026
Conversation history is the stored record of past messages between you and an AI app.
Having a history isn't the same as being remembered. Snapchat's My AI shows the difference: Snap says chats are stored until you delete them, yet My AI won't remember details from prior conversations over time. The record exists, but the app doesn't draw on it that way.
When comparing companions, ask two things: does it use your history to keep up with you, and how do you delete it? With Hallie, the history is your Messages thread with her. Deleting that thread only clears the copy on your phone; to request deletion of your data, email hello@hallie.io.
