This card was only tested on the new version of SillyTavern staging. If you have trouble tracking how long you've been away, go to advanced definitions, find character's note, and change {{idleDuration}} to {{idle_duration}}.

So, for the card to work properly, you need to go to the extensions settings and find Quick Reply. Then, when you have the card chat open, import Lilith.json into Character Quick Reply Sets and check the "Buttons" box. This way, a SAVE button appears; when you finish the chat, you can press it. The short chat summary will be saved as a lorebook entry. Unfortunately, I couldn't find a way to immediately add it to persistent memory, so I need to change the strategy to persistent (blue circle).
