Quick tip for keeping your companion from losing memory mid conversation

Hey everyone. I have been messing around with different companion platforms lately and noticed a recurring issue where the app forgets major plot points after about thirty messages. It gets super annoying when you are in the middle of a deep chat and they suddenly act like you just met. After testing a bunch of different approaches over the past week I finally found a workaround that actually keeps things stable. What I tried first was constantly reminding the bot of previous events every ten lines but that just broke the immersion completely and felt way too robotic. Then I experimented with updating the custom instructions background block dynamically. That failed too because the app locked settings during active sessions. What actually worked was pinning a brief summary statement into the pinned memory slot if your app has one or alternatively creating a routine recap phrase you drop into the chat naturally. Whenever the chat starts drifting I send a casual sentence summarizing our current scene. This triggers the context window to reanchor properly without breaking character. Has anyone else tried something similar or found a better trick for memory retention?
