GPTree saves memories on its own, but it does not always pick the thing you care about. Pinning makes sure it does. The scope starts at the current conversation; widen it to the project or your whole account when the fact should travel further.

Highlight text in a reply and choose Pin to Memory to save it on purpose, edited the way you want, for one chat, a project or everything.
