Please help - I saw a reel about how to better use Anthropic models in tandem with something on your local desktop. I thought it was very motivating and exciting, but now I cant find the reel again, and I don't even know the search terms to use to search for it

Overview

I know part of it was about persistent memory, using files stored on your local machine, and part of it was about how to make your agents better and more useful by something saved on your local machine, and there were other cool sounding features, something about ways to save tokens, but I don't remember the rest. I see there is "no tool request" rule, so can someone without saying a product name, just say what the category name for this type of tool is? or what search terms to use
