\n My grandmother has trouble remembering what she ate for breakfast. But she remembers my birthday. She remembers every grandchild’s name. She remembers stories from forty years ago like they happened yesterday.<\/p>\n
Her brain figured out what matters.<\/p>\n
I used to think AI memory should be a perfect recording. Every conversation saved. Every detail searchable. Total recall.<\/p>\n
I was building it wrong.<\/p>\n
I’ve been working on Lorekeeper \u2014 an open-source memory system for AI agents. It started as a storage problem. How do I keep everything?<\/p>\n
But storage isn’t the hard part. The hard part is knowing what to keep.<\/p>\n
Think about your own brain. You don’t remember everything. You remember the important stuff. The conversations that mattered. The mistakes you learned from. The names of people you care about.<\/p>\n
Everything else fades. That’s not a flaw. That’s the design.<\/p>\n
I built a feedback loop into Lorekeeper. Every time an agent uses a memory, it can say “this was useful.” The stuff that gets used stays. The stuff that doesn’t fades.<\/p>\n
I set it up, walked away, and forgot about it.<\/p>\n
Two weeks later I asked my agent about a debugging session we’d had. A random import issue from weeks ago. I had completely forgotten about it.<\/p>\n
My agent remembered. Not because I had saved it perfectly. Because over two weeks, across multiple sessions, that specific memory kept being useful. The system promoted it naturally.<\/p>\n
It felt like running into an old friend who remembers something about you that you’d forgotten. That surprise of being known.<\/p>\n
That’s the thing nobody tells you about building AI tools.<\/p>\n
The goal isn’t perfect memory. The goal is to know what matters.<\/p>\n
A system that remembers everything is like a closet so full you can’t find anything. A system that forgets the right things is like a well-worn bookshelf \u2014 the books you actually reach for are right at eye level.<\/p>\n
I spent months optimizing how much my agents could store. The real breakthrough was teaching them what to let go.<\/p>\n
Lorekeeper is open source (Apache 2.0). pip install lorekeeper-mcp if you want to try it.<\/p>\n
Star the repo if this resonates. Helps me know I’m not the only one thinking about this. It means a lot to me, thank you!<\/p>\n
