Most AI memory is a bigger context window with better marketing
Most "AI memory" demos are a bigger context window with better marketing.
What actually sticks is a tiny pipeline, not a model feature: decide what's worth keeping, park it somewhere, retrieve it later, and have a rule for when to stop keeping it. Skip that last part and you just accumulate sludge until the agent gets worse.
I tore the word "memory" into the five mechanisms people mash together (working context, episodic logs, durable facts, retrieval, and forget rules), then wrote a ~90-line version that does the job without a fancy product.
If you're building an AI cofounder that "remembers the company," the forget side is the part most demos skip. That's where the product either stays useful or turns into noise.
