Have you ever noticed how the things you’ve learned just… vanish? The clever quote, the perfect analogy, the critical framework—they’re there when you’re safe at home, but the moment you step into a meeting, or a crisis, or a real conversation—poof. Gone.
I’ve been thinking about this a lot lately. Tomorrow night marks the 10th anniversary of Get App (得到), and through these ten years we’ve helped millions of people acquire knowledge. But I keep asking: how much of that knowledge is actually being used? The saved lectures, the highlighted passages, the neatly organized notes—they sit there, waiting. And when life calls, they don’t answer.
Why? Because our tools don’t know us. They handle "information"—they store, index, search. But they don’t understand who you are. They don’t know the way your mind makes connections, the experiences you’ve had, the problems you’re facing right now. So when you need that piece of knowledge, it doesn’t come to you. It’s not that you’ve forgotten it; it’s that the tool has no idea you’re in a situation where it matters.
Think about a time you went into a job interview. You’d prepared dozens of frameworks and stories. But when the interviewer asked a specific question, your mind went blank. Later, driving home, the perfect answer came to you—effortlessly. That’s not a memory failure. It’s a context failure. The knowledge was there, but your brain didn’t trigger the right retrieval cue. A tool that knows you could have whispered: "Remember that framework from Professor X? This is exactly the moment to use it."
Cognitive science calls this "inert knowledge"—stuff you can recall in a quiz but can’t apply in real life. The only way to activate inert knowledge is to bind it to your personal experiences and problems. That’s what a truly intelligent assistant should do: learn your life, and serve you the knowledge exactly when it’s needed.
That’s what we’ve been building at Get. Tomorrow night at 7 PM, we’re going to unveil something that, I believe, will change how you think about learning. Not just another AI tool, but a system that finally understands you. It knows what you’ve learned, what you care about, and when you need a nudge. It’s the answer to that feeling of knowledge vanishing.
See you tomorrow.
