That’s when it hit me: we don’t have an information problem anymore. We have a retention problem. We save everything. Articles. PDFs. Tweets. Meeting notes. Video insights. Random ideas. But two weeks later, most of it is gone from our head. The insight decays. The context disappears. The connection between ideas fades. Our notes slowly turn into an archive instead of an asset. What frustrated me most was realizing I kept relearning the same things. I’d read about mental models, startup distribution, learning science, systems thinking — and every time it felt new. But it wasn’t new. I’d seen it before. I just didn’t retain it. That’s when I had an uncomfortable realization: my “second brain” wasn’t a brain at all. It was a storage locker. It stored information, but it didn’t help me remember or use it.
Most tools are optimized for storing, organizing, tagging, formatting, linking. They assume you’ll come back and reread your notes. But you usually don’t. And even if you do, rereading isn’t the same as remembering. Real retention requires re-exposure, active recall, and spaced repetition — the same principles behind learning science — but applied to everyday thinking and work, not flashcards and exam prep.
So I started asking a different question. Instead of “How do I organize my notes better?” I asked, “How do I make sure I actually remember what I capture?” That shift changed everything. What if your notes didn’t just sit there? What if they occasionally asked you to explain an idea in your own words? What if they reminded you of a concept right before you forgot it? What if they connected new thoughts to old ones automatically and resurfaced insights you saw months ago when they became relevant again? That’s the idea I started building around. I’m working on something called Neuron. The core loop is simple: Capture → Understand → Remember → Retrieve → Reuse. You throw everything in — notes, links, PDFs, highlights, voice ideas — and the system handles structure automatically. Behind the scenes it extracts key ideas, builds a living knowledge graph, generates contextual recall prompts, and schedules spaced repetition quietly in the background. You don’t “study.” You just spend a few minutes a day reinforcing what actually matters.
The goal isn’t to build another note-taking app. It’s to build something memory-first. Something that turns knowledge into something that compounds instead of decays. If this resonates - especially if you feel like you consume way more than you retain — I’d genuinely love your thoughts and criticism.
