What if your brain had friends?

We’ve all got notes scattered across Notion, Google Docs, and random voice memos on our phones. Ideas come to us in the shower, from podcasts, late-night convos, and then disappear into the void.

What if they didn’t?

BrainBank is the app we wish existed. A living, social knowledge graph where your thoughts get mapped, connected, and occasionally bumped into someone else’s. You drop a podcast insight - someone across the world adds a related idea, suddenly, you’re chatting. It's like notion meets Tinder for thinkers. Swipe to “bump minds,” spark collabs, or just make sense of your own chaos.

Or share it with someone who should ;)

We're making these free forever. If even one idea sparks something for you, that's a win.
