Not another notes app — a living second brain
Your second brain.
It remembers what you forgot.
Memento is your Second Brain: it connects ideas across months, surfaces hidden links, and turns notebooks into a system you can search, brief, and act on every morning.

"Linked to your March design brief — same constraint, new angle."
The real problem
You don't need more notes. You need a second brain.
Folders fill up. Search fails. Ideas die in silence. A Second Brain finds the threads between what you capture — so yesterday's thinking powers tomorrow's decisions.
That's Memento: a Second Brain that connects itself while you write.
Memory Echo
The moment your Second Brain talks back.
While you write, Memento finds links across your notebooks — not just matching words, real connections. You can open both notes side by side.
