No. 00 About

We watched our own second brains rot, too.

KNOWNEST
A WORKING NOTE
ON WHY WE EXIST

No. 01 — The belief

We built second brains. Then we abandoned them — every time. Not because we stopped saving things. Because saving was never the hard part. The pile grew, and the pile rotted, and eventually we stopped trusting it enough to open it.

A decade of tools sold us faster capture. The newest ones sell better search. Both quietly assume a person will do the connecting, the reconciling, the pruning — the upkeep. Nobody does. That's not a discipline problem. It's the wrong job for a human.

It's exactly the right job for a librarian. So we're building one: an agent whose whole purpose is maintenance — to file each new source where it belongs, link it to what you already know, and tell you when your understanding has gone stale or started to contradict itself.

The output isn't an answer that vanishes. It's a structure that stays alive. What you learn, finally, adds up.

No. 02 The name
Knownest
knownWhat you've already learned — the things worth keeping, and keeping trustworthy.
nestA kept, living place. Tended, not stored. Something that stays warm because something maintains it.
-estThe most known you've ever been on your own subjects — because nothing you learned slipped away.
No. 03 Principles

Four commitments we won't trade away.

These aren't features. They're the reasons it's safe to let an agent touch knowledge you built by hand.

01

Maintenance is the product

Not capture, not chat. The thing we maintain and hand back is a living structure. Everything else serves that.

02

Autonomy, but never a one-way door

The agent runs on its own — and every single thing it does is diffed, attributed, and undoable. We earn the right to be unsupervised by being completely transparent.

03

Your base is yours

Full-fidelity export, always. Nothing trains on your knowledge. The lock-in we want is that it's too good to leave — never that you can't.

04

Structure over answers

An answer you can't find again is a search result. We optimize for the page you return to and rely on — the thing that compounds.

No. 04 From the team

“We're a small team building the tool we kept wishing existed every time our own notes let us down. We'd rather get a hundred people relying on a maintained base than a million saving into one that rots.”
