Notes stay home
Synthesized answers travel. Files don't.
Your team's knowledge, without your team's privacy.
Vantell lets personal second brains answer each other's questions — while every note stays on its owner's machine.
We see 0.25% of your brain.
A real vault: 187,412 notes. Shareable: 475. We see a quarter of one percent of your brain — and nothing else.
How it works — the way a healthy office already does
-
You don't read a colleague's notebook
It stays closed, under its owner's arm — where it has always been.
-
You knock and ask
The door has a handle — and it is visibly on the inside.
-
They decide what to tell you
An answer leaves in their own words. The notebook never opens.
Vantell digitizes the knock, never the notebook.
Sharing is not binary
Five disclosure levels, mirroring how people actually share. Everything above a whisper is a decision — yours.
- L0 Existence
"Someone here knows this." Anonymous, automatic.
- L1 Attribution
"Tim knows about this." Standing consent.
- L2 Abstract
A short synthesized answer — never a quote, never a file.
- L3 Depth
A detailed synthesis. Sara asks for depth. Your phone buzzes. You decide.
- L4 Raw
The page itself — only for notes you explicitly marked raw-shareable.
Three principles, built in — not promised
Can't, not won't
The software that could read your private notes has no network. The software with network can't read them.
You see everything
Every question ever asked of your brain, in your audit log, forever.
Knock first.
We're opening Vantell to a small group of pilot teams. Leave your address and we'll knock back.
Honest small print: the waitlist backend isn't built yet — this opens your email app instead. The first knock is on you.
