A note becomes useful
when it can return in a different inquiry than the one that produced it.
Most notes apps let you save everything. settl asks a better question: does this thought actually hold up? Capture freely — but only ideas that pass the gate become part of your permanent archive.
FREE ON IPHONE, FOREVER · NO PAYMENT TODAY · TRIAL STARTS WHEN YOUR VAULT IS READY
Every thinking tool promises to organize your notes. settl is built around a stricter claim: most captured thoughts shouldn't become permanent — and the ones that do deserve an address, not a folder.
Nothing here is precious yet. A capture is just a thought caught before it's gone — text, voice, or pulled from something you're reading.
Fleeting thoughts stay in the open, developing, until you're ready to ask whether this one is actually worth keeping.
The Gate is a real check, not a formality — a thought has to hold up before it's admitted and numbered.
Admitted notes take their place on a wheel of numbered positions, each one sitting next to whatever thought came before it.
“A note doesn't have a subject. It has a position — next to whatever raised the same question.”THE PRINCIPLE BEHIND EVERY ADDRESS IN THE SLIPBOX
An address records where a thought was placed. Gate evidence records how it was checked. That checking comes with the Companion: one payment, no subscription. A real address is never a paid privilege.
The complete manual Zettelkasten, in your pocket.
$59.99 once. Two years of updates included. Keep using your last included version. No payment today: the trial starts once your vault is ready.
