To reckon is both to predict and to settle accounts against reality — for decision-making instead of bookkeeping.
You make the decisions. Reckoner keeps them honest.
Loading your ledger…
Three questions, then the seal.
Low capital isn't a reason to wait. It's the reason to test small and let reality answer fast.
Real people or a real system. Not "the internet." Not "my future audience." If no one can say no, the test doesn't exist yet.
Watch for the escape hatches: "it's too early to tell," "I just need consistency," "this will pay off later." Your rulebook calls those untested claims.
Claims want to become beliefs. Make them earn it.
Verified claims earn their way in. Everything else gets parked — and parked claims don't get to drive your decisions.
What you let in, and what's still waiting outside.
Nothing logged yet. Next time something lands in front of you, bring it here before it moves you.
Sealed, waiting on reality.
No calls yet. Seal one you'll want to check yourself on later.
Raw notes, sealed as-is. Don't clean them up — the mess is the evidence.
Not a judgment. A mirror with a memory.
Where the record lives.
Nothing to settle yet. Go live your life; we'll remember.
One file: your record, sealed, with the rules that keep any AI honest about it. Download it, upload it to the AI you already use, and it works for you — on your facts, under your rules.
The file is a copy for the AI. Your ledger stays here, sealed. Nothing is uploaded anywhere by this app.
Point it at a folder your cloud drive syncs, and every seal lands there on its own.
Works in Chrome and Edge on a computer. Choose a folder inside OneDrive, Google Drive, or Dropbox and the file follows you everywhere — on a phone, load it with Import ledger. This app still sends nothing anywhere; the folder is yours, and so is what's in it. Step-by-step instructions.
Every sealed decision is hashed, and every hash includes the hash of the entry before it — a chain. Change one word of any entry that has entries after it, and the chain breaks visibly under "Verify the chain." Which means each new decision you seal hardens every one before it: the more honestly you use this, the more tamper-evident your history becomes. Export your ledger and the receipts travel with it.
What this does not do: stop you. The newest entry isn't hardened until the next one lands on top of it. You could delete the whole ledger and start over. Your data lives in this browser, under your control, and no one else holds the keys — so the seal is a promise you make to yourself, made awkward to quietly break, not impossible. Real cryptographic custody (where even you can't rewrite history unnoticed) is what a server-backed version would add. This version tells you the truth about itself instead of overclaiming.
Nothing you type leaves this page. There is no server, no account, no tracking.
