About Hindsight

Hindsight is a decision journal built around one moment: finding out whether you were right. Write down a decision, what you expect to happen, and how confident you are — then seal it like a letter. On the review date you chose, the letter comes back. Break the seal, compare your prediction with reality, and watch your calibration take shape. Key Features: - Seal decisions with a wax-stamp ritual — sealed letters are immutable, no quiet edits after the fact - Pick a review date, get a quiet reminder when the letter is due, and optionally add review dates to your calendar - Break the seal to face your past self: record what happened and the one lesson you'd keep - The Mirror shows your calibration — how often your 80% turned out to be a 50% - Reviews due at a glance in the menu bar and dock badge - Export any reviewed decision as a typeset PDF letter, or your whole ledger as Markdown - Local-first: no account, no cloud, no telemetry Everything lives on your Mac. The only person Hindsight reports to is the one who wrote the letter.
