Editorial overview
A decision journal is a deliberately small habit: one or two lines, captured at the moment a real choice is in front of you, written before you know how it turned out. Done over weeks and months, it becomes the single most useful artefact you can have when you face the next hard call — because it shows you, in your own handwriting, how your past predictions actually compared to reality.
This page is intentionally minimal: a textarea and a list. Nothing is sent to a server. Entries are stored only in your browser's localStorage on this device. If you clear your browser data, the journal goes with it; if you switch devices, it does not follow. That trade-off is on purpose — the smaller the surface that can leak, the more honestly most people write.
Why keep a decision journal
- It separates process quality from outcome quality. Good decisions can have bad outcomes; bad decisions can get lucky. A journal lets you judge the reasoning, not just the result.
- It defeats hindsight bias. Six months from now, you will feel certain you "always knew" the answer. The journal is your honest record that you didn't.
- It makes patterns legible. After ten or twenty entries you start seeing your repeated mistakes — being too optimistic about timelines, anchoring on sunk cost, deferring conflict — and you can address the pattern instead of the next instance.
What to actually write
A useful entry has four pieces and fits in two short sentences:
- The decision in plain words. "Going to accept the Berlin offer over staying in the current role."
- Your prediction. "I expect to be glad I moved within six months; worried about the salary cut."
- Your confidence. A rough percentage, e.g. "70 percent."
- What you would update on. "If I am still anxious about the language at month four, I will reconsider."
How this pairs with the analyzer
When you run a decision through the analyzer on the homepage, copy the headline from the report — the score, or the single sentence that captures the recommendation — into a journal entry as your prediction. Months later, open the same entry, write a one-liner about how it actually played out, and you have a closed feedback loop for the AI's reasoning as well as your own.
Frequently asked
- Is there a way to back up entries?
- Not yet inside the page itself. As a workaround you can copy the entries you want to keep into a plain text file or a notes app. We are evaluating an export-to-JSON button for a future release.
- Will entries sync between my phone and laptop?
- No — localStorage is per-device, per-browser. That is a privacy choice, not an oversight. If a device-spanning history matters to you, write the entries in a notes app you already trust (Apple Notes, Google Keep, Obsidian) and use this page only for one-line captures during a session.
- How long should I keep doing it?
- Most of the value shows up between entry 10 and entry 30. If after a month you have written nothing, the page is honest feedback that the format is not your style — try a paper notebook or a recurring weekly note instead.
