Log the situation
Describe what happened and the mistake you made.
How it works
Save, compare, repeat.
Four steps from a fresh moment to a reusable record. No setup, no account.
Identify the trigger
Note what led to the error and any signals you missed.
Extract the lesson
Write the concrete lesson in one sentence.
Define next action
Save what you will do differently when the situation repeats.
What you can save
Lessons feel obvious right after a mistake and fade before the next similar moment.
The app is short on purpose. The notes field is free text so the record can hold anything that does not fit a label.

Comparison
Why not just use a notes app or a spreadsheet?
You can. LessonSaver is for when a free-form note is not enough and a full database is too much.
vs. A notes app
Lessons get buried. LessonSaver keeps them as a searchable playbook.
vs. A journal
Journals are open-ended. LessonSaver uses the same capture structure every time.
vs. Memory
The lesson feels permanent right after the mistake. It is not.
