Route Your Wrong Answers Into the Fix That Matches Them — Free
List each wrong answer and why; the log sorts them into error lanes with counts, so the fix matches the cause instead of being the same drill for every mistake.
What this replaces
Redoing questions treats a conceptual gap and a copied digit as the same problem. This sorts them into lanes and ranks the lanes by cost, so the study time goes to the error that actually loses marks.
Tool note. This runs entirely in your browser — no account, no upload, no paid API key. Google NotebookLM is named as the free source-grounded reading path for the material you paste; its published free-tier terms were checked on 2026-09-13 and can change.
The four passes
Collect the smallest useful input
One wrong answer per line, with the reason it was wrong.
Let the log sort them
Each line is matched to an error lane and counted.
Fix the top lane first
A concept error costs more per question than a slip.
Rerun after the next set
A lane that does not shrink means the drill is wrong.

Everything you paste stays in this browser tab. Nothing is uploaded, there is no account, and no request leaves the page to generate the result; clearing site data removes anything saved locally.
What breaks, and what to do
Reason not stated
The line lands in the last lane; write why it was wrong.
Two causes on one answer
The first match wins; split them if both matter.
Lanes that do not match your subject
Rename them in a copy to match how you actually fail.
