Tool 03 · Pillar 1
Leak-Detection Engine
Run it on the last Sunday of every month. It compares this statement against your own baseline and tells you only what changed: new subscriptions, quiet price rises, double charges and category drift.
Runs entirely in your browser. Your file is never uploaded — not to us, not to anyone.
Drop this month's statement here
The same CSV export you used for the expense sorter — one month is enough once you have a baseline.
Your first run sets the baseline
Load three months the first time. The tool learns what your normal looks like, then every month after that it only has to tell you what changed — which is the only part worth your attention.
