The pain point is real: parents get cryptic charges and have no way to trace them. The solution is clever—using existing data sources without needing platform access. The hard part is classification accuracy: a single misattributed charge destroys trust. Distribution is narrow but passionate: parenting forums and gaming communities. For this to work, the merchant code decoder must be near-perfect out of the gate, or parents won't onboard.

The idea

The pain point is real: parents get cryptic charges and have no way to trace them. The solution is clever—using existing data sources without needing platform access. The hard part is classification accuracy: a single misattributed charge destroys trust. Distribution is narrow but passionate: parenting forums and gaming communities. For this to work, the merchant code decoder must be near-perfect out of the gate, or parents won't onboard.

Parents discover the problem only after a surprise charge. Merchant codes are cryptic; no existing tool decodes them for gaming. Platform-specific parental controls don't cross platforms.

Parents complain about surprise gaming charges on forums regularly. No existing tool decodes merchant codes across platforms. Email receipts are a universal data source parents already have.

Clear pain, no direct competitor. Financial surprise and loss of control.

Why now

Heuristic scoring based on model judgment, not factual measurement.

LLMs can classify merchant codes accurately. Rising concern over kids' digital spending. No cross-platform spending tracker exists.

The market timing is favorable: demand is validated by high complaint volume and regulatory attention, while LLM technology enables a novel solution. However, no direct competitor exists yet, suggesting an open window.
