Ghost Charges: a local Gemma 4 finds the subscriptions still haunting your bank statement

说明与用途

Ghost Charges 使用本地 Gemma 4 模型读取银行对账单行，随后 Python 代码对订阅费用进行分组和标记，生成简洁的摘要表格。

问题

Users cannot easily identify recurring subscription charges in their bank statements, leading to unnoticed fees.

结果

Ghost Charges identified 7 recurring charges totaling $1,510.52 per year in a synthetic statement, with detailed reasons for each flag.

工作流

• Export bank statement as CSV
• Run the Ghost Charges command on the CSV
• Gemma 4 E2B reads each unique line and outputs merchant name, quote, and kind
• Python rules validate the reading and merge similar merchant names
• Python groups charges by merchant and frequency, calculates yearly cost, and flags anomalies
• Output a table of recurring charges and audit trail

证据

Ghost Charges finds them. Export a CSV from your bank, run one command, and get a table like this:

I scored both versions against hand-made answer keys: ... Gemma + rules 8/8 exactly right.
