Downloaded bank statement PDF. 847 transactions. Somewhere in there: subscriptions I forgot about.
Built 6-node analyzer. Found $1,200 annually in subscriptions I didn't use. Three services I'd forgotten existed.
THE SUBSCRIPTION CREEP:
$12/month here. $29/month there. Free trial converts. Card gets charged. You forget. Annual cost adds up. Nobody tracks it.
Bank sends PDF statement. 50 pages. Who reads that?
THE DISCOVERY:
Document extraction pulls every transaction with category. Code analyzes spending patterns. Groups by category. Flags subscriptions.
Six nodes. Complete spending analysis from PDF to Slack report.
THE WORKFLOW:
Gmail trigger catches statement email → Get attachment → Document extraction pulls all transactions with amounts and categories → Code analyzes spending by category → Sheets logs monthly summary → Slack sends analysis report.
THE ANALYSIS LOGIC:
Code calculates:
- Total by category (Income, Subscriptions, Dining, Shopping, etc.)
- Savings rate percentage
- Large transactions over $500
- Monthly comparison trends
Slack report shows spending breakdown. Where money actually goes. Not where you think it goes.
THE SUBSCRIPTION DETECTION:
Recurring amounts same day each month = subscription. Code flags them. Lists them separately. You decide which ones you actually use.
Found three I forgot about: Old project management tool ($29/month), unused design software ($15/month), podcast hosting I discontinued ($19/month).
THE TRANSFORMATION:
Before: Bank statement arrives. File it. Never look at it. Surprised by balance.
After: Automatic analysis. Spending patterns visible. Subscriptions surfaced. Decisions made with data.
THE NUMBERS:
847 transactions analyzed
12 categories tracked
$1,200 annual subscriptions found
3 forgotten services cancelled
Savings rate calculated automatically
What spending patterns would surprise you if you actually looked?
