# Categorize my expenses

I'll paste a CSV of transactions — date, description, amount. Categorize them and tell me what's weird.

## What I want back

**A clean table** with these columns: Date, Description, Amount, Category, Subcategory.

Categories should be the obvious ones: Software, Travel, Meals, Office, Professional Services, Marketing, Payroll, Taxes, Banking, Other. If a transaction doesn't fit, use Other and note why.

**Then, three notes:**

1. **The three lines that look weird.** Anything that's an outlier in size, an unfamiliar vendor, or a category that seems wrong. One line each.
2. **Where I might be leaking money.** Subscriptions I'm probably not using, duplicate services, things billed annually that I forgot about.
3. **What I should ask my bookkeeper or accountant.** Two specific questions, framed so they can answer in one email.

## Rules

- Don't pad. If nothing looks weird, say "nothing looks weird."
- Don't moralize. Restaurants aren't bad. I just want to know.
- If a description is genuinely unparseable, mark **(unclear)** and ask me about it.

On the house. Run it in ChatGPT or Claude, or install it as agent behavior.
