- Find a year of forgotten FSA-eligible purchases across three retailers and file 15 claims with an AI agent in CursorRecreated promptEvidence: Described by poster
Ramesh Raman dislikes filing reimbursements, so they pulled 12 months of receipts from three retailer accounts and had an LLM classify every item as FSA-eligible or not. They checked the ones it got wrong themselves until every eligible item had a PDF receipt, then pointed Cursor at their reimbursement portal to file the claims. From 600 transactions it submitted 15 claims worth $242.87, pausing for approval before every upload; they reviewed everything at the end. The first upload took about 2 minutes and the last under 30 seconds. It took about an hour, for a chore they'd put off for months, and mostly recovered small forgotten buys like Tylenol.
