A cryptic charge on your statement and no idea what it is
“There's a charge labeled 'SP* HLDNGS 8009...' on my card. Is it fraud or something I forgot I signed up for? Googling these descriptors is a nightmare.”— r/personalfinance ↗
Cryptic merchant descriptors are a universal pain and the existing 'what's this charge' sites are ad-farms with stale, unreliable data. A clean, crowd-corrected descriptor lookup (like the 'is it open?' idea, for charges) is a trustworthy niche.
Anyone reviewing card/bank statements
Build a crowdsourced 'what's this charge?' lookup in Next.js. User searches a statement descriptor; show known matches (real merchant name, what it usually is) plus community notes, and let anyone add/correct an entry. Seed with a starter dataset. First 3 steps: (1) searchable descriptor list + detail page, (2) a community 'this is actually ___' submission, (3) a confidence/freshness signal from corroborating reports. Mirrors the 'is it open?' crowdsourced pattern.
