Subzero is finally outtttttt!!!!!!!!!
I built SubZero - a tool that finds hidden subscriptions in your bank statements. Here's why.
A bank statement is the most honest document you own. Every charge. Every subscription you forgot about. Every "free trial" that started billing you six months ago.
Built a detection pipeline that cross-references known vendors, fuzzy matches, structural patterns, and behavioral analysis.
The result: a tool that reads any bank statement PDF and tells you exactly what subscriptions you have, what they cost, and what to do about them. The dashboard is dead simple:
→ Overall rating: B (3 subscriptions, £1,085/mo)
→ You could save £141/yr
→ Your subscriptions grouped into: Cut these / Overpriced / Review / Keepers
→ Click any one to see why it's flagged and exactly how to cancel or negotiate
No jargon. No charts you don't need. Just the answer and the next step.
Tech stack: TypeScript, Next.js, mupdf, coordinate-based PDF extraction, vendor database with 500+ known services, single-occurrence detection.
Accuracy verified against reference PDF. Output: 13/13 transactions matching, 3 subscriptions detected, 0 false positives.
Free. No AI hallucination - because your money is too important to guess.
