Show HN: BudgetFast – Upload a bank statement screenshot, AI does the rest

I was tired of manually updating my budget. Most budgeting apps require bank integrations or CSV exports — mine just needs a screenshot. Upload it, and AI extracts every transaction. You set rules once ("NETFLIX = Entertainment"), and it categorizes itself automatically from there. Built with Next.js, MongoDB, and Claude API. Happy to answer questions. budgetfast.co — early access open.
