Hey ProductHunt! I'm Joseph, the builder behind Cinderfi. I started this project because I was frustrated using separate tools for budgeting and retirement planning. YNAB tells me I overspent on dining but so what? Boldin tells me I can retire at 62 but disconnected from my actual spending. Neither tool answers the question I actually care about: how does my spending today affect when I can stop working? Cinderfi is aiming to be the your one end to end financial platform by combining spending, retirement, tax optimization, and investment tracking A few things I'm proud of - Retirement cost per transaction: that $6 latte isn't just $6, it's 2 days of retirement when you compound it over 20 years - Works for both Canada and the US — real provincial/state tax brackets, not flat estimates - Privacy-first: runs offline with IndexedDB, Supabase sync is optional, no ads - MCP server: ask Claude about your retirement plan in natural language - Free tier is genuinely useful... no 14-day trial bait I'd love to hear what features you'd want to see next. I'm building in public and shipping fast I went from v0 to v1.3 in three weeks.
