Most budgeting apps require you to link your bank or spend hours on manual setup. Fin (USEFINAPP) works differently. Upload your bank's CSV and AI can categorize everything instantly for you. Then ask the assistant real questions about your spending and actually get answers. No methodology to learn, no bank credentials to hand over, no complexity to fight through. Just instant clarity on where your money is going. Built by an indie dev who genuinely loves feedback. $5.50/month.

Fine-tune any LLM in minutes, with one prompt

I moved to Toronto to start a new chapter of my life and career. Moving here cost an arm and a leg. When I finally settled in, I looked back at the past year and expected to see solid savings. I had a $100k salary with maybe $40k in expenses. The money should have been there. It wasn't.

That realization pushed me to actually dig in. My transactions were spread across multiple banks and cards, and piecing it together manually felt impossible. Every tool I tried either wanted me to link my bank accounts or required so much setup that I gave up before I got any answers. I just wanted to understand my money, not manage a system.

So I built fin. You upload your CSV exports, the AI categorizes everything, and within minutes you actually understand where your money went. No bank connections, no weeks of setup, no giving your credentials to anyone. Your data stays yours and the answers are immediate. That's the whole point.
