Lums AI: The Accounting Engine
Your budget, mathematically guaranteed to be correct.
Ever had a transfer between accounts count as "spending" twice? Most apps fail there, losing history after 90 days and leaving you with budget estimates that don't add up. Lums changes that. We’ve added a real Accounting Engine that automatically ensures transfers are verified, your complete history is stored forever, and our AI answers your questions using 100% verified facts instead of messy guesses.
Hi Product Hunt community! 👋
I’m Marion, CMO at Lums. Since our first launch 2 months ago, we’ve been listening closely to your feedback and ideas to help Lums evolve alongside you!
A great budget needs total confidence in your numbers. We’ve all felt that spark of motivation fade when:
❌ A simple transfer counts as a "double expense".
❌ Your history expires just when you need to compare trends.
To fix this, we’ve built a professional Accounting Engine into Lums. It’s the smart "brain" ensuring every dollar is mathematically accounted for.
✅ What’s new:
⚖️ Seamless Accuracy: Internal transfers are verified automatically—no more double-counting or manual fixes.
📜 Permanent History: Access your complete financial journey anytime; your data is stored in an immutable ledger that never expires.
🎯 AI You Can Trust: Our assistant now gives you answers based on 100% verified data, ensuring total financial clarity.
We would love to get your feedback on this! Is this something you’ve already faced while using a budgeting app? Let's chat below! 👇
I’m the CPO at Lums, and I’m excited to share what we’ve been building: The Accounting Engine for personal finance.
Most budgeting apps are built around tracking and categorization. Useful, but often brittle. We wanted to go deeper and build personal finance on top of real accounting principles, specifically double-entry bookkeeping, so your money system stays consistent, auditable, and always adds up.
With Lums, you can chat with your finances, create a budget in minutes, auto-categorize transactions, manage multi-currency accounts, and understand where your money is going without wrestling with spreadsheets.
Our goal is simple: bring the rigor of accounting to everyday personal finance, without making it feel like accounting software.
I’d love your feedback, especially from anyone who has struggled with budgeting tools, spreadsheets, or keeping their financial picture organized across accounts and currencies.
Happy to answer questions throughout the day!
Hello PH!
Building this was one of the most important decisions we made as a team.
The double-counting problem isn't cosmetic. It corrupts every number downstream, including what our AI tells you. We could have patched it. Instead we built a real double-entry accounting engine from the ground up.
Same standard banks use.
If you're going to trust an app with your finances, the math has to be airtight.
That's what this is. Congrats to the whole team on shipping it. 🚀
