Every month, the bank statement sits there, a wall of entries nobody wants to touch. Debit, credit, investment. Each line needs a category: personal or official, for whom, and whether the reimbursement came back. The monthly picture stays invisible.

I recorded a voice note in August twenty twenty-six with a simple thought. What if two people at home drop their statements in, AI handles the familiar stuff, and the rest goes swipe left, swipe right. Phone-first, the way a dating app works, but for money. One shared ledger. An accountant closes the books.

I once sketched a gamified finance dashboard, called Financial Clarity. Hisab is that idea, grown up. Still just brainstorming, but the kind that feels worth finishing.

Reconciling bank statements takes longer than it should. Every transaction demands a category, personal or official, and if official, it needs a department, a person, and a note about whether the reimbursement ever came back. Reimbursements slip. The monthly picture stays invisible.

I recorded a voice note about this in August 2026. The idea that came out: two people feed their household statements into one place. AI handles the recurring items it already recognizes. The rest you swipe through, left or right, borrowing the card pattern from dating apps. Everything lands in a shared ledger, phone-first, synced. An accountant reviews the full picture and produces tax statements for both of you.

I call it Hisab. It does not exist yet. Status is brainstorming, but the problem it addresses is real enough that I felt the pull to build it.

Hisab is the utility-first successor to an older idea I called Financial Clarity, which leaned on gamification. That was a start. This is the version that is useful rather than clever.
