Why I built this
I'm a finance guy. Numbers are, quite literally, my job — budgets, forecasts, reconciliations, all day. And yet every single month, cash would leave my wallet and just... disappear. Not stolen. Not lost. Just untracked.
Card payments were easy — the bank remembers for me. But the moment I withdrew cash, the money left the record entirely. A thousand rupees for lunch here, five hundred for a tuk-tuk there. By the end of the month I'd have no real idea where a huge chunk of it had gone.
So I built myself a hack. Every time I paid for something in cash, I'd open WhatsApp and send myself a message.
The habit that started it all — now built right in.
It wasn't elegant. It was just a diary, one text at a time, sent to an audience of one. Then, at the end of every month, the real work started. I'd scroll back through weeks of these messages, open Excel, and type every single one in by hand — trying to piece together where my money had actually gone. It worked. It also took hours I didn't have.
Around the same time, I'd started experimenting with AI — not just asking it questions, but actually building things with it. And somewhere in there it clicked: the thing I wanted already existed, half-formed, inside my own WhatsApp habit. It just needed to become a real app — something as fast as texting myself, but that did the remembering for me.
That's Salli. Same instinct as those messages — log it the second it happens — minus the month-end Excel ritual. Built in Sinhala and English, for the way money actually moves in Sri Lanka: Keells and Cargills, PickMe and LECO, cash and card.
