Money ruins friendships because of ambiguity. We realized that the anxiety at the end of a group dinner isn't about paying the bill—it's about the friction of figuring out who owes what.
Dumb calculators split everything evenly. They punish the person who ordered a salad by making them subsidize the person who ordered steak and cocktails. That isn't fair. And when things aren't fair, relationships suffer silently.
DemiTab was built as a deterministic engine. We scale third-party discounts proportionally. We distribute taxes based on actual consumption. We auto-waive zero-rupee shares.
We designed DemiTab to be invisible. You snap a receipt, the AI processes it in milliseconds, and the math is handled. No arguments, no spreadsheets, no group chat drama.
Because your time is better spent enjoying the dinner, not auditing the receipt.
