everything it logged, one link away - live, no login. open the live example →
how it works
- say hi. tap the button above, or add it to a group. it introduces itself on the first message.
- text what you spent. "spent 300 on groceries" · "uber 89" · "cine 180 ayer". it reacts 💸 when logged. any language, no commands, no forms.
- fix mistakes in words. "that was 350" · "delete the tacos" · "the uber was yesterday".
- ask whenever. "summary" · "how much on food this month?" · "send me the xlsx for july".
in a group
- it reads quietly, logs any expense someone mentions and remembers who paid.
- "paid for dinner, just milo and me" - splits only among the people you name.
- "@teresa new tab Trip" opens a tab; "@teresa close the tab" freezes it and posts who pays who.
- @mention it for the rest: "who owes what", "settle up", "milo paid me 200".
the link
- every chat gets one page: live list, totals, balances, csv/xlsx/pdf. no login.
- ask "send me the link" anytime.
- anyone holding the link can open it - say "new link" and the old one stops working.
- prefs live in chat too: "use USD", "timezone mexico city", "rename this to house".
