What Lightsplit does in ChatGPT
The Lightsplit plugin is a shared money ledger for groups, run through conversation. You create a group for a trip, a household or a team and log expenses, income and settlements in the chat. Other people can join the group through the web, LINE or Telegram.
Costs can be split equally, by weight or with custom amounts, and different currencies can be mixed in one group. You can attach receipts to entries. When it is time to settle, Lightsplit works out who should pay whom with the fewest transfers, so nobody has to send money back and forth.
There is more than splitting. Groups can keep a shared to-do list, set budgets, and see spending broken down by category. That makes it useful for a holiday house or a flat share where the same people spend together over weeks, not just for a single dinner bill.
