Connect it and ask in plain words:\n- \"Dinner \u20ac60 for the Lisbon trip, split equally\"\n- \"Who owes me?\"\n- \"What did I spend on food in September?\"\n\nChatGPT adds personal and group expenses, splits them equally or by shares, amounts or percent, records settle-ups you paid outside Monesto, and creates groups with your Monesto friends. It also reads your balances and summarizes spending by category, month, group or member. Everything lands in your Monesto ledger, where your group sees it too, marked \"via ChatGPT\".\n\nMonesto never moves money. It records and reads; payments and transfers are out of scope. Each connection reaches only the account that approved it. Entries it added can be undone for 24 hours, and you can disconnect any time from ChatGPT, from /apps in @monesto_bot, or from the link in the \"connected\" email.\n\nSign in with Telegram, email, Apple or Google. New users get an account on first connect.",
