Poplin
Estimate fees, exchange rates and arrival times for sending or receiving money across borders.
Connects to Poplin's public pricing data for international payments. Muse can estimate what a transfer to a bank abroad costs, how much the recipient gets, and how fast it arrives. It can also check receiving accounts, payout options, supported countries and recent exchange rate moves. Quotes are estimates; final terms are confirmed in the Poplin app.
Try asking Muse: "How much would it cost to send 1,000 US dollars to a bank account in Mexico, and how fast would it arrive?"

Open ChatGPT settings
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
- 2
Turn on developer mode
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
