Who it is for
Travellers spending heavily on a trip in a season where rain would undo it.
WeatherPromise
Rain cover that refunds a trip's cost
Overview
What WeatherPromise does
WeatherPromise sells a weather guarantee for a holiday. Destination, dates, and the amount spent on the trip produce a quote specific to that trip, and buying it puts the cover in place.
After purchase, a personal dashboard tracks conditions during the trip. Rainfall is measured against independent official sources, with NASA and NOAA named in the record, rather than by the traveller reporting what happened.
If rainfall passes the agreed threshold, WeatherPromise sends an email. Confirming the details releases the payment, and no evidence of the ruined days is required. The refund is the full trip cost as declared at the time of purchase.
What stands out
Payouts are triggered by measured rainfall against a stated threshold, so no claim has to be argued after the fact.

Where WeatherPromise is listed
WeatherPromise is listed in the ChatGPT apps directory only. WeatherPromise, Inc. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
