Who it is for
Shoppers who compare options before buying and want to be told when a price moves.
Overview
What Penny does
Penny handles two shopping jobs in one place: finding products and watching what they cost afterward. A request can be typed as a description, or an image can be uploaded to look for similar items.
Options come back in the chat, where questions can narrow them down before settling on one. Once something is chosen, Penny can begin monitoring its price and report later changes.
Example requests run from a gift for a young cousin who likes racecars, to long distance running shoes, to a list of everything currently being tracked.
What stands out
Image search and ongoing price monitoring come from the same app rather than two separate ones.

Where Penny is listed
Penny is listed in the ChatGPT apps directory only. Channel3 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.
