Perseuss
Side-by-side shipping rate estimates from three carriers
Overview
What Perseuss does
Perseuss LLC built a rate comparison tool covering USPS, UPS, and FedEx. Given an origin, a destination, and a package weight, it returns estimated prices and delivery windows for each carrier next to one another.
The listing is explicit about the boundary. Rates are informational estimates drawn from EasyPost, and the app neither books shipments nor processes payment. Completing a shipment means continuing to the chosen carrier directly.
Suggested situations are price comparison across carriers, transit time estimates, and cost planning before a shipping decision. The single example prompt asks the cost of sending a twelve pound parcel from New York to Detroit.
What stands out
It states plainly that it stops at estimates, leaving booking and payment to the carrier.

Where Perseuss is listed
Perseuss is listed in the ChatGPT apps directory only. Perseuss LLC 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.
