What a Wrapper Is

A "wrapper" is a product or service built primarily by calling another company's AI API, with minimal proprietary technology added. The core value proposition (the intelligence) is entirely rented from the underlying model provider.

Wrappers are extremely common because building on top of GPT-4 or Claude is fast and cheap. But they're strategically fragile: the model provider could ship the same feature natively, undercutting the product. They're also hard to differentiate, if your entire product is "GPT-4 with a nice UI," a competitor can replicate it in a weekend.

Successful AI products built on top of model APIs add genuine proprietary value: unique data flywheels, deep domain expertise, integrations into existing workflows, or specialized fine-tuning that creates a real moat.
