Fix your AI bill.
One problem at a time.

Engineering teams shipping AI features typically hit one of three infrastructure problems as their usage grows. The first is cost, paying flagship model prices for requests that simpler models handle just as well. The second is visibility, knowing the total monthly spend but not which feature, task type, or team is responsible for the majority of it. The third is routing complexity, wanting to reduce costs but not wanting to build and maintain the routing logic yourself.

PromptUnit addresses all three through one integration. One personal PromptUnit address, pasted where your app's AI address is set, connects your application to the routing and observability layer. Your own AI key stays in your app. The solutions below describe each capability in detail, and most teams start with cost reduction and add observability as their usage grows.
