AICostNest's answer:
AICostNest was created to solve a common problem in AI product development: teams often understand model pricing, but still struggle to estimate what their real monthly usage might cost.
A single request can look inexpensive, but production usage changes the picture quickly when you add users, repeated conversations, long context, RAG retrieval, reasoning models, tool calls, and caching assumptions.
AICostNest was built as a practical planning tool to help developers and product teams estimate these costs earlier, compare scenarios, and avoid surprises after launch.
AICostNest's answer:
AICostNest is built as a modern static web application.
