AiCostNest - Estimate LLM API costs before launching AI features

Hi Product Hunt, I built AICostNest to make AI API cost planning easier before launch. A single LLM request may look cheap, but production usage quickly becomes harder to estimate when you add users, repeated conversations, RAG context, reasoning models, agent tool calls, and caching assumptions. AICostNest helps developers and product teams estimate text, reasoning, RAG, agent, and monthly AI API costs before shipping AI-powered features. I would love feedback on which cost scenarios or calculators would be most useful to add next.
