Hi Product Hunt! 👋 I'm Anthony. If you are building an AI wrapper, a RAG application, or integrating LLMs into your backend, you already know the pain of predicting costs. Staring at OpenAI, Anthropic, or Gemini pricing pages trying to manually calculate a mix of input tokens, output tokens, and vector database storage is a nightmare. I built TokenMath.io to solve this. It is a suite of 11 fast, transparent calculators designed to help you plan your full AI stack costs before you ship. What's inside: LLM Token Estimators: Compare projections across top frontier models. Infrastructure Planners: Estimate Vector Database storage and Embedding generation costs. Media Calculators: Project costs for Image Generation and Audio Transcription. The Engineering Focus: I built this with a strict focus on speed, privacy, and a zero-latency UI. Every calculator provides transparent math (showing you the exact formulas behind the estimates) and versioned pricing so you always know exactly when the API pricing was last verified. I would love to hear what models or specific infrastructure calculators you want to see added next. I'll be hanging out in the comments all day to answer questions!
