About

CostMyAI

Independent AI economics intelligence. Free, no-account-required tools for founders, developers, and teams who need to understand what AI actually costs before they scale.

Why CostMyAI exists

AI API costs can catch teams completely off guard. A prototype that runs for a few dollars a week in development can generate a five-figure monthly bill when it hits production scale. Provider pricing pages are scattered, inconsistent, and rarely give you the forecasting tools you need to plan a budget or understand what those costs mean for your margins.

The Analyzer is the core product. Upload your real usage export from any provider. CostMyAI groups your workloads by task type, checks every potential model switch against named public benchmarks (AA Coding Index, TAU2, GPQA, IFBench, LCR), and tells you which savings are certified and which ones we refuse to claim.

Every calculation runs entirely in your browser. No servers processing your inputs, no accounts required, and no data sold.
