Frequently asked questions
- Is Savings Calculator really free?
- Yes — fully free, no email gate, no signup, no sales call. All Prism tools live on this page and similar dedicated tool pages.
- What data does Savings Calculator use?
- The calculations use current public provider pricing (Anthropic, OpenAI, Google) and Prism's published cache-economics math from production traffic. Nothing about your usage is captured — the calculator runs entirely in your browser.
