I was comparing API costs between GPT-4o, o3, and o4-mini for a project and couldn't find a simple way to check costs with my actual prompts. Every calculator I found used generic examples, not my real text. So I built this — paste your prompt, get exact token counts (via tiktoken for OpenAI models), and see pricing across 10 models side by side. Everything runs client-side, no API keys needed. Would love feedback on what models or features to add next!
