Free AI cost calculator. Paste your prompt to compare API pricing across GPT-4o, Claude Sonnet 4, Gemini 2.5, Llama 4, and DeepSeek R1. See token counts and monthly costs instantly.
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!
