CheyX
Check AI model costs before you run a prompt
Paste any prompt, pick an expected output size, and CheyX estimates what it'll cost across 22 models — Claude, GPT, Gemini, Mistral, DeepSeek, Grok, Perplexity and Groq — sorted cheapest to most expensive. Includes a model recommendation engine that detects what your prompt is trying to do (coding, research, reasoning, chat) and picks the best fit. Plus batch/cache pricing mode, context window warnings, shareable links, and cost history. No login. No server. Runs entirely in your browser.
Hey PH! Built this after getting surprised by API bills one too many times. Would love feedback — especially on whether the model recommendations feel accurate for your use case. Happy to answer any questions!
