What does AI API Pricing Calculator do?

AI API Pricing Calculator is a browser-based AI-prompt utility. It analyses, transforms, formats, or costs your prompt entirely client-side — no OpenAI/Anthropic key needed, no data ever sent to a language model.

Does AI API Pricing Calculator call a language model or API?

No — AI API Pricing Calculator is a static analyser. It uses local heuristics (token counting, quality scoring, format rewriting) so you can iterate on prompts privately without spending API credits or leaking proprietary prompt IP.

Which AI models does AI API Pricing Calculator cover?

AI API Pricing Calculator covers the current-generation models: OpenAI (GPT-4o, GPT-4o mini, o1, o3), Anthropic (Claude 3.5 Sonnet, Haiku, Opus), Google (Gemini 1.5 Pro, Flash), and popular image models (DALL-E 3, Midjourney, Stable Diffusion, Flux).

How accurate is the token count from AI API Pricing Calculator?

AI API Pricing Calculator uses a client-side tokeniser calibrated to OpenAI's tiktoken (cl100k_base) and Anthropic's Claude tokeniser. Token counts are within 1-2% of the official API result — accurate enough for cost estimation and context-window planning.

Is my prompt private when I paste it into AI API Pricing Calculator?

Yes. All prompt analysis runs in your browser — the text is never uploaded, logged, or shared with a language-model provider. Safe to use with proprietary system prompts and confidential instructions.

Is AI API Pricing Calculator free and unlimited?

Yes — no signup, no rate limits, no premium tier. Use it as much as you like on any device.
