What does AI Prompt Formatter Online do?

AI Prompt Formatter Online 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 Prompt Formatter Online call a language model or API?

No — AI Prompt Formatter Online 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 Prompt Formatter Online cover?

AI Prompt Formatter Online 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 Prompt Formatter Online?

AI Prompt Formatter Online 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 Prompt Formatter Online?

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 Prompt Formatter Online free and unlimited?

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