Prompt Optimizer — Free, No Signup

Analyzes your prompt across 12 dimensions — clarity, specificity, structure, tone — then rewrites it with smarter wording, explicit constraints and step-by-step framing. No signup required.

How it works

1. Paste your prompt: Any prompt you’re currently using with ChatGPT, Claude, or another AI tool.
2. Get a 12-dimension analysis: Clarity, specificity, structure, tone and more are scored, with the specific weak spots flagged.
3. Use the rewritten version: A sharper prompt with explicit constraints and step-by-step framing, ready to copy back into any AI tool.

Frequently asked questions

Which AI models does the optimized prompt work with?
The rewritten prompt is model-agnostic — it’s meant to be pasted into ChatGPT, Claude, Gemini or any other chat-based AI, not tied to one provider.

Is my prompt uploaded anywhere?
No — the analysis and rewrite run entirely in your browser.

What are the 12 dimensions it checks?
They cover clarity, specificity, structure, tone, context, constraints and similar prompt-engineering fundamentals — each scored individually so you can see exactly what to fix rather than one opaque overall score.
