# Prompt Optimizer Rewrite a raw prompt into a more structured version, score clarity and ambiguity, and show prompt improvement hints > Canonical page: https://elysiatools.com/en/tools/prompt-optimizer - **Category:** AI Tools - **Keywords:** prompt, optimizer, prompt engineering, llm, deepseek ## Overview Scores the original prompt on clarity, completeness, and ambiguity, rewrites it into Role, Task, Constraints, and Few-shot sections, and can optionally call DeepSeek v4 for a stronger AI-assisted rewrite. ## Inputs - **Prompt** (textarea): Paste your raw prompt here - **Use AI Rewrite** (checkbox) - **Output Language** (select) ## When to use - When your LLM outputs are inconsistent, off-topic, or fail to follow specific formatting constraints. - When you want to evaluate the quality of your prompt using objective scores for clarity, completeness, and ambiguity. - When you need to quickly convert a simple, one-sentence idea into a professional, structured prompt template. ## How it works - Paste your raw prompt into the input text area. - Choose whether to enable the AI Rewrite option and select your preferred output language. - Click generate to analyze the prompt and receive clarity, completeness, and ambiguity scores. - Copy the structured output, which is organized into Role, Task, Constraints, and Few-shot sections. ## Use cases - Refining vague marketing copy prompts to get precise tone and length variations from ChatGPT. - Structuring coding prompts to ensure the LLM adheres to specific programming languages, libraries, and error-handling constraints. - Standardizing team prompt templates for customer support bots to ensure consistent, polite, and accurate replies. ## Frequently asked questions ### How does the tool score my prompt? It evaluates your input based on clarity, completeness, and ambiguity, providing a numerical score for each metric. ### What sections are included in the structured rewrite? The optimized prompt is organized into Role, Task, Constraints, and Few-shot sections. ### Can I optimize prompts in languages other than English? Yes, you can select your preferred output language, including English, Chinese, Spanish, French, German, Portuguese, and Russian. ### What does the 'Use AI Rewrite' option do? It leverages DeepSeek v4 to perform a more advanced, context-aware rewrite of your prompt. ### Do I need to write the Role and Constraints myself? No, the optimizer automatically infers the ideal role and constraints based on your raw input. ## Related tools - [AI Prompt A/B Variant Generator](https://elysiatools.com/en/tools/ai-prompt-ab-variant-generator): Generate controlled A/B variants of a prompt across the persona, tone/style, output format, and constraints dimensions, then compare them side by side with a heuristic rubric score and a word-level diff against the baseline. A reproducible way to test how a prompt behaves under different framings before picking one for production. - [AI LLM Photo Retouch](https://elysiatools.com/en/tools/ai-image-style-sharp-optimizer): Use a vision LLM to recognize the image and automatically retouch it - [Spring Compression Energy Calculator](https://elysiatools.com/en/tools/spring-compression-energy): Calculate the elastic potential energy and force of a spring in compression or extension. U = ½·k·x², F = k·x. Solve energy from displacement, or displacement from energy. - [Stress & Strain Calculator](https://elysiatools.com/en/tools/stress-strain-calculator): Calculate engineering stress σ = F/A and engineering strain ε = ΔL/L₀ under uniaxial load. Choose what to solve: for stress, enter force F (N) and cross-section area A (mm²) → result in MPa; for strain, enter original length L₀ and elongation ΔL (negative for compression) → dimensionless ratio. Units are self-consistent (N, mm) so stress comes out directly in MPa. - [Wells Score for Deep Vein Thrombosis (DVT)](https://elysiatools.com/en/tools/wells-dvt-score): Calculate the Wells score to estimate clinical probability of deep vein thrombosis (DVT). Components: active cancer (+1), paralysis/paresis/recent plaster immobilization (+1), recently bedridden ≥3 days or major surgery ≤12 weeks (+1), localized tenderness along deep veins (+1), entire leg swollen (+1), calf swelling ≥3 cm vs other leg (+1), pitting edema confined to symptomatic leg (+1), collateral superficial (nonvaricose) veins (+1), previously documented DVT (+1), alternative diagnosis at least as likely as DVT (−2). Reports BOTH interpretations: three-tier (low ≤0 ~5%, moderate 1–2 ~17%, high ≥3 ~17–53%) and dichotomized two-tier (DVT unlikely ≤1 — a negative D-dimer rules out; DVT likely ≥2 — ultrasound/D-dimer). Derived from Wells 1997 (Lancet) and the Goodacre 2005 (BMJ) meta-analysis.
