How the optimizer works
This is a rule-based restructuring tool, not an AI rewriter. It splits your prompt into sentences and sorts each one with keyword rules, then rebuilds the prompt in the order of the framework you pick. Your wording stays the same, so you keep full control over what the AI is asked.
What it looks for
- Role: phrases like "you are", "act as" or "pretend to be".
- Task: sentences that start with a verb (write, list, plan) or a request such as "I need a…".
- Format: lists, tables, JSON, Markdown and counts such as "5 ideas" or "200 words".
- Tone, audience and goal: tone words (friendly, formal), who it is for and phrases like "so that" or "the goal is".
- Constraints and examples: "don't", "avoid", "must", word limits, and text in quotes or after "for example".
Getting the most from it
Write one instruction per sentence. A sentence that mixes a role, a task and a tone can only go in one section. After restructuring, replace each [Add …] placeholder with real detail. Filling in the audience and an example usually improves answers the most.
How it works
How to use it
- Step 1
Paste your rough prompt
Paste the prompt you would normally type into ChatGPT, Claude or Gemini, even if it is one long messy paragraph.
- Step 2
Choose a framework
Pick RACE, CO-STAR, CREATE, APE, SPARK or RTF and restructure. Each sentence is sorted into the matching section.
- Step 3
Fill the gaps and copy
Check the score, replace any [Add …] placeholders with your details, then copy or download the improved prompt.
FAQs
Frequently asked questions
Answers to common questions about the AI Prompt Optimizer.
No. It is rule-based. It splits your prompt into sentences and sorts each one by keyword patterns: role statements such as 'act as', instructions that start with a verb, format requests, tone words, rules like 'don't' or 'must', and quoted examples. It then places them into the framework you choose. Your text is never sent anywhere.
No. It keeps your sentences as you wrote them (only capitalising the first letter and adding a full stop where one is missing) and reorders them under clear section labels. Sections it could not fill get an [Add …] placeholder so you can see exactly what is missing.
The score checks seven things good prompts usually include: a role, a clear task, context, an audience, an output format, constraints and an example. Each one found adds a point. A low score does not mean the prompt is bad, only that the AI will have to guess more.
Keyword rules can misread a sentence, for example a sentence that contains both a task and a tone. The output box is editable, so move or rewrite anything before you copy it. Each sentence's detected type is listed under the score so you can check.
RACE is a good default. CO-STAR suits writing where tone and audience matter, CREATE suits prompts with examples, SPARK suits problem solving, and APE or RTF suit short, simple requests.
The tool reads the first 20,000 characters of your prompt. That is far longer than most prompts.
