AI Prompt Optimizer: Rewrite Prompts for Better Results
Drop in a rough prompt and get a polished, structured version, with the task, constraints and output format spelled out for ChatGPT, Claude, and Gemini.
Stop fighting your prompts
Most prompts under-perform for the same handful of reasons: vague instructions, missing context, no role, no output format, no examples. Our prompt optimizer reads your draft, works out what you are asking for, and rewrites it with the structural patterns that work across modern LLMs.
The output is a rewritten prompt, with a role or context when it helps, an explicit task, and the constraints and output format your draft left out, ready to paste into ChatGPT, Claude, Gemini or any other model. It stays in the language you wrote in.
What the optimizer does
States the task explicitly, with a role or context when it helps
Adds the constraints, output format and tone your draft did not give
Adds step-by-step reasoning instructions when the task is complex
Removes filler, politeness and ambiguity
Adds edge cases or examples when they are useful
Rewrites the prompt without answering it, and returns only the prompt
Under the result, the panel shows how much shorter or longer the new prompt is than your draft, so you can see whether it grew or was trimmed.

Frequently asked questions
Which models is it tuned for?
None in particular, and there is no model picker. The rewrite follows patterns that work with ChatGPT, Claude, Gemini and other LLMs alike.
Does it change the meaning of my prompt?
It is instructed to keep your intent and your language, and to rewrite the prompt without answering it. It does not ask clarifying questions, so read the result before you use it.
Will the optimized prompt be longer?
It depends. Filler and politeness are removed, but a missing output format or constraint is added, so a one-line prompt usually grows. The panel tells you how much shorter or longer the result is.
Is it useful for short prompts?
Yes. Even one-line prompts gain from added role, output format, and constraints.
Can I save my prompts?
There is no prompt library. The History menu keeps your last ten results, across all tools, in this browser.
Does it work with system prompts?
Yes, paste one like any other prompt. To write one from a description instead, use our System Prompt Generator.
