The Aiven Prompt Optimizer is a free online tool that rewrites your LLM prompts to improve clarity, structure, and token efficiency — without changing your intent.

Paste your prompt, select one or more optimization goals (reduce cost, improve clarity, add structure), and click Optimize prompt. You can also add custom instructions, such as a target model or output format.

Your prompt is only sent when you click optimize, so we can generate the result. We do not use it to train models.

The Aiven Prompt Optimizer is free.
