Based on visible product behavior
Prompt Improver rewrites the instruction, not the answer.
The page shows before/after examples, an already-good state, and a web quota bucket of 10 runs. Provider wording is scoped to the current prompt service; model availability and quotas can change in the live product.
Best for
Turning rough instructions, briefs, study tasks, and review requests into clearer prompts with role, task, constraints, and output format.
Not ideal for
Answering the question for you, sourcing facts, buying prompt templates, or fixing a task that is missing key information.
In short:
Use Prompt Optimizer when you know the job you want done, but the instruction is too vague for consistent AI output. It is not a chatbot and not a prompt marketplace.
