Frequently asked questions

Which LLM is the output tuned for?

The structured shape (role · context · task · constraints · format · examples) is model-agnostic - it works well on GPT-4o, Claude, Gemini, Llama, and Cursor. Individual presets nudge phrasing toward what each model handles best.

Is my prompt sent to any AI service?

No. This tool is deterministic string manipulation - it doesn't call any AI. Your prompt never leaves the browser.

Why does prompt structure matter?

LLMs perform better when they know their role, the context, the exact task, the constraints, and the expected output shape. A one-line prompt leaves most of that implicit - the model guesses.
