Behavior knob-board, deterministic compile
Turn the knobs, get a better prompt.
Type a lazy prompt. Dial the behavior you want. Copy the compiled prompt into Claude, ChatGPT, Gemini, or anything else. No LLM call here. Just structured engineering of what you actually meant.
1. Your lazy prompt
Half-worded is fine. The dials do the rest.
2. Persona (optional)
Who should the model act as? Free text + presets.
3. Dials
Each 1–5. The compiled prompt updates live.
4. Compiled prompt
Plain text. Paste anywhere.
About this tool
Built from Victor del Rosal's idea: LLMs are a mirror for how we talk to ourselves. If you can see the knobs, you can shape the answer. The dials are deterministic: each level maps to a fixed snippet, concatenated in a stable order. No model call, no surprises, no per-token cost. The output is the prompt; what you do with it is yours.
Share a configuration by copying the URL. The dial state is encoded in the query string.
Keyboard: T toggles theme, R resets, C copies.
