Where to use your prompt

A) Chat tools (ChatGPT / Playground)

Clean Prompt: Paste into the chat message. If you set System, paste it into the tool’s system/instructions field (or send first).
Playground/API (JSON): Use the OpenAI JSON tab. It contains messages, model and optional response_format when a schema is used.

curl -s https://api.openai.com/v1/chat/completions \
 -H "Authorization: Bearer $OPENAI_API_KEY" \
 -H "Content-Type: application/json" \
 --data-raw '<>'

B) Image apps

Midjourney (Discord): /imagine + paste Clean Prompt. For aspect ratio add --ar 16:9 (etc). To exclude terms, append --no + items from Avoid.
DALL·E: Paste the Clean Prompt into the prompt box. (No explicit negative prompts; refine wording.)
Stable Diffusion (AUTOMATIC1111/ComfyUI): Paste Clean Prompt into Prompt. Paste Avoid (and Avoid (auto)) into Negative Prompt. Match the aspect ratio.

C) Video apps

Runway / Pika: Paste the Clean Prompt. Set duration (e.g., 5s), FPS (e.g., 24), and AR in the app. If there’s a Negative Prompt field, paste Avoid.

Tips

Lens & Lighting chips auto‑dedupe into Include keywords.
Midjourney: concise subject‑first phrasing; add --ar and optional --stylize.
Stable Diffusion: split style tags between Prompt and Negative Prompt.
JSON extraction: provide a realistic schema; set Max tokens high enough.

Troubleshooting

Copy blocked? Click anywhere on the page, then try again.
Invalid JSON? Ensure the schema is valid JSON (no trailing commas, quotes balanced).
AR/Duration/FPS missing? Select a chip or type a custom value, then click Generate again.
