Does my JSON file get uploaded?
Local editing processes selected and pasted contents in your browser. Optional Assistance sends your goal and only the context you explicitly prepare and include, such as a selected subtree or observed query field metadata, to OpenRouter and the configured model provider. Its preview shows exactly what is included. Ordinary page and asset requests also reach the hosting provider.
