Codex never calls an AI — you are the courier. Copy the prompt, run it in any chat AI, paste the JSON back. Everything stays on this device.
If the copy button can’t reach the clipboard (some browsers block it on local file:// pages), the text is auto-selected — just press ⌘C / Ctrl+C.
Paste the prompt into any chat AI. It returns one JSON object in Codex’s schema. Copy that JSON.
Saved domains live in this browser’s storage, keyed to this file’s exact path — moving or renaming the file loses them. Export is the real backup; Import restores anywhere.
