This is where your own OpenRouter key lives, encrypted, so that every studio tool can use it without any of them keeping a copy. Sign in with the Google account you were enrolled with.
Paste your own OpenRouter key here once. It is encrypted before it is stored, it is never shown again, and no tool keeps a copy of it after the session it is used in.
Your own credit, totalled. There is no record here of what you made, when you worked, or which tool you used — only the running figure.
