API Key Management.

PromptDC supports a bring-your-own-key (BYOK) workflow for Lifetime users. You can add your own OpenAI API key to use your own OpenAI credits while keeping the same PromptDC coding-first rewrite flow.

What this controls

API key management controls whether PromptDC can use your personal OpenAI API key in supported flows. It does not change the core product position: PromptDC remains a coding-first prompt rewriter that prepares implementation-ready instructions before model execution.

  • Available only on the Lifetime plan.
  • OpenAI API key only (no Anthropic or Gemini BYOK in this flow).
  • Usage is billed to your own OpenAI account and uses your OpenAI API credits.
  • Keep rewrite settings (mode, format, language) consistent across sessions.

Where to add your key

Chrome extension (web AI apps)

Add your OpenAI API key from your PromptDC account subscription page at/account/subscription. The key is stored locally in your Chrome browser. PromptDC does not have access to your locally stored API key.

IDE extensions (Cursor, VS Code, Windsurf, etc.)

Add your OpenAI API key in your PromptDC profile settings inside the IDE extension. The key is stored locally in your IDE environment, not on PromptDC servers.

Setup steps

  1. Confirm your account is on the Lifetime plan (BYOK is not available on other plans).
  2. Add your OpenAI API key in the correct location: /account/subscription for Chrome, or PromptDC profile settings in your IDE extension.
  3. Save the key locally on your device and verify the setting is enabled.
  4. Run a test rewrite to confirm the flow and your rewrite settings (Simple/Structured, format, language, custom prompt override).
