API Key Management.

PromptDC Lifetime requires a bring-your-own-key (BYOK) setup. Add your own API key from OpenAI, Anthropic (Claude), Google (Gemini) or xAI (Grok), choose which provider and model to use, and run on your own API credits while keeping the same PromptDC rewrite flow.

What this controls

API key management controls which provider key PromptDC uses in supported flows. It does not change how the product works: PromptDC still runs the same prompt & writing enhancement flow — only the provider and model behind it change.

  • Required on the Lifetime plan and unavailable on monthly plans.
  • Add keys for OpenAI, Anthropic (Claude), Google (Gemini) and xAI (Grok); pick which one is active and choose its model.
  • Usage is billed to whichever provider account owns the active key, using your own API credits.
  • Keep rewrite settings (mode, format, language) consistent across sessions.

Where to add your key

Chrome extension (web AI apps)

Add your provider keys from your PromptDC account subscription page at/account/subscription, then pick the active provider and model. Keys are kept in your browser's local storage and pushed to the PromptDC extension — not persisted on our servers — and are sent through PromptDC's backend to your chosen provider only to run each request.

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

In the IDE extensions, add your provider keys in the PromptDC settings panel inside the editor. Keys are stored locally in that editor only — they are not synced between devices or editors, and never persisted on our servers.

Setup steps

  1. Confirm your account is on the Lifetime plan (BYOK is not available on other plans).
  2. Add one or more provider keys (OpenAI, Claude, Gemini, Grok) at /account/subscription, then choose the active provider and model.
  3. Save — your keys are pushed to the Chrome extension in this browser. For VS Code / Cursor, add the key once in the editor's PromptDC settings panel.
  4. Run a test rewrite to confirm the flow and your rewrite settings (Simple/Structured, format, language, custom prompt override).
