Use your ChatGPT subscription (Codex)

If you already pay for ChatGPT Plus or ChatGPT Pro, you can plug that subscription directly into Clawify and skip per-token billing entirely. Your assistant runs on top of the same models you already pay for, including GPT-5 / GPT-5.5.

Plan requirement

Codex sign-in is available on the Growth and Business plans (BYOK feature).

How to connectDirect link to How to connect​

  1. Open Clawify → Assistant settings → AI Model tab.
  2. Scroll to Bring Your Own Key.
  3. Click the ChatGPT subscription (Codex) row.
  4. Click Open ChatGPT sign-in. A new tab opens on auth.openai.com.
  5. Sign in with the same account you use for ChatGPT.
  6. After accepting, your browser is redirected to a http://localhost:1455/auth/callback?code=… URL. The page will fail to load — that is expected.
  7. Copy the full URL from the address bar (it must include code=…&state=…).
  8. Paste it back into the Clawify modal and click Complete sign-in.
  9. Your agent restarts. The assistant now uses your ChatGPT subscription. Default model becomes GPT-5.5.

Switching the default modelDirect link to Switching the default model​

Once connected, the curated model list in Default AI Model shows the ChatGPT-tier models tied to your subscription. Pick whichever one you want to use by default.

DisconnectingDirect link to Disconnecting​

In Assistant settings → AI Model → Bring Your Own Key, open the Codex row and click Remove subscription. The OAuth refresh token is revoked, and your assistant falls back to the Clawify-managed AI credits.

TroubleshootingDirect link to Troubleshooting​

  • "State mismatch" / "Invalid code" → the redirect URL was pasted incomplete. Copy the full URL from the address bar (everything starting with http://localhost:1455/).
  • Sign-in tab redirects to ChatGPT homepage instead of the callback → you are already signed in to ChatGPT. Sign out, then click Re-open sign-in tab in the modal.
  • Browser blocks the popup → allow popups for clawify.app and try again.
  • Connected but the assistant still says "no credits" → the agent didn't restart cleanly. Open Assistant settings → AI Model, change the default model, save. The instance restarts and picks up the OAuth tokens.
