Sign in with ChatGPT

Use your existing ChatGPT account — no API key, no separate billing. ClipSlop authenticates via OAuth 2.0 with PKCE and calls the same chatgpt.com backend the official Codex CLI uses.

Setup​

  1. Open Settings → Providers (⌘,).
  2. Click OpenAI (Sign in with ChatGPT).
  3. Click Sign in. Your browser opens auth.openai.com.
  4. Authenticate (or confirm if you're already signed in).
  5. The browser redirects back to localhost:1455 and the connection completes automatically.

That's it. Tokens are stored in your macOS Keychain.

What you get​

  • Free usage subject to your existing ChatGPT plan limits (Free, Plus, Pro, Team).
  • Access to the same models and reasoning effort settings the ChatGPT app exposes.
  • No separate API billing.

When to use a different provider​

  • You need a model that isn't available through ChatGPT.
  • You want fine-grained control over temperature, top-p, or other API-level parameters.
  • You want to use ClipSlop heavily and stay within an organisational API quota.

In any of those cases, see OpenAI API instead.

Under the hood​

If you're curious about how the OAuth + PKCE handshake works, the Develop → ChatGPT OAuth page has the technical details.
