Setting up API key users

How to get an API key

Important: Your API key is a secret that allows making requests to the API which you will be charged for. Keep it safe. If you think the key has been compromised, revoke it and create a new one.

Sumr supports multiple providers:

OpenAI setup steps

  1. Go to OpenAI Platform and sign up (or login)
  2. Select API from the menu and click Get Started
  3. Open API keys
  4. Enter a name for your API key and click Create secret key
  5. Copy your API key and store it someplace safe (ideally in your password manager)
  6. Add a billing method: Settings → Organization → Billing → Add to credit balance
  7. (Optional but recommended) Set usage limits

Sumr is not storing your API key in iCloud or on any other server. If you need to reinstall the app, the key will not be preserved.

Tip: if you lose your key, revoke it and create a new one so no one else can use it.

Paste your key in Sumr

Go to Sumr app → Settings → select your provider → paste your API key. The key will autosave.

Tip: on macOS you can use Cmd+A to open the API key section and Cmd+V to paste. Cmd+E will clear the key.

Safari extension setup (legacy method)

Note: The Safari extension is now a legacy feature. We recommend using the Share menu method above for the best experience.
