Aether uses your own API keys to call LLM providers directly from your device. There is no proxying, no Aether account, and no subscription — you bring your keys, and Aether connects straight to the provider’s API on your behalf.

​
Adding a Provider

1

Open Providers settings

Open Aether, then navigate to Settings → Providers.
2

Tap Add Provider

Tap the Add Provider button at the top of the Providers screen.
3

Select your provider

Choose your provider from the list (for example, OpenAI or Anthropic).
4

Paste your API key

Paste your API key into the key field. Make sure there are no leading or trailing spaces.
5

Save and verify

Tap Save. Aether immediately validates connectivity to the provider using your key and confirms the setup was successful.

​
Editing or Removing a Provider

  • Edit: Tap any provider row to open its detail screen and update the API key or other credentials.
  • Remove: Swipe left on the provider row or open the row menu and select Remove.

​
Switching the Active Model

After you add a provider, tap the model selector in the chat composer (the pill-shaped button showing the current model name) to open a full list of models available across all your configured providers. Tap any model to switch to it for the current session or set it as your global default in Settings → Model.
API keys are stored in Aether’s private app storage on your device. They are transmitted only to the respective provider’s API endpoint — never to any Aether-operated server.
If you uninstall Aether, your stored API keys will be permanently deleted along with all other app data. Back up your keys in a password manager or secure location before uninstalling.
